Define Collision Groups

Under Group 1 and Group 2, use the criteria interface to define the collision groups.

• To check collisions between all element types, use the same criteria for both groups.
• To check collisions between 3D elements and MEP elements only, limit one of the groups to elements classified as MEP.
• To use a saved Criteria Set to define a Collision Group: Click the Criteria Set Name arrow to list the project’s criteria sets:

  
  
  

  • If you pick a Criteria Set here, its contents will overwrite the Collision Group’s current criteria
  • Listed Criteria Sets may be disabled if the set includes criteria not applicable to Collision Detection (e.g. 2D element types, or IFC properties)

    See also Predefined Criteria Sets.

• Click Add to bring up a dialog to choose any Properties and Parameters by which to limit the group.
