I am having trouble with behavior in assemblies. Odd behavior with planar alignments and moving with the steering wheel. Where I used to drag my first part in and it became anchored with the origin of the part aligned with assembly zero I now have to align by referencing the XYZ origin planes. Circular alignment did not work at all. I am getting "The requested relationship conflicts with others and cannot be placed". Then it proceeds to not tell me why. Where is a good place to find out the differences and can I revert back to ST7 behavior for assemblies?
Hey, looks like I lost all my badges so welcome Dave the rookie
Hi Dave [the newb]
I tried to recreate your assembly issue, but I get the normally "grounded" first part by default, as expected....I can't recall where, & I had a look, but I can't find the setting that must be controlling this.....other than remembering there is a shorcut [hold shift] while placing your first part to suppress the automatic grounding function.
Perhaps this was the case for you......?

If the auto-ground function is not working for some reason (bound to just be a setting somwhere), the way to recreate it is to ground the part using the ground mate, then make sure the position XYZ and rotation XYZ of the part are all zero (in occurence properties).
Much simpler and easier than mating to the base planes etc.
I've only got ST7 here so can't try your specific example though occasionally this kind of thing happens to me too. To be honest, it's usually my fault, but also sometimes unexplainable.
I think there's probably a clash between a face mate and the cylindrical mate you're trying to do, i.e. it thinks the axis of the cylinder is not exactly perpendicular to the flat faces so it can't solve. As I said, sometimes I find I've made a stupid mistake in the modelling and sometimes it's unexplained, so either use the angle measurement tools to check your work, or place the cylindrical mate first, then do the face mates.
I sometimes think there's maybe a rounding error internal to SE that causes this, but I've no actual evidence for this!
Hold SHIFT & drag part in to skip adding relationships.
Hold CTRL & drag part in to force a 0,0,0 grounded position.
