Solid Edge V12 Assembly / Circulary Dependency
Solid Edge V12 Assembly / Circulary Dependency
(OP)
I use Solid EDge V12
I working on a 30-40 pieces assembly
When i would like to ad a relationship between 2 part, i recived this error message
Relationship Conflict
This contraint would create a circular dependency and is not allowed
If someone what can i do to fix this problem, because i didn't find anything on the SE help and my SE resaler don't know what to do,
thanks

RE: Solid Edge V12 Assembly / Circulary Dependency
When I work on the parts of an assembly, their features change. Sometimes the constraints will become invalid because of the changes.
i.e. Add draft to a part, on face that is used for a constraint. Since the part can't "tilt" in the assembly (due to the other constraints), all the constraints become invalid.
Generally, if the assembly doesn’t have moving parts, I might not make the corrections right away because the part is likely in the same place (or the change might not be permanent).
So, down the road, when I try to add a new part, SE returns an error (not always, but sometimes).
It doesn't matter what kind of constraint I use or which parts I constrain to--even constraining to the layout planes yields the same error. Which is weird, because the layout planes are the base "parts" of an assembly and, theoretically, there is nothing you could do to mess them up.
I found that to fix it, you need to correct or remove all invalid constraints. Use the To Do List to help.
On a related note, when you have invalid constraints, the Move Part tool greys out.

As fwc stated, the typical cause of circular dependancies is inter-part copies. For example, you have holes in Part B that you want to match in Part A so you interpart copy Part B into A. You then go into the assembly and try to locate Part B relative to A using those features created in A from the interpart copy of B.
