I've been trying for a good 30 minutes now to simply snap a little object to a neighboring face, by following this simple explanation. Instead of going nuts I just thought I'd ask.
The result is never accurate, whatever I try: the smaller object always goes "through" the other mesh at an angle, rotates in every direction except the right one, etc.
I want the little piece to point outwards, with its largest flat face against one of the flat faces of the large shape - as in:
I've tried flipping normals, applying loc/rot/scale on and off, moving the origin of the object to the middle of the face I want it to snap to, tried every setting in the snap tools, but nothing helped.
What are the things to check when trying to snap an object to another, what am I missing?
