Vanishing constraints
Vanishing constraints
(OP)
Hi all.
We are having some problems with assemblies, where constraints are being "lost" when we open up assemblies, at various times.
I'm beginning to wonder if we should just "ground" all parts to avoid this.
Have any of you had a similar problem?
We are using Inventor 9, and Vault 4.0.
Thanks in advance,
tg

RE: Vanishing constraints
We are using Inventor 9, Vault 3.0. That hasn't happened yet. The only time I get something like that is when I replace a component that isn't exactually the same as the one I'm replacing.
Does Inventor give any error message?

We don't seem to be getting an error message.
Just unexpected results.
With all the possible parameters that may contribute to modeling problems. i.e. file versions, users unaccustomed to using Vault, Vault itself including all its "quirks", possibly inexperienced users, etc, it's really hard to determine what's really happening here.
This will be the subject of my next post, read on...

If we first save sub-assy's, then save the main assy, we are effectively saving the constraints as well.
Is this correct?

I'm willing to forego adaptativity to gain in stability, like a good old fashioned AutoCAD 2D layout.
Thanks again,

That being said there is another more advanced technique called skeletal modeling. I have some tutorials on this subject at my sites.
