Clearance Checks
Clearance between specific components of an assembly is important in many types of products. Typically such clearance checks are very common in electromechanical assemblies. The clearance requirements may originate from a variety of sources – electrical, thermal, etc. Typical CAD systems provide generic clearance checks which need to be executed for specified clearance value on the complete assembly or on a specific pair of components. However, clearance requirements are typically more complex and expressed more easily in terms of rules.
Interference Checks
It is important to ensure that there is no interference condition which can prevent proper assembly of the product. Interference conditions due to design representation (like threaded areas) must be ignored.
