Hi all out there.

This may be a newbie question, but until now I couldn't find/guess a good answer.

I'm working on a rather complex multiple parts assembly (it must be an assembly due to movement analysis).

I'm trying to create a couple of reference sketches, in front and top planes, to drive dimensions and geometrical relationships between several parts of the same assembly.

The only solution I could find up to now is to create a part, with the two or three refernece sketches, each sketch in its corresponding plane, and then copy it as a start for every assembly part. It makes easier to modify, i.e. a distance between two axes, or the width of all related parts.

But the modifications have to be replicated in the same sketch of every concerned part.

I wonder if there is a more simple method to control such relationships,
