Setting Advanced Clearance Checking
You can control the calculation accuracy used for clearance checks.
The system's default method of clearance checking is to check for a local minimum at random points. You can specify a slower but more accurate method of checking for clearance and distance measures, whereby the system computes the high quality first guess based on refined triangulation. With this method, the system facets the surfaces of the model (with a quality that is proportional to the configuration file option value setting), and checks for a local minimum at each triangle point.
To perform more accurate analysis on pairs clearance, use the clearance_triangulation configuration file option settings:
• none—checks for a local minimum at random points (the default)
• low—corresponds to a 7 x 7 minimum grid on a surface
• medium—corresponds to a 14 x 14 minimum grid on a surface
• high—corresponds to a 21 x 21 minimum grid on a surface
• highest—corresponds to a 35 x 35 minimum grid on a surface

These settings affect performance and may not be acceptable for very large assemblies. Clearance interference calculations using these settings take 50 to 150 times longer than default clearance checking calculations.
