Hinge subassembly will not rotate in larger assembly

I created hinge.iam wherein the two "leaves" and the pin are partially constrained so that the "leaves" can rotate in the manner expected of a hinge.

However, when I place hinge.iam into a larger assembly, the whole hinge acts like a solid part and will not rotate.

I want to constrain one "leaf" to a cabinet and the other to a door, and have the door swing freely.

Can someone give me a clue what I am missing?

RMB on hinge sub and check "flexible"

Make the hinge Flexible.

If you already tried that then another constraint is keeping it from moving. Overconstrained.

The answer is to make it flexible. No IF's, AND'S, or BUT'S.

Is it the first part you dropped in so its grounded?

No, the cabinet body was first and is grounded. But when I made the hinge flexible, one of the leaves rotated but the other one behaved as if it were grounded.

I will check the hinge assembly and try to determine if it is overconstrained.

Is the one leaf grounded in the subassy?

It was indeed grounded in the subassembly. I'm still mucking about with it and will let you know what I find.

Well, I finally got it to work. Turns out there was a subassembly within the subassembly, and as soon as I made all the subassemblies flexible, the hinge started behaving hinge-like.

So you're right, flexible is the answer, no ifs, ands or buts. I just had to catch all the cascading assemblies and make them so.

Picard out. ^¿^
