I'm doing a ducting layout as an assembly and I've setup my ducting pieces to have magnetic mates at the end of each piece (pictured below is the setup):
For most of my layouts, using the "ground plane" is great however sometimes the elbows need to be a different rotational angle (eg. ducting goes up into the rafters), below is a gif of my attempt at this problem (I used an elbow without a defined ground plane below):
I created a plane 45 degrees to the top plane and was hoping the elbow would just rotate but no bueno. Does anyone have any thoughts? After I find a solution for this problem I hope to write a macro that allows quick parallel mating between planes and selections. Thanks all.
