Assembly Fully Constrained

[Yogesh.T]

Why am I not able to get rid of that squares in red? It says fully constrained with no assumptions. Am I missing something? All degrees are arrested and still I see the square next to part in asm tree.! FRUSTRATING!!! 🙂

The double box means that a model (-001) is a CHILD of something above it on the model tree that's not constrained.  Need to find/fix that issue first, and it'll fix the -001 and MAYBE even all the others.

Best of luck!

Everything above it shows fully constrained. All looks ok above it in the tree.

On occassion, a placement will "glitch" and will never show fully constrained. If I think this is the case, I will deleted all the constraints and recreate the constraints. Sometimes it works. Or, alternatively, delete the existing constraints and replace with intentionally different constraints. Last option is to delete existing constraints and FIX placement (not preferred tho)

I really don't think this is your problem because it shows the double box glyph, which means it's the reference to that is bad and not the placement itself, "child of packaged component"

Look at the components your bracket is constrained to see if any of those are packaged or not fully constrained, maybe within one of the groups or within one of the assemblies. It can be really frustrating, I agree.

I do not see the part A3423417-001 - is that within the group?

[Yogesh.T]

Actually Patriot and Stephen,

You both are correct. The asm component on which the bracket is mounted had subassembly that was not constrained (It was fix). All below now are constrained. I guess it is ok to keep the component assembled with box , but since a complex assembly you never know what will move when some update..: ). 

Lesson Learned: Ensure the subassembly you assemble the component to is fully Constrained.

RESOLVED and THANK YOU!!!

The three constraints for the parent part are:

Coincident - (2) surfaces

Coincident - (2) axis of the center holes

Oriented - (2) smaller diameter holes.

I know it says fully constrained, but try adding a fourth constraint - if you have (2) planes that are parallel that would prevent the part from flipping over. There is a possibility that the part could flip 180 degrees. Not sure if this is the answer, but it is a possibility.
