Interferences are highlighted with a temporary 3D solid that represents the intersecting
volume. You can also choose to retain the overlapping volumes.

Pressing Enter starts the interference testing of pairs of 3D solids and displays
the Interference Checking dialog box.

The following prompts are displayed.

First set of objects

Specifies a set of objects to be checked. If you do not select a second set of objects,
all objects in this selection set are checked against each other.

Second set of objects

Specifies an additional set of objects to be compared against the first set of objects.
If you select the same object twice, the object is handled as part of the first selection
set.

Check

Check first set

Initiates interference checking for only the first selection set.

Nested selection

Provides access to individual solid objects that are nested in blocks and xrefs.

• Select nested objects. Specifies which nested objects to include in the selection set.
• Exit. Restores normal object selection (not nested).

Settings
