Manage automatically your result as an alternate shape.
For this:
- Select Tools > Options from the menu bar.
The Options dialog box is displayed.
- Expand the Digital Mockup category from the left-hand tree.
- Select DMU Optimizer item to display the corresponding
tab. The Alternate Shapes Management is available
- Select the Swept Volume check box: it is
automatically activated as an alternate shape. When activated the
swept volume representation is the one visualized in session.
|
|
Make sure your simulation or track is set to the beginning step
before launching the swept volume computation. |
-
Select the products to sweep. In our example, select the
battery track in the specification tree
-
Click Swept Volume
.
The Swept Volume dialog box is displayed.
-
(Optional) you
can also compute a silhouette before the swept volume. This is very
useful when handling large models as the silhouette operation removes
useless triangles.
-
Click Preview to obtain a preview.
The progress bar is displayed letting you monitor and, if necessary,
interrupt (Cancel option) the calculation.
|
|
Now you want to simplify the swept volume result, you are
going to reduce the number of triangles used to create the resulting
shape, first wrapping the swept volume and then applying a
simplification on the wrapping result. |
-
Select the Apply Wrapping check box
-
Set the grain by
entering a value. In our example, keep the default value 4mm
-
Set the Offset
Ratio. In our example, keep the default value
-
Click Preview
|
The number of triangles representing the wrapping result is
displayed in the Number of triangles field as shown below: |
|
-
Select the Apply Simplification check box (on
the wrapped swept volume)
-
Enter 0.2mm in the Simplification accuracy field
-
(Optional,
i.e. when dealing with a track presenting numerous positions or dealing
with a large digital mockup), you can select the Spatial Split
check box.
For more detailed information, refer to More about
the spatial split option.
-
Click Preview to launch the calculation. This
is what you obtain:
|
The number of triangles representing the
simplification result is displayed in the Number of triangles
field
as shown below:
The simplification representation is coarse but the number of
triangles has been drastically reduced. |
|
-
Click Save. The Save As dialog box
automatically appears
-
Select cgr file from the Save as type drop-down list,
enter a meaningful name and click Save.
-
Click Close to exit the Swept volume command
This is what you obtain: |
|
Your swept volume is managed as an alternate shape,
therefore, it is automatically inserted into your product and
replaces the original component (Battery.1) |
