Note:
When Make Quadrilaterals is on, the
Decimation sett ing has no effect.
Quad S ize %—Determines the size of the
quadrilaterals as a percentage of the overall
Boolean object length.
Planar Edge Removal group
This option determines how the polygons on
planar faces are handled. Choose one of the
following:
•
Remove All—Removes all extra coplanar edges
on a face such that the face itself will define the
polygon.
•
Remove Only Invisible—Removes invisible edges
on each face.
•
No Edge R emov al—N o edges are removed.

The ProCutter Compound object lets you perform
specialized Boolean operations, primarily for the
purpose of breaking apart or subdividing volumes.
The results of ProCutter operations are particularly
suitable for use in dy namics simulations where an
object explodes or is shattered by impact with a
force or another object.
Following is a list of ProCutter features:
• Break apart a stock object into elements of an
editable mesh or into separate objects using
cutters that are either solids or surfaces.
• Use one or more cutters on one or more stock
objects at the same time.
• Perform a volume decomposition of a set of
cutter objects.

Procedure
To use ProCutter:
1.
Select an object to use as a cutter.
2. Activate the ProCutter comp ound object.
3. On the Cutter Picking Parameters rollout, click
Pick Cutter Object s, and then select additional
cutters.
4. On the Cutter Picking Parameters rollout, click
Pick Stock Objec ts, and then select objects to
be cut by the cutter objects.
5. In the Cutter Parameters rollout > Cutter
Options group, choose t he parts of t he originals
you wish to keep: Stock Outside Cutters, Stock
Inside Cutters, Cutters Outside Stock.
6. To get separate objects to manipulate or
animate, collapse the result to an Editable Mesh
(page 1–996) object and use the Explode tool set
to 180.0. Alternatively, use Auto Extract Mesh
and Explode By Elements, described below.
