I am unsure when "Auto Placement" of the profile occurs.
Can there be a version of sweep with "Auto Placement" turned off?

Sweeping a circle or arc with its center selected...
Sweeping a circle or arc, with a point on the arc, or off of the arc, but on the unused extension of the arc...

Iss Auto Placement and Auto orientation turned off in some situations?
