Hi LM, it will be predictable when the sweep path is planar and the profile is on that same plane:





But in your case there with a non-planar path curve it will be hard to predict. So in that case it's better not to use "auto place" mode where you put the profiles off to the side of the path. Instead move the profile directly on the path curve and then it will use it from that position:





I do want to add in some controls in the future for controlling "auto place" mode better, probably something like a direction line showing on the profile and a matching direction line on the path that you could modify.
