Clash Detection : Defining Touches and Clearances
These commands jointly define the tolerances that determine whether any given clash is reported as a physical clash, a touch or a clearance (see Figure 13:1.: Physical Clash, Touches and Clearances). MODEL reports a touch if two primitives either:
|
•
|
Overlap by less than a specified touch overlap distance
|
|
•
|
Are separated by less than a specified touch gap distance
|
The touch overlap setting must be positive: the touch gap must be positive and less than the current setting for the clearance distance. The default settings are for a touch overlap of 2mm and a touch gap of zero.
MODEL reports a clearance if two primitive volumes are separated at their closest point by more than the currently defined touch gap but by less than a specified clearance distance. The clearance distance must be positive and greater than the current setting for the touch gap. By default the clearance distance is undefined, so that no clearances will be found.
MODEL reports a clash if two primitives overlap by more than the touch overlap distance.
