Checking Interferences of 3D Solids

Use the Interfere command to check interferences within a solid model. The command prompts for two sets of either 3D solids. It tests each object of the first set with each object of the second set for a common volume.

If there are any existing interferences, you can

  • Create all new interfering 3D solids from the volumes that overlap.
  • Step through the highlighted display of pairs of 3D solids that interfere.

To check for interferences between two or more 3D solids:

  1. Click Solids > Solid Editing > Interference Checking (or type Interfere).
  2. Select the first set of solids and press Enter.
  3. Select the second set of solids and press Enter.
  4. If you define a single selection set, all 3D solids in the selection are checked against each other.
  5. If you define two selection sets, the 3D solids in the first set are checked against the 3D solids in the second set.
  6. If you include the same 3D solid in both selection sets, it is assumed that the object is part of the first set and is ignored in the second set.
  7. Specify whether you want to create interference 3D solids from the common volume of two or more 3D solids.
  8. Specify whether you want to highlight pairs of interfering 3D solids that overlap.
  9. If you want to highlight pairs of interfering 3D solids, use Next to cycle through the pairs of objects.

Note: The command keeps the original objects intact in contrast to the modifying commands performing Boolean operations on 3D solids.
