I find it very confusing that when using the Draw/Imprint on Solid tool I have to constrain the profile of my imprint to the surface I'm trying to attach it tooin 3 axis. X &Y relative to profile normal makeI understand but I don't constrain Z to the face and variables change in just the right way my imprint flips to another face. I find this confusing when in reality I would assume most users are trying to attach the profile to a face of the solid not the solid as a whole.
