Hi Michael. I can't seem to replicate the non-expected behaviour in my example file, and my project file has been modified a lot since. I've had the issue a few times in the past, but the fact that I can't replicate it (the example part is now orienting to both the surface AND the surface snap points for positioning) would indicate there was something weird with my original geometry or process. Will try capture the problem in the future, if there is one! Thank you.
