Thank you for the answer.
A simple example:
I built an assembly i.e. gearbox: primary shaft, small gear, big gear and secondary shaft. I have to build 4 Catpart, that I will assemble in a Catproduct with constraints (axis coincidence, shaft offset, gear offset, gear surface contact etc).
In this case I suppose it's necessary to publish all 4 Catpart to not loose constraints in case of geometry modification, i.e. gear diam or gear Z etc.
Many features of Catparts are involved in constraint. I need to select any line or palne or axis and publish separately or I can publish simply all 4 catparts? How publish the entire catpart?
Thanks
