Preface
The Version 5 Part Design application makes it possible to design precise 3D
mechanical parts with an intuitive and flexible user interface, from sketching in an
assembly context to iterative detailed design. Version 5 Part Design application will
enable you to accommodate design requirements for parts of various complexities,
from simple to advanced.
This application, which combines the power of feature-based design with the flexibility
of a Boolean approach, offers a highly productive and intuitive design environment
with multiple design methodologies, such as post-design and local 3D
parameterization.
As a scalable product, Part Design can be used in cooperation with other current or
future companion products such as Assembly Design and Generative Drafting. The
widest application portfolio in the industry is also accessible through interoperability
with CATIA Solutions Version 4 to enable support of the full product development
process from initial concept to product in operation.
The Part Design User's Guide has been designed to show you how to create a part.
There are several ways of creating a part and this book aims at illustrating the
several stages of creation you may encounter.

Preface
The Version 5 Part Design application makes it possible to design precise 3D mechanical
parts with an intuitive and flexible user interface, from sketching in an assembly context to

to design complex parts. You can also take a look at the sections describing the Part Design
Workbench at the end of the guide.
To perform the scenarios, you will use sample documents contained in the C:\Program
Files\Dassault Systèmes\B12doc\online\prtug\samples folder.
When samples belong to capabilities common to different products, those samples will be
found in the C:\Program Files\Dassault Systèmes\B12doc\online\cfyug\samples
folder.

New Functionalities
Solid Combine
This new command lets you create a solid by computing the intersection of two or
more virtually extruded profiles.
Remove Faces
Faces of different types can be removed in order to make parts more simple prior to
computing finite elements for example.

Customizing
Customizing General Settings
The "Delete Referenced Sketches" option has been renamed as "Delete exclusive
parents". Now, when this option is checked, the Delete dialog box inherits this setting:
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.http://pop.dia.uniroma3.it/catia/online/prtug_C2/prtugwn.htm (2 of 2)10/18/2004 7:43:40 PM

Creating a Pad
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.
Open the GettingStarted1_R04.CATPart document to open the required profile.
Your profile belongs to Sketch.1 and was created on plane xy. It looks like
this:
1.
Select the profile if not already selected and click the Pad icon .
The Pad Definition dialog box appears. Default options allow you to create a
basic pad.

2.
As you prefer to create a larger pad, enter 60 mm in the Length field.
The application previews the pad to be created.
3.
Click OK.
The pad is created. The extrusion is performed in a direction which is normal

Enter 9 degrees in the Angle field.
