Interference AIM Overview

One can build and place components (Bodies) parametrically and if done correctly then no single Body penetrates another. This cannot always be accomplished, for example when a component is imported or the level of geometric complexity makes building in these constraints very difficult. Under these circumstances it is important to determine if the final placements of Bodies do not intersect.

This AIM takes a collection of Solid Bodies and returns the minimum distance found between Bodies (if not intersecting) or as a negative number, the penetration depth when the Bodies interfere. This is accomplished by using a discrete representation of the Bodies (using the EGADS tessellator) so the accuracy of the values returned is a function of how good of an approximation the tessellation is to the actual BRep.

An outline of the AIM's inputs and outputs are provided in AIM Inputs and AIM Outputs, respectively.
