Using This Guide

This book is intended for the user who needs to become quickly familiar with Part Design

product The user should be familiar with basic Version 5 concepts such as document

windows, standard and view toolbars

To get the most out of this guide, we suggest you start reading and performing the

scratch

Once you have finished, you should move on to the next sections dealing with the handling

of CATPart data, then the creation and modification of various types of features you will need to construct parts This guide also presents other Part Design capabilities allowing you

When samples belong to capabilities common to different products, those samples will be

Where to Find More Information

Prior to reading this book, we recommend that you read the Infrastructure User's Guide and the Dynamic Sketcher User's Guide.

Other complementary product guides such as the Assembly Design User's Guide, the

Wireframe and Surface User's Guide, the Generative Drafting User's Guide and the Product Knowledge Template User's Guide can prove useful too

What's New?

It is now possible to make all the features of a body or part body publicly available.Creation Contextual Commands

Contextual commands for creating wireframe and surfacic elements, commands such

as "Create Line", "Create Plane", but also "Create Join", "Create Extrapol" or "Create Extract", "Create Intersections", "Create Projections", "Create Boundary" are now available from diverse existing capabilities:

❍ "Pad not normal to Sketch Plane", "Up to Plane Pad", "Up to Surface Pad"

❍ "Edge Fillet", "Face-Face Fillet" (Limiting Elements), (Spine), (Hold Curve), "Variable

Radius Fillet" (Points), (Limiting Elements), "Tritangent Fillet"

❍ "Draft Angle" (Pulling Directions), (Limiting Elements), "Variable Angle Draft" (Points),

❍ "Rectangular Pattern", "Circular Pattern", "User Pattern"

Customizing General Settings

The "Delete Referenced Sketches" option has been renamed as "Delete exclusive

the Delete exclusive parents option is active in the Delete dialog box as well

Customizing the Tree and the Geometry Views

A new option lets you customize the display of the geometry of the current body only

A new option lets you define the size of axis systems in mm

Getting Started

Before getting into the detailed instructions for using CATIA Version 5 parts, the following tutorial aims at giving you a feel as to what you can do with the product It provides a step-by-step scenario showing you how to use key functionalities

The main tasks described in this section are:

Entering the Part Design Workbench

Creating a PadDrafting a FaceFilleting an EdgeEditing the PadMirroring the PartSketching a Circle from a Face

Creating a PocketShelling the Part

All together, the tasks should take about ten minutes to complete

The final part will look like this:

Now, let's get to sketching the profile!

Creating a Pad

This task will show you how to create a pad, that is extrude a profile sketched in the

Sketcher workbench For more about this workbench, please refer to Dynamic

Sketcher User's Guide Version 5.

Your profile belongs to Sketch.1 and was created on plane xy It looks like this:

The Pad Definition dialog box appears Default options allow you to create a basic pad

Trang 18

Creating a Pad

The application previews the pad to be created

The pad is created The extrusion is performed in a direction which is normal

to the sketch plane The application displays this creation in the specification tree:

Trang 19

Creating a Pad

The application lets you control the display of some of the part components

To know more about the components you can display or hide, refer to

Trang 20

Drafting a Face

Drafting a Face This task will show you how to draft a face

The Draft Definition dialog box appears The application displays the default pulling direction on the part

The application detects all the faces to be drafted The selected face is now in dark red whereas the other faces are in a lighter red

The neutral element is now displayed in blue, the neutral curve in pink

Filleting an Edge

In this task you will learn how to use one of the fillet commands designed to fillet edges

1 Click the Edge Fillet icon

The Edge Fillet Definition dialog box appears It contains default values

2

Select the edge to be filleted, that is, to be rounded

Clicking Preview lets you see what the default fillet would look like

3 Enter 7 mm as the new radius value and Click OK

Here is your part:

Editing the Pad

Actually, you would like the pad to be thicker This task shows you how to edit the pad, then how to color the part

You can do it in the specification tree if you wish

The part is modified accordingly

Mirroring the Part

show you how easy it is

Trang 28

Mirroring the Part

Trang 29

In this task, you will learn how to:

● sketch a circle on an existing face

● use this circle in order to create a pocket

Trang 30

For more about Sketcher elements, please refer to Dynamic Sketcher User's Guide Version 5.

Trang 31

Creating a Pocket

In this task, you will learn a method to create a pocket using the profile you have just created

The Pocket Definition dialog box is displayed and the application previews a pocket with default parameters

The application will limit the pocket onto the last possible face, that is the pad bottom

Trang 33

Shelling the Part

To end the scenario, you will learn how to shell the part

The selected face turns purple and the

Shell Definition dialog box appears

You have defined a positive value, which means that you are going to obtain a thin part thickness

Basic Tasks

The basic tasks you will perform in the Part Design workbench are mainly the creation of features and surfaces you will use to create your part To create features you will

sometimes sketch profiles first or use existing features

This section will explain and illustrate how to create various kinds of features and surfaces The table below lists the information you will find

The Part Design workbench document is divided into:

● the specification tree

● the geometry area

● specific toolbars : for information, please refer to Part Design Workbench

a number of contextual commands available in the specification tree and in the geometry Remember that these commands can also be accessed from the menu bar

You will notice that the application provides three planes to let you start your

design Actually, designing a part from scratch will first require designing a sketch Sketching profiles is performed in the Sketcher workbench which is fully integrated

plane of your choice

The Sketcher workbench then provides a large number of tools allowing you to

sketch the profiles you need For more information, refer to CATIA-Dynamic

Sketcher User's Guide Version 5.

Sketch-Based Features

Features are entities you combine to make up your part The features presented here are obtained by applying commands on initial profiles created in the Sketcher workbench (See CATIA-Dynamic Sketcher User's Guide Version 5 ) or in the Generative Shape Design

workbench (See CATIA Generative Shape Design User's Guide Version 5) as well as surfaces

Some operations consist in adding material, others in removing material In this section, you will learn how to create the following features:

parameters you need in the dialog box

or Pocket dialog box and select the Go to Profile Definition contextual command to display the Profile Definition dialog box

the Type option to `Up to next' and enter the parameters you need in the dialog box

Type option to `Up to last' and enter the parameters you need in the dialog box
