Assembly Constraints Snowballing Errors

[DSNR]

I have a bunch of assemblies that are acting this way and I am not sure why.

I ahve built the parts and built the sub-assemblies with-out errors, once everything looks good I place the subassemblies into my top level assembly.

Everything still looks good with no errors.

I do a rebuild of the top level assembly and find 20 or so errors.

Most of the errors are bogus and editing the constraint with-out changing anything removes the errors, typicaly.

On a bunch of the sub-assemblies the error showed up in the top level assembly, so I edit the part only to find the constraint is relevant but with errors so I suppress it to remove the error. Save and go back to the top level assembly only to find there is another constraint error in the same assembly that I suppresed the constraint to remove the error. This goes back and forth between top level and sub-assembly till all constraints are suppresed or deleted for the sub-assembly. Then the same thing happens to another sub-assembly.

This is driving me crazy, the only solution that I have found is to delete all constraints and rebuild each sub-assembly with the same constraints that were initialy used.

How do I stop this snowball effect???????????????????

Hi! Could you send me the files so I can take a look?

Thanks!

I think I have it figured out...

For some reason I deleted a assembly constraint, re-constrained it in the exact same way and all the other constraint errors disappeared. Not sure why or how but it worked.

Thanks anyway, much appriciated!!!
