HI Fusion team and users 🙂
You will add function place constraints like an inventor? i think is better than function assemble join
you will add function join to plane or axis? in Inventor i do easy ( create axis catch component and place contrains to axis.
Sorry for my english i am czech. i make elevator components from sheet metal in old inventor and fusion360 is not a same for me.
But it is my problem 🙂
