FIxed components on an assembly still move

Hi,
if I make an assembly (all parts fixed) and insert it into another, I still can move the components of the first assembly (that has became a sub-assembly) one relate to other, is it right? Normally in other CAD system when you insert a sub assembly, you can't move sub-components of the sub-assembly, where am I wrong?

Hi @michele_cavallerin
Looks like you may have already figured this out. When inserting a sub-assembly into another assembly, all "fix"es are removed. It wouldn't be useful if these "fix"es were kept, because then you couldn't position your subassembly within the main assembly, it would just be fixed in the same place as it was in the other assembly tab. The recommended workflow here is to just "fix" one part in the subassembly and apply a "group" mate to hold all the parts in position. Then, when you bring the grouped subassembly into the main assembly, it will continue to move together.

still have an issue about this; if I insert an assembly inside one other, why can't I fix the first one as I know this is a static frame?

In any case still I don't get the reason of this, but maybe it's just because this is different from other CADs.
Regards.
