Part VI: Using Advanced Techniques
- Using the Selection Filter set to filter Face selection (the default hotkey for this is
X), select all the faces of the leg. You can use window selection techniques to avoid
clicking each face. - Click the Delete Face button on the Surfaces toolbar, or access the command by
choosing Insert ➪ Face ➪ Delete from the menus. Make sure that the Delete and Patch
option is selected. The selected faces and the Delete Face PropertyManager should look
like Figure 26.27. Click OK to accept the feature.
FIGURE 26.27
The Delete Face PropertyManager- Repeat the process for a second leg, leaving the third leg to be separated from the
rest of the part and patterned. - After the two legs have been removed, click the outer main spherical surface, and
then choose Insert ➪ Surface ➪ Offset from the menus. Set the offset distance to zero.
Notice that a Surface Bodies folder is now added to the tree, near the top.
Tip
A zero distance offset surface is frequently used to copy faces. n
- Hide the solid body. You can do this from the Solid Bodies folder, from the
FeatureManager, or from the graphics window. - Hiding the solid leaves the offset surface, and there should be three holes in it.
Select one of the edges of the hole indicated in Figure 26.28 and press the Delete key.
The Choose Option dialog box appears. Select the Delete Hole option rather than the
Delete Feature option. The Delete Hole operation becomes a history-based feature in the
model tree. Before moving on to the next step, remember that you may need to turn off
the Selection Filter for faces.
