Trang 3Autodesk Revit Building Overview
This Quick Start provides a simple tutorial designed to give you a quick tour of some of the most common elements and features of Autodesk Revit Building You should be able to complete the entire exercise in 30 minutes
or fewer At the completion of this tutorial, you will have experienced a first-hand look at what Revit Building has to offer
Install the CD Files and Open a Project
To follow along in the tutorial, download the dataset from the Autodesk University web site (A completed version is also provided)
1 Launch Autodesk Revit Building from the icon on your desktop or from the Autodesk group in All
Programs on the Windows Start menu
o From the File menu, choose Close
This closes the empty new project that Revit Building creates automatically upon launch
2 On the Standard toolbar, click the Open icon
o In the “Open” dialog box, browse to the location where you downloaded the dataset
3 Double-click BD13-2-Pavilion.rvt (You can also select it and then click the Open button)
The project will open in Revit Building with the last opened View visible on screen In this case that is the Level 1 floor plan View This
project has been started already and contains a Property Line object (dashed square in the middle of the screen) There is also a
Toposurface terrain model element in this file that represents the site for the building Let’s start by displaying this so we know where to place the Walls of our building
BEGIN A NEW MODEL
To get started, we need to begin with the basics: Walls, Doors and Windows These elements are the basic building blocks of any
architectural model Adding these elements in Revit Building is simple and straight forward
Create an Underlay
On the left side of the screen running vertically is a panel named: Project Browser In it are listed several representations of our project
including drawings, schedules and sheets Four floor plans are provided here: Level 1, Level 2, Site and Roof The first floor plan View Level 1 is bold indicating that it is currently active and open on screen
1 On the Project Browser, double-click to open the Site plan View
Notice that the Site Plan includes contours and a shape in the middle of the plan representing the building footprint and its entrance patio
o On the Project Browser, double-click to return to the Level 1 floor plan View
We can display any of the other floor plan Views (such as the Site View) as an underlay to this View to help us coordinate elements at
different levels
2 On the Project Browser, right-click on the Level 1 Floor Plan View and choose Properties (see Figure
1)
Trang 4
Figure 1 Edit the Properties of the Level 1 Floor Plan View
Figure 2 Assign the Underlay as the Site plan View
3 In the “Element Properties” dialog, beneath the “Graphics” grouping (near the bottom) click the word None next to “Underlay.”
o Open the pop-up menu that appears and then choose Site (see Figure 2)
o Click OK to dismiss the dialog and see the results
Notice that only the patio and building footprint outline appeared This is because they are the only parts of the Site that intersect the current level height (more on this later) Notice that they appear in 50% halftone gray as well This reinforces visually that this is simply an underlay
Create Walls
We begin our building model with some simple Walls
Locate the Design Bar on the left side of the screen The “Basics” tab should currently be active
4 On the Design Bar, click the Basics tab and then click the Wall tool
Several options will appear across the bar at the top of the screen just beneath the toolbar icons This is the Options Bar
5 From the drop-down list on the left (know as the Type Selector) choose Basic Wall : Generic - 8"
o From the “Loc Line” list, choose Finish Face:Exterior
o On the right side of the Options Bar, click the rectangle icon (see Figure 3)
Figure 3 Pick the Wall tool and set it to draw Basic 8" Walls in a rectangular shape
6 With the mouse pointer (now shaped like a small pencil) click the lower right corner of the gray shape on screen (see the left side of Figure 4)
Figure 4 Click the start of the Walls
o Pick the Endpoint of the short horizontal edge indicated on the right side of Figure 4
You will now have four Walls on screen However, the “room” they define is very narrow We can easily adjust this Before we can manipulate the Walls however, we must cancel the current Wall creation command
Trang 57 On the Design Bar, click the Modify tool or press the ESC key twice
Either method can be used anytime in Revit Building to cancel the current command and return to the Modify (selection pointer) tool
8 Click on the vertical Wall on the left to select it
In Revit Building objects turn red on screen when they are selected
9 Click the mouse directly on the blue text of the dimension that appears between the selected Wall and the other vertical one (see Figure 5)
Figure 5 Click the text of a temporary dimension to edit it
Figure 6 Draw a Wall in random location in the space
10 In the text field that appears, type 20 and then press ENTER
Notice that the Wall moved to the new location as indicated by the value we input and that the two horizontal Walls stretched with it to remain attached Please note that when you edit this way, the selected Wall moves The dimensions that we used for this edit are referred to
as “temporary dimensions.”
11 On the Design Bar, click the Wall tool again
o From the Type Selector choose Basic Wall : Generic - 5"
o From the “Loc Line” list, choose Wall Centerline
o Draw a vertical wall from top to bottom of the room approximately one third the width (see Figure 6)
Note: The exact dimensions are unimportant at this point, we will move the Wall next
o Beneath the temporary dimension, click the small icon (indicated in Figure 6) to make the dimension permanent
o On the Design Bar, click the Modify tool or press the ESC key twice
Now that the dimension is permanent, notice that it remains on screen when the Wall is no longer selected
12 Click to select the dimension
o Click the small “EQ” icon beneath the dimension (see Figure 7)
Figure 7 Toggle the Dimension Equality for the indicated Walls
13 From the File menu, choose Save
It is important to remember to save every so often to preserve your work Autodesk Revit Building is configured by default to remind you
to save at regular intervals You can edit the interval, but if the message asking you to save appears, you should always perform the save
Trang 6BD13-2—The Basics of Autodesk® Revit® Building 8.1 byPaul F Aubin
Insert Doors and Windows
Next we’ll add some opening to our Walls
14 On the Design Bar, click the Basics tab and then click the Door tool
o Accept all of the defaults on the Options Bar
o Move the pointer near the top horizontal Wall to begin placing the Door
Move the mouse around without clicking it yet Notice how the Door follows the cursor and also stays attached to the Wall as it does Also
notice that moving the mouse from one side of the Wall to the other will flip the Door in or out relative to the Wall The gray underlay we
added above indicates a patio shape to the left of the plan and wrapping around the top Our first door will be out to that passageway along
the top
15 Position the mouse on the top Wall near the right side of the passageway so it swings out and then click
(see Figure 8)
Figure 8 Place a Door to the outside near the passageway
Figure 9 Use the flip controls to change the Door orientation
16 Place another near the top of the interior vertical Wall
Notice that Door tags have automatically appeared and the numbers have filled in sequentially Sometimes you place a Door and it is not
positioned or oriented the way you like Just like the Walls above, we can select a Door, and then edit its temporary dimensions to move it
to the desired location There are also small flip control icons on the Door to control its orientation
17 Click the Flip control to change one of the Doors orientations (see Figure 9)
Repeat if desired on the other Door
Adding Windows works the same way as adding Doors
18 On the Design Bar, click the Basics tab and then click the Window tool
o Accept all of the defaults on the Options Bar
o Move the pointer near the top horizontal Wall and move up then down
Again notice how this controls the placement orientation of the Window As with the Door, you can always flip it later if you make an
error
19 Place Windows in the two horizontal Walls only (see Figure 10)
Let’s place one more Door in the Wall at the left This one we will load from an external library however
20 On the Design Bar, click the Basics tab and then click the Door tool
Trang 7o On the Options Bar, click the Load button
o Navigate to the Autodesk Web Library\Doors sub-folder of the folder where you installed the Mastering Autodesk Revit Building CD ROM files
o Select Double-Glass 2.rfa and then click Open
o Place the Door in the center of the left Wall swinging out Use the temporary dimensions to assist you
in placement (see Figure 11 – previous page)
o On the Design Bar, click the Modify tool or press the ESC key twice
21 Save the project
WORKING IN OTHER VIEWS
We can work in many types of Views in Revit Building; not just floor plans Our project includes elevation Views and ceiling plan Views already We can also add section Views and 3D Views Many other View types are also available and discussed in future chapters View the Model in 3D
Opening a three-dimensional View will reveal that our Wall height could use adjustment
1 On the Project Browser, double-click to open the West elevation View
o On the Project Browser, double-click to open the {3D} 3D View
This is the default three-dimensional View in Revit Building You can modify it as you like or create others from it We will use this one in
this tutorial, but make some simple adjustments to its vantage point Notice that the {3D} View is an isometric view of our building model
We can see the Walls, Doors and Windows we added from a bird’s eye vantage point We also see the Toposurface terrain model that was included in this project from CD You can change the vantage point of a 3D View interactively on screen
2 On the View toolbar, click the Dynamically Modify View icon (You can also press F8 instead)
A “Dynamic View” toolbox will appear in the lower left corner of the screen
o Click the Spin button
o Drag the mouse in the View window to spin the model around interactively
Drag side to side to move around the building
Drag up or down to change height of the vantage point
o Spin the model around so that the front double Door is visible (see Figure 12 – next page)
There are two other buttons on the “Dynamic View” toolbox, one to zoom (move closer or farther away from the model) the other to scroll which would slide the model View around on screen without changing the viewing angle like Spin does
o Close the “Dynamic View” toolbox
Create a Section View
Let’s open one more View of the model before we proceed This will allow us to understand the relationships built into our Revit Building model very clearly as we make some simple edits The View that we want to study does not exist yet We are going to cut a section through the model and look at that View next
3 On the Project Browser, double-click to open the Level 1 floor plan View
4 On the Design Bar, click the Basics tab and then click the Section tool
o Click to the left of the double Door
Move through the model to the right keeping the section line horizontal
o Click outside the model to the right (see Figure 13 – next page)
Trang 8
Figure 12 Dynamically Modify the {3D} View window
Figure 13 Cut a section through the model
A section line, with section head and tail will appear A section box with drag handles will also appear The Section Head will currently be red indicating that it is selected
5 Click next to the section line be careful not to click on any geometry
This is a quick way to deselect the selected element(s) You can also just press ESC twice Notice that the Section Head now turns blue
This indicates that it has a linked View associated to it Take notice of the Project Browser There will now be a Sections category
included in the list Revit Building creates nodes in the Project Browser like this one as required
o Double-click the blue Section Head to open the associated View
You should now see the Section 1 View on screen We now have four Views open If you click on the Window menu, you will see all
open Views listed near the bottom of the menu You can choose them off this list to bring them to the front of the pile, or you can simple double-click the View name in Project Browser again to display them You can also tile them all on screen at once Let’s do that now
6 From the Window menu, choose Tile (see Figure 14)
Figure 14 Tile the Views on screen to view them all at once
Edit in any View
Take a look at the elevation and section Views in particular This project has been set up to have two stories plus a roof Currently our Walls only go up one story and in fact they do not coincide with the second floor level at all Let’s fix both problems
7 Click in the floor plan View, Level 1 to make it active
8 Place your mouse pointer (the Modify tool) over one of the exterior Walls
Notice the way that it highlights under the cursor If you move the mouse without clicking, it will no longer highlight This is called “pre-highlight” and is a useful aid to proper selection
o Pre-highlight one exterior Wall—do not click yet
o Press the TAB key
Notice how all of the exterior Walls now pre-highlight
Trang 9o Click the left mouse button to select the pre-highlighted elements
Notice how all four exterior Walls are now shaded red in all open Views
9 On the Options Bar, click the Properties icon (see Figure 15)
Figure 15 Click the Properties icon to access the “Element
Properties” dialog
Figure 16 Move the Level line with the temporary dimension
o In the “Element Properties” dialog, from the “Top Constraint” list, choose Up to level: Roof and then click OK
Notice how the Walls project up to the Roof Level line in all Views The Walls are now set relative to this Level in the project If we were
to change the height of the Roof Level, the Walls would also adjust accordingly Let’s try that now
Note: The section will likely not show the top of the Walls as it is currently cropped to
the first floor You can adjust this with the round drag control at the top of the section box Click the rectangular box surrounding the section Click and drag upward the small blue circle at the top edge of the box The Walls should show
10 Click anywhere in the West elevation View
Zoom In Region to get a better look if you need to (right-click to access Zoom In Region)
o Click to select the second floor Level line
Notice the temporary dimensions that appear Like the Walls and other elements drawn so far, we can edit the blue dimension value to move the Level lines to a new location We will move both Level 2 and the Roof level; starting with Level 2
o Click the blue text of the temporary dimension between Level 1 and Level 2, type 10 and press ENTER (see Figure 16)
o Repeat for the Roof—select the Roof Level line
o Click the blue text of the temporary dimension between Level 2 and Roof, type 10 and press ENTER Notice that not only does the Roof Level line move, but since we constrained the Walls to the Roof Level, the top edge of the Walls adjusts
as well!
Move a Window
When you make an edit in a Revit Building model, the edit can be made in any View that you find convenient The edit will automatically
be applied to all Views This is the power of Autodesk Revit Building! You are describing a single virtual building model You can “view”
it in an unlimited number of ways Regardless of where you make the edit—plan, section, elevation or 3D, all Views are completely
coordinated
11 Spin the 3D model View to show the Windows on the north Wall
12 Select the Window on the north Wall
o Click on the titlebar of the plan View, then the section View
Not only is the Window highlighted red in all Views, but in each of these orthographic Views where it is visible, the temporary dimensions appear
o Edit the temporary dimension values to move the Window
Notice how it moves instantly in all Views You will never have to worry about chasing down a change in several different drawings to be
certain that it has been coordinated This will boost productivity and help reduce costly change orders
Align a Window
Trang 10BD13-2—The Basics of Autodesk® Revit® Building 8.1 byPaul F Aubin
At this point you may wish to line up the Window on the North Wall with the one on the South You can do this and have Revit Building
maintain the relationship with the Align tool
13 Click the Align tool on the Tools toolbar
You first indicate the point of reference We’ll use the Window we just moved
Click near the center of the Window you just moved to set the point of alignment
Click near the center of the opposite Window to align it to the reference point (see Figure 17)
Click the lock icon to constrain the alignment of the two Windows together
On the Design Bar, click the Modify tool or press the ESC key twice
If you now move either Window, they will move together
Move and align additional Windows in the same way if you wish
Add Openings on the Second Floor
Now that our Walls project up the height of both floors, we should add some fenestration on the second floor
14 On the Project Browser, double-click to open the Level 2 floor plan View
o Following the procedures above, add Windows and a Door to Level 2 as shown in Figure 18
Tip: You can select Windows on Level 1, choose Copy to Clipboard from the Edit menu, and
then Paste Aligned > Select Levels by Name and choose Level 2 from the dialog that
appears This will paste copies of the Windows in the same relative spots on Level
2 You can then move them if desired
Figure 17 Align the Windows
Figure 18 Add Doors and Windows to Level 2
ROUND OUT THE PROJECT
Our project needs more than just Walls, Doors and Windows Let’s enclose it with a Floor and Roof and look at how to extract data from
our model with Schedules
Add a Floor
The second floor will have a balcony on the right overlooking the space on the left
15 On the Design Bar, click the Basics tab and then click the Floor tool
When you click the Floor tool, the floor plan will turn gray The Design Bar will also change to include a series of “Sketch mode” tools
Sketch mode is a special mode in Revit Building used when the element that you are creating has a shape that Revit Building cannot easily
“guess.” In this case, it would not be possible for Revit Building to assume the size and shape of the Floor that we want, so instead, we
sketch it This is easy to do, given that we already have several Walls
On the Design Bars, the “Pick Walls” mode will be enabled as indicated my this button’s being selected
o Click one of the horizontal Walls, then the other
o Click the vertical exterior Wall on the right
