Assembly: Different offset constrain for each copy of part

[astromedia]

Hi,
I have two parts - one that is unique and one that I did make one copy of and I did used offset constrain on one of those to offset it by some value from the unique part and now when I want to do this with the second copy it tells me Im overconstraining despite selecting different copy than for my previous offset ... I suppose its somehow limited per original object instead of instance for some reason? I dont get why.

From what you write it appears that there is some constraint already applied to your second part.
I would delete it and then right click on the first selecting insert duplicate.
You will get a second copy with no constraints on it.

Can I check? I hope that "make one copy of" doesn't mean you copied the file in Windows....

I did made copy initially (context menu: insert duplicate) and constrains later one by one. Its weird behavior ... here is image:


Both item 1 and item 2 have only one offset constrain from its appropriate face to the profile appropriate face ... on one part its valid, on second its overconstrain :/ ... its worth noting the copy has for some reason different child items (yellow) - maybe thats relevant?

What's inside InterDesign Relations? Are you mating to parts or the assembly? I see Face so that is a InterDesign Relation? That could be the cause.

There was like 30 things, I tryed to clear it on mass to see what happens but that did not worked, then I did deleted the only red one and now everything there is gone and my constrains seems to work now so I guess its solved, thanks. (Hopefully without any side consequences ... I have still a lot of blank spaces in how all that works ... I guess it was somehow generated while I was moving the part or so before)

A thing to watch out for is that at times duplicate parts are made anchored. I don't know the conditions that cause this, but if there are constraint problems check that no parts that shouldn't be are anchored.
(Many people anchor the initial part of an assembly. I never anchor, but position even the first part with constraints. As such in my assemblies any anchored part is an error of some kind.)
