Tolerance Settings

Tolerance settings are used to define minimum clash tolerances or tolerance zone requirements around objects. You can isolate an object, and then preview the selected object to visualize and experiment with these settings.

The following table is a list of the available tolerance settings:

Setting Description
None Used to detect any geometric intersection.
Expand

Expands the geometry in all directions by the defined value.

  • Use a negative number to require a minimum Clash Tolerance. Negative a tenth of an inch will require a collision of a tenth of an inch or more before listing it as a Clash.

  • Use a positive number to establish a clearance zone around the object. Positive one foot will list any geometry within a foot of the object as a Clash.
Sphere Establishes a spherical Clash Tolerance or Clearance Zone.
Cylinder Establishes a cylindrical Clash Tolerance or Clearance Zone.

Steps

You must first select an object. The object selected represents all objects with the same Primary or Secondary Tag Value selected.
