Creo Mechanism Constraints Limit - Constraint Set Will Not Enable
I am using Creo Parametric 9.0 and I am setting mechanism constraints (Pre-Defined Constraint sets) to make a dynamic model.
Into A.asm, I want to assemble another assembly, B.asm, which has multiple components that should be able to move relative to each other. I have B.asm set up so there are a few mechanism constraints that limit the range of motion so the components are tied together somewhat, but are still able to move as they should (rotate, translate, etc.).
When I assemble B.asm into A.asm, I define multiple mechanism constraint sets (Pre-Defined sets) to constrain the parts of B.asm to parts of A.asm. This use of multiple constraint sets works really well until I get up to 8 different sets. Then, the last constraint set has its "Enabled" check box unchecked, so the set is Disabled. Whenever I click the check box to enable that last constraint, the constraint works fine and the B.asm connects in the model as it should--so there are no connection failures. But, after hitting the green check, the constraint set automatically disables, and when I edit the definition of B.asm, it shows the "Enabled" check box as unchecked.
Is there an inherent limit to how many constraint sets can go on an assembly? Why does this set not enable? Is there a way to get it to enable permanently?
