Offset functionality:
- Allows to add an offset to a selected set of shapes (surfaces or
volumes), this provides a security margin around these shapes.
- Enables to define the vectors along which the offset is applied.
These vectors are defined either from the product main axis system or
from any axis system in a .CATPart document (Part Design workbench, Axis
System command).

For more detailed information, please refer to
More about Offset along Fixed Vectors.
|
|
This task will show you how to generate offsets along fixed vectors
through the offset command. |
|
Open
mastervac_offset.CATProduct document |
|
Use the Fit All In icon
to position the model geometry on the screen. |
|
(Optional)
You can manage automatically your offset result
as alternate shape of the initial component. In this case, the offset
result will be automatically reinserted and will replace the initial
component (provided the Activate check box is selected, it is by
default)Note: If your are not working in
alternate shape mode, it is strongly recommended to use the Reference
Product option to avoid positioning problems when reinserting
products. Read About

-
Click the Offset icon
in the DMU Optimizer toolbar.
The Offset dialog box is displayed.
-
Select the solid or surface you want to work on (i.e.
MASTERVAC (MASTERVAC.1) in the specification tree or in the geometry
area.
-
Select the Along fixed vectors check box. The
along fixed vectors frame is no longer grayed out.
-
If necessary, click in the Axis system area and select
the axis system which defines the offset directions (the default axis
system is the product main axis system)
- i.e. select Axis System.1 either in the geometry area or in the
specification tree.

-
Enter the required offset values in the x, y and z
fields:
-
Click Preview to generate the offset
representation.
The Preview window is displayed:
-
Zoom to visualize better the offset result.
-
Click Save to save the result.
The Save As dialog box is displayed:
-
Enter a meaningful name and save in the desired format (.cgr,
.vrml or.CATIA model)
-
In our example, save your result MASTERVAC.1_OFFSET in
cgr format.
-
Click Close to exit the offset command

Alternate Shape:
(Optional)
You can manage automatically your Offset result as alternate shape of the
initial component.
For this:
- Select Tools->Options from the menu bar. The
Options dialog box is
displayed
- Expand the Digital Mockup category from the upper-left tree.
- Select DMU Optimizer item to display the corresponding tab.The
Alternate Shapes Management is available
- Select the Offset check box: the offset is automatically
activated as an alternate shape
The Offset result will be added to the initial component as a new
representation
For more details, please refer to Customizing DMU Optimizer Settings and
Managing as an Alternate Shape. |
