The two major differences between separate SET and just one more constraint is :
1. If you use Mechanism Connections you need to add New Set. So if you have Planar and want to add Pin you go to New Set.
2. ProE / Creo has an individual control for activating / deactivating separate constraint SET (we do not have it per single constraint). This control happens through component parameter PTC_CONSTRAINT_SET. Parameter appears for each component that gets more than one set created.
Usages are several :
- control parameter by relations / pro/program - as a result component will switch from one placement set to another.
- vary active sets throughout Family Table - by adding this parameter. SO that for INST1 it may be SET1, for INST2 it may be SET2 etc.
Valid input for this parameter is an existing set name (or names, coma separated).
