Trang 3SketchUp is open 3D software with a graphic concept It was designed for architects, designers, carpenters, engineers, civilians, movie makers, computer games programmers and related professions It’s easy to learn because of its use of a mouse and because it is intuitive The free form of building a model with this program simulates as much as possible sketching
on paper and does not require exact numerical data or scaling of one kind or another The output of models made with SketchUp can be presented in various ways, including computer printouts, images that have been refined with rendering software, a short film that illustrates the space exactly and realistically, and even 3D printing SketchUp software is designed also for people with no experience in three dimensions.
In order to control and maneuver within the software, you just need to have a three-button mouse.
Windows and Macintosh
SketchUp software works similarly in both Windows and Mac operating systems, with the exception of a few interface variances.
One of the differences that is good to know can be seen in the keys of the keyboard The
“Ctrl” key in Windows is parallel to the in Mac The “Alt” key in Windows is parallel to the
“Option” key on the American Mac keyboard Thus, for example, saving a file is done with the shortcut Ctrl+S in Windows and by ( +S) in Mac Most of the commands in SketchUp have keyboard shortcuts of one letter and for the most part they are identical in both operating systems.
Choosing the Appropriate Version
Sketchup Pro, the paid version, is designed for commercial use and in a commercial environment Professionals who use SketchUp as a work tool benefit from all the options and extensions that are included in the software, including importing and exporting of all types of files Each version has its own unique and specifically tailored hardware and software specifications and you should verify that your computer is capable of performing all these tasks.
All you need to do is to enter SketchUp site, download the software in the version suitable for you and try it out for a 30-day trial period before deciding whether to purchase the software SketchUp Software is installed automatically on a computer in a designated path in both operating systems The various versions of SketchUp might installed in different paths Of course, if you prefer, you can independently install the software in a different path.
This Book
This book is updated for the latest version and relates to all the principles of SketchUp that have existed since the first version The manual is divided into five chapters The study chapters contain all the material that is required to become familiar with the SketchUp software and the most correct and efficient forms of work The manual presents all the program’s commands and guides you through dozens of examples, exercises and screen-
Trang 4shots In addition, the manual will teach a wide variety of subjects from the Pro version Learning the software with the manual will turn you into experts in SketchUp and Layout.
At the end of the learning process, which is recommended to do in conjunction with a practical course, the reader will have all the required tools for building models, presenting them and for using them in this and other accompanying software.
Enjoy the manual and the ease of creating your projects.

Fundamentals 1 –
Becoming Familiar with SketchUp
Trang 12SketchUp Pro Quick Reference Card | Windows
Trang 13New Way to SketchUp |
As of 2019, Sketchup allows several ways to use the
software: Via Internet browsers, via the cellular devices or via the classicway of downloading SketchUp to a computer
Each choice will also be adapted to a particular type of licensing, whichallows the user to choose the most suitable way for him
For those who are interested in the classical way, it will be necessary toinstall the software
Trang 14Installing the desktop program
SketchUp has created a simple and easy method of installation, that allowsevery user to install the program by themself with a minimum of clicks andapprovals The installation is quite similar between the various versions andrequires the user to approve the operation, the designated path and to startthe installation
In the advanced versions, SketchUp requires installation of a MicrosoftVisual Plug-in, which allows for running the software in an optimal manner
Stage 1: Left-click on the installation file The installation file will be different
from version to version and between the Windows operating systems(where it will be displayed with the exe suffix) and the Macintosh operatingsystems (where it will be displayed with the dmg suffix) Right click onSketchup shortcut and choose "Run as ight click on Sketchup shortcut and choose
"Run as Administrator"" Running the file will open the SketchUp installer
Stage 2: Clicking on approvals and requesting installation During this stage,
you will need to click twice on the button “Next” and an additional time onthe button “Install” in order to install the software SketchUp will display its
permanent installation path on drive "C" Should you prefer a different path,
it’s possible to change it by clicking on the button “Change”
Stage 3 – Completing the installation.
Upon completion of the installation, SketchUp will display the button
“Finish”
Trang 15Initial acquaintance with the software
Installation of Sketchup will place three icons on the
desktop for quick entry: Entry into SketchUp, entry
into Layout and entry into Style Builder.
A double click on the SketchUp icon will display an introductory window
“Welcome to SketchUp” From here it’s possible to manage your license, tolearn more about SketchUp through training videos and written material, toselect a template, or to just start using Sketchup In the newest version,users will be required to sign in with an account, in order to download andopen SketchUp
Method of Operation:
1 Access to Sketchup can vary between different versions licensing isdivided between typing your email for an annual license or two key codesfor a classic license
Since version 2019 version, SketchUp users are required to sign-in withTrimble connect account or Gmail account to SketchUp This is in addition toentering the license code's or email
The registry allows the user to be identified and thus be able to use allSketchup apps, such as the 3dwarehouse Extension warehouse and more(Illustration 1)
2 Choosing a template from the various templates that exist is the nextnecessary step, and it's applied to all versions of SketchUp The templatesare different from one another in units of measure, in display and inbackground colors These templates assist the new user in understandingSketchUp’s 3D environment Our recommendation is to select the templatethat is closest to a 2D view program
In version 2019, it is been done by clicking on "Files" button and selecting a
template Various of templates to choose from will be displayed (Illustration
2) Click on the "More templates" which will display all the options that exists, and select the template “Plan View - Meters”.
Trang 16In the older versions of SketchUp – you would need to click on the button
“Choose Template” and select the template "Construction Documentation
– Meters" In this way it will be easier to learn about the basic functions of
SketchUp
For those who are working in other measurement units, it’s possible toselect the same template in units of millimeters or in feet and inches.Adapting the template to centimeters is easy to do, and will be shown later!
In the older versions of SketchUp – you would need to click on the button
“Start using Sketchup” and SketchUp will launch.
First thing first - Opening a Work File in Sketchup
When opening the program, SketchUp will open a main work file without adefined name (untitled), that will be displayed with the skp suffix Startworking by saving your file in a desired location and protect your work Ifyou are about to save the file locally and not through the cloud, save yourwork in one of the computer's drives and not on the desktop Saving files onthe computer's desktop, takes resources from your computer's short-termmemory (RAM) Only when a file has a path, it can create a backup file and itcan be saved securely
Please notice! After closing the file, a backup file will also be displayed, withthe skb suffix
Trang 17Defining a template and compatibility with the work environment
It is recommended to create a personal template that is adapted to yourwork needs The idea is to save all the settings that fits you as a user and tomake it permanent and direct (for example: background color, compatibility
of size of the display, units of measurement and icon taskbar) This way,they will appear in every new file that is opened and allow you to startworking without a delay The recommendations here relate to a method ofworking in units of centimeters
Adjusting Background Color of the Screen
When beginning work, the recommendation is to differentiate thebackground color (white) from the color of the faces, in order to achieve abetter space orientation
1 Navigate with the mouse to the right side of the screen, where theprogram trays are displayed
2 Open up the "Styles" tray by clicking on the tray name
*(In older versions and on Mac computers, the Styles tray appears under theWindow toolbar)
3 Click on the Edit tab
4 Click on the third square from the left (marked with a red square),which contains the background settings Note that on the right side the
word Background is displayed.
5 Left-click on the mouse on the color square (marked with a blue square),and change the color of the background You will be able to change thehue and to set its lightness/darkness *It is recommended to work withlight colors After choosing the desired color, click on OK, and the changewill be seen immediately on the screen For those interested in displaying
Trang 18a horizontal edge of ground and sky, you can check on the left side of thewords Ground and Sky, and there too you can define the colors.
6 Click on the update style icon (marked with the green square) andclose the tray by an additional click on the name of the “Styles” tray Notethat you do not click on the X , which will completely cancel the traydisplay
Adjusting the icon toolbar
The reason for adjusting the icon toolbars is to allow direct access for usingcertain commands When entering SketchUp, only one icon toolbar isdisplayed, which enables initial work in SketchUp
For PC Users:
Adjusting the toolbar is done by entering the top menu: View > Toolbars
and marking all the relevant categories for your work In the window that isdisplayed you can check any category that you want to add and it willimmediately be displayed on the screen Some are repetitive Here are thecategories names for markup (You can also refer to Illustration 1): Large Tool
Trang 19Set, Measurements, Tags / Layer (depending on version), Sandbox, Sections,Shadows, Standard, Styles, Views and Warehouse.
Once these icons appear on the drawing screen, you can move and placethem by dragging the handle In the horizontal layout the handle appears asgray dots on the left edge of the icons In the vertical layout, the handle is onthe top notch
After these icons appear on the screen, you can move them and place themwherever you want by dragging the handle on the edge of the icons
Position the cursor over these points and drag it wherever you want Thelayout of the icons affects the size of the drawing screen Therecommendation is to create a top horizontal row, a horizontal row at thebottom and a double column to the left side of the screen
In time, icons rows will be added and the number of icons will increase Theicons layout affects the size of the sketching screen For owners of a smallscreen, or users who have multiple icons, it’s possible to reduce the icons’size Click on the Options tab and remove the check mark from Large Icons(Illustration 2) To finish, click Close and the screen will fill up with icons
[Tip]: At any time, you can add more toolbars by right-clicking on any of theicons and the list of icons will again appear By clicking on a specificcategory, you can add the desired icons
Trang 20Mac Users:
Navigate the top menu: View > Tool Palettes, select the top option "LargeTool Set" and a large, main toolbar will be added on the left side of thescreen This is an independent toolbar and you can place it on the screenwherever is most suitable for you (Illustration 3)
Go again to the top menu View and select the bottom option “CustomizeToolbar” The window that opens will display the command icons in thesoftware Dragging them to the top toolbar of the screen will add them tothe screen The recommended icons for work are marked below in redsquares When you have finished, click Done (Illustration 4)
Trang 21[Tip:] In both operating systems, where the Toolbar window is open(Illustration 1 in PC and 4 in Mac), it’s possible to edit the icon bars You candelete icons from a bar by dragging them into the modeling space You canalso edit and create your own custom toolbar by dragging them to anotherbar.
For example, on Pc computers, we recommend to drag the "Extension
Manager" icon and the "User Info" icon to the Standard icons on
the right side, as it displays here
These icons are stored under the "Getting Started" bar, which will not
continue to be displayed First, display this bar and drag the icons to theright place for you Then you can uncheck this bar
Adjusting the toolbars is something you can change frequently When youclose SketchUp, the last icon display is saved
Trang 22Adjusting the Units of Measurement
1 In order to adjust the units of measurement, navigate to the upper
toolbar Window > Model Info or click on the icon
The recommended template is offered in several versions and you can selectthe units of measurement that are best for you For those working inDecimal and centimeters, this is the place to make this adjustment Theadjustment is made independently by clicking the arrow that opens below.The significance of adjusting the unit of measurement is that it is possible toconvert each model to other measurement units Sketchup’s advantage isexpressed in that the chosen units are adapted to the existing modelwithout changing anything So, if you want to move to units of millimeters,inches or meters for a particular calculation, you can do it easily Then, withthe same ease, revert back to your regular units For users that usescentimeters units, match illustration number 2
2 In any case, the recommendation is to set “Enable Length Snapping” not
more than 0.1 in order to allow sufficient zooming of the cursor whileworking on the model
3 Closing the window is done by clicking on
4 After these changes are made, go the top toolbar and choose File > Save
as Template In the top box under 'Name' type the template's name This
Trang 23can be your first name or for example “Plan view – cm” Left-click with themouse on the bottom box “File Name” and you will see that the name of thetemplate has been copied there Verify that the bottom box (Set as a defaulttemplate) has been checked, and from now-on this can be your defaulttemplate After saving it, the new template will be available on SketchUp’sopening screen and will also be added to the template menu.
In older versions, you can change the template, via Help menu, and thenchoosing “Welcome to SketchUp”, which will again display the openingscreen, where you can again select a different template The change will bedisplayed when opening a new work file, which will update the chosentemplate
An additional way is via 'Window' menu and select 'Preferences' [Mac users:from the 'SketchUp' menu, select 'Preferences'] Click on 'Template' at thebottom of the list on the left side, and select the appropriate template Tofinish, click on “OK”
Trang 24The Drawing Screen
Icons row – icons are displayed on the SketchUp screen at the top andbottom and on the left side Left-clicking on any of them will allow you toenter the desired command
Modeling area– this is the area where models will be built and actionswill be done This area appears with a background color and with axes
Values entry box – located on the bottom right or bottom left of thescreen This is the box responsible for entering numerical values Thedescription of the entry value will change in accordance with the command
Upper toolbar – located at the uppermost part of the screen, andcontains all the SketchUp commands that are in all the various toolbars.Also, these toolbars contain all the program settings and preferences thatcan be adjusted The windows are dynamic and it is possible to decide ondata and to see them immediately applied on the model
Menu trays – for Windows users, a Default Tray Menu has been added
to the right side of the screen that allows you to display collapsible trays in
an organized and personally customized fashion (for example, styles, scenes,
Trang 25elements, etc.) These trays allow work in parallel with a number of menus,something that was not available previously This has created a matchinginterface with the Layout program This tray is managed by entering themenu Window > Default Tray There you will be able to display or hide the
trays and to set the menus of trays Opening and closing the trays is done
by clicking on the name of the tray and not by the X Clicking on the X will
delete the tray from the list of trays If this happens, it can be retrievedthrough the main menu Window > Default Tray
Computers with the Mac operating systems – theorganization of menus will be done from within the Window menu at theupper toolbar It is also recommended here to close the trays by clicking onthe name of the tray and to organize them nearby in an organized manner
Trang 26Adjusting menus and preferences
Entry into the menu Window > Preferences (Mac users: Sketchup >Preferences) will display a window with various settings for working with thecomputer These settings are explained throughout the manual It isworthwhile at the beginning of work to adjust two of these settings Thefirst, saving files under the setting Files
These paths group within them according to various categories, thedestinations for saving all the files that are associated with SketchUp A click
on the folder icon will allow entry into the associated folder A click on thepencil icon will allow to change its' location
Adjust the destination for saving files in the top row under the setting
“Models” Thus, every file that is opened and saved automatically will get toyour chosen folder Adjusting the paths will allow direct access to the stock
of elements and materials on the computer and to add your own folders.This window is very significant because there is a separation in the SketchUparchive and this allows easy and direct access to the various folders (will beexplained in greater detail later)
The second setting is found under the name Drawing and is connected tothe method of work in SketchUp Entering this window allows you to selectthe correct method of clicking for work with the mouse For this purpose,
we will present the function of the mouse clicks and explain the method ofsketching in Sketchup
Trang 27The functions of mouse clicks
There are three different terms for use with the mouse – Click (often called left-click), Dragging and Right-Click (sometimes called the right context
Right-Click - (or Right Context) means clicking on the right mouse
button and then lifting the finger without moving the mouse (figure number3)
The method of clicking in SketchUp is called Click – Release – Click, the
meaning of which is a click on the left mouse button, lifting the finger,moving the mouse and to conclude, clicking again on the mouse button Thismethod is easier on the wrist and ensures better learning for new SketchUpusers In addition, you can pay attention to the screen without having toconcentrate on holding down the mouse button The clicking methodprevents accidently creating small segments throughout the model that cancause chaos in the model Avoid dragging the mouse button while drawing aline (Edges)
The method of clicking (Click – Release – Click) allows drawing continuous
lines as “a loop”, the significance of which is that during drawing, you create
a closed loop of edges Until the form is closed, the pencil command “willwant” automatically to continue drawing an additional edge from the end of
Trang 28the last segment.
On the other hand, the method of dragging the mouse button enables each
time the drawing of one edge only, and thus limits the efficiency of thesketch
[Tip:] Are you used to dragging the mouse and have trouble with the new way of working?
SketchUp can help you The idea behind the operation of the mouse whenchoosing to drag the mouse button, is to move data or select a specific area.SketchUp emphasizes using this method when it is correct for the tool itself.However, ongoing work should be done by a single click, lifting the finger,moving the mouse to the desired position and clicking again to finish
With entry into Window > Preferences and choosing the setting “Drawing”,three ways of working in SketchUp appear:
Marking the top option, “Click-drag-release”, is good for those who
always drag the mouse and are interested in continuing in this mannerwithout destroying what has been done and without creating mistakes
in the file Note that this method will not allow continuous looping ofedges
The middle option, "Auto Detect", which is marked as the default,
allows automatic detection and will allow dragging the button and alsoreleasing it This is appropriate for someone who knows how to
differentiate between work methods and does not hold down the left
Trang 30Becoming familiar with the software – basic understanding
Even before learning the SketchUp commands, there are a few importantthings to understand:
Part of the understanding of software lies in understanding its creationand affiliating the various options within it to the relevant commands.SketchUp itself is divided into three different parts: edges (Lines),
faces (surfaces) and display (View) and that is how I have chosen topresent SketchUp to you These three divisions are equally importantand work side by side All the commands in SketchUp belong to one ofthese three divisions, and once you have learned to characterize
commands according to their use, it will be easier for you to
understand how to use them
Sketchup has two methods of work that apply to all commands in theprogram It is recommended to work with both and combine them:
The first method - taking data from the model This method works on
the grid principle, which means working in the direction of one axisand extracting data from another axis Working with this method isdone by placing the cursor on the place to which you want to refer Inthis way, SketchUp will extract the data by itself and collect the
relevant information and measurements In this method, the work isintuitive, quick and relates to spaces and areas
The second method - inputting exact values Work in this method will
be done by inputting numbers and then immediately pressing "Enter".The advantage of this method is the planning option When pressingthe Enter key, SketchUp will display what has been done according tothe value inputted In addition, you can input a new value and
examine its effects This can be done as long as we are in the sameprocess, i.e as long as we have not started a new process or moved to
a new command
Trang 31All the commands start in the same way - left-click and moving themouse The conclusion of the process is different.
One of the reasons that SketchUp is considered an easy and popularprogram is that the work principles are applied across the programand once you have understood a guiding principle, it can be applied to
a large number of commands
Many of the SketchUp commands allow for continuous work In caseswhere this is not desired, press on the ESC key, which will release theaction (and stop the operation), but will still leave you at the samecommand for further work
Trang 32Drawing lines – creating basic 2D geometry
In order to create a line, select the Line command by pressing or theletter "L" on the keyboard The line entity belongs to the edge division.While learning the Line command, we will become familiar with the twodifferent methods available in SketchUp
1 Start by clicking (left-click on the mouse) on the screen, release your
finger, and move the mouse around (let the cursor hover on the
screen) The screen will show a "rubber edge" that extends from thestarting point and changes with the direction of the mouse towardsthe cursor When the rubber edge is parallel (or aligned) with one ofthe axes, its color will change according to the color of the axis to
which it is aligned (red , green, or blue) The edge will display black
when it is not parallel to one of the axes
2 Left-clicking on the mouse will complete the edge segment and it will
be drawn in black color on the screen in the area of the model
3 Now move the cursor down to draw a vertical edge
Want to be Exact?
This is the way to work, while applying the second method;
1 Start by clicking in order to draw an edge Lift your finger from themouse button and move the mouse parallel to one of the axes
2 As soon as the edge turns into the color of one of the axes, input thenumeric value 100 To finish, press Enter
Trang 333 The edge will be adjusted to that length Note that once moving themouse, the line can be much longer or shorter, and SketchUp will
adjust it The Enter at the end of the process will set the final length.SketchUp does not require you to be precise, but if you want to, you can setexact measurements throughout the work Thus, it is possible at every step
to decide whether to be precise or not SketchUp displays the numeric value
in the lower right-hand or left-hand corner of the drawing window, in atoolbar called Measurements There is no need and no possibility to clickthis window to enter information because SketchUp accepts numeric inputduring the drawing process This toolbar is always showing data, even if youare not typing measurements and not using this method
The principle of planning is expressed starting from a small line Aftercreating the line, when you see the result, you have the ability to inputanother value and change the length of the line Input 20 now and thenEnter, and you will be able to see the line change according to what youinputted This method always ends with Enter Each value will update theedge to the last inputted number, which reflected the SketchUp designprinciple
Continue drawing edges Note that when the cursor is opposite the startingpoint on the screen, you will see a dashed edge that connects the cursor tothe starting point and that is displayed in the "From Point" tab This is called
Inference In SketchUp, each geometry refers to another and knows the
location of the other geometries SketchUp will display as many of thesepoints as possible, which are saved during work If you want to relate tothem, click on the mouse and compete the step
Trang 34The Delete function
The Erase command is the first command we will investigate that shows thedifference between edges and faces
Erasing Faces – Illustration 1
Erasing faces is done by placing the cursor above the face, right-clicking and
choosing the option Erase This action is possible for every command Note:
the loop of edges remains when the face is erased
Erasing Edges – Illustration 2
This Is done by entering the eraser tool Click on E on the keyboard or click
on Erasing edges is done only by clicking on the edge Note that erasing
is done only when the lower-left part of the eraser touches the edge Thispart looks like a circle The correct way to work is to drag (press continuously
on the click) and to pass above the edge, like when erasing on a chalkboard.The program’s graphics helps – each highlighted edge will be colored in blue.When releasing the mouse button, all the edges will be erased Clicking on atop edge that encloses a face, will erase both the edge and the face, becausefaces are defined by the borders of closed edges Erasing all edges and facestogether is possible by pressing the keyboard shortcut Ctrl + A (Mac users:Cmd + A), which will display all the edges in blue and all the faces with dots,followed by pressing the Delete key on the keyboard
Creating faces from within circles and polygons,
arches, free-hand and rectangles
It’s possible to create faces from other shapes In order to create a circle,press "C" on the keyboard or press on the icon Click any place on thescreen in order to locate the center point of the circle, input the numeric
Trang 35value in order to define the radius of the circle and to finish, press Enter Forexample, when you input 10 and immediately afterwards Enter, a circle with
a radius of 10 cm will be created (Illustrations 1+2)
Note: as was noted previously, the numbers and letters that are typedappear automatically in the measurement area (Values Entry Window) You
do not need to click on the box
Creating Faces from Polygons
Creation of polygons is done in a similar way In order to create a polygon,click on the command symbol Click on any place on the screen in order
to locate the center point of the polygon, input the numerical value of theradius of the polygon and click Enter (Illustrations 3+4)
Editing a Circle and a Polygon:
Right-click on the perimeter (the outlined edge) of the circle or the polygonand enter the Entity Info Tray that provides data about the edge This traycan be found in the upper right part of the screen (Mac users: Navigate toWindow > Entity Info) The data relates, among other things, to the value ofthe radius and to the number of segments Information as to the size of theface will be provided by right-clicking on the face itself and choosing EntityInfo The box grants immediate access to changes of key features of all theobjects in SketchUp, where it is possible to display or edit entities and to seehow it is carried out in the model The box that opens relates to the samemarked entity and includes detailed information
A circle that looks perfect varies according to the distance of the display Thenumber of segments should be changed only when necessary This window
is very useful, so it is recommended to leave this box open during theprocess of building the model
[Good to know!]: The default for a circle is 24 segments and for a polygon, 6segments It’s possible to change and to set the number of segments evenbefore laying out the face by typing in the number of sides and after this the
Trang 36letter “S” (for segments) To finish, press Enter In this way you’ll be able to
create a polygon with the number of segments that is correct for you.SketchUp will remember the last value that was inputted, so that in the nextuse of the tool, the shape will be created according to this value It isrecommended to do this only when using the polygon tool
Experiment by changing the polygon to 12 segments by inputting 12S Also,try to turn the same face into six segments by inputting 6S or into a triangle
by inputting 3S
The difference between a circle and a polygon
From the Entity Info tray, you can edit a circle and polygon If you want, you
can adjust the number of segments and the radius of a circle and a polygon
to the same value so that in effect, it appears that with one command it ispossible to get to the same results The difference is seen when the shape ispulled into 3D, where the circle will be pulled into a perfect cylinder,whereas the polygon shows edges that separate between divisions In caseyou want to build an independent column or a perfect cylinder - use thecircle tool If you want to build a pillar from which a wall extends - use thepolygon tool
Locating the Center of a Circle and a Polygon:
In order to find the center point of a shape, hover with the mouse over one
Trang 37of the green “endpoints” on the perimeter of the shape (the circumference)and move your mouse toward the center The cursor will “pop up” and a tab
with the caption "Center" will appear You can then relate to the center of
the shape and from it, you can create additional shapes Once that you haveestablished the center, SketchUp will put it into its memory and you willalways be able to relate to it
Drawing Arcs
Arcs are made up of multiple segments
connected as an edge (which can be edited
as a single arc) Starting with the 2015
version, the possibility has been expanded to
4 tools:
It is possible to run each of the tools using
the icons or via the Draw menu There are
three tools for drawing arcs and a tool for
drawing a pie
Two-Point Arc - Creating an arc according to the setting of its length withtwo points of reference
Trang 38Clicking on A on the keyboard or on will turn on the command.
Methodology:
1 Click to define the beginning the arc
2 Move the cursor on one of the axes
3 Click at the endpoint or input a value + Enter for setting the length ofthe arc
4 Finally, move the cursor perpendicular to the edge in order to set thedirection and protrusion of the arc Click on the desired place or input
an exact value + Enter
Arc Tool – Creating an arc according to the middle of the arc Click on theicon in order to enter the command
Methodology:
1 Click and define the middle of the arc
2 Move the cursor in order to define the distance from the middle of thearc You can also enter a value of the radius + Enter
3 Click and define the point where the arc begins
4 Move the cursor around the protractor and click or input the desiredangle + Enter
Three-Point Arc Tool – Creating an arc according to three reference points.Click on the icon in order to enter the command
Methodology:
1 Click and define the point where the arc begins
2 Move the cursor away from the beginning point in order to define thesecond point The arc will always go through this point
3 Move the cursor and click on the endpoint An angle will appear in theValues Box and it is always possible to type in an exact value + Enter
Trang 39Pie Tool – Creating pie entities Click on the icon in order to enter thecommand.
Methodology:
1 Click and define the center of the pie
2 Move the cursor and define the first arc point by clicking or inputting aradius value + Enter
3 Move the cursor around the protractor and click or input the desiredangle + Enter
Creating Rectangles While Determining Two Points
There are two ways to create rectangles: either clicking on the desire point
or inserting values
Methodology:
1 Click on the letter "R" on the keyboard, or click on the icon
2 Click on the screen at the starting point, release your finger from themouse and move the cursor to the desired place while opening therectangle
3 You can click to finish You can also input exact values, exactly like inall the other commands Input values for the opposite sides by use of a
comma between them and click on Enter on the keyboard.
The values will be inputted in the value entry edge and called Dimensions
-dimensions of the rectangle When looking from the Top, the first value will
be the width of the shape 350 (red axis) and the second a length of 200(Green axis)
[Tip:] Single Clicking on the Ctrl key will turn-on and turn-off the possibility
of starting the creation of the rectangle from its center In that case, click to
Trang 40set the center, move the mouse and click on one of the corners of therectangle or type the value of the shape Even though it is presented withreference to the center, the value is for the entire shape.
Creating Rectangles while Setting the Angle of
Rotation
An additional way of creating rectangles is to create the rectangle whilesetting the angle of rotation Click on the icon in order to enter thecommand
Methodology:
1 Click and define the first corner of the rectangle
2 Move the cursor around the protractor in order to set the direction ofthe first side Click or input a value + Enter and define the second
corner The value will be the length of the side
3 Move the cursor around the protractor in order to set the direction ofthe second side Click or input a value + Enter and define the third andlast corner The value will be made up of the value of the angle,
comma, and from the value of the side
Free-hand Drawing
Freehand drawing is done by clicking on Freehand is created by clickingand dragging while drawing the desired edge When the hand releases themouse, the edge will close The edge is defined as a Curve that is made up ofsegments and is one entity By right-clicking, it’s possible to select “ExplodeCurve” and it will become individual edges equal to the number of segmentsfrom which the curve is made Within an existing face, it’s correct to draw acurve from edge to edge
