Well, the arc commands are like other planar object drawing commands in that they want to draw the arc in a particular plane.

So if you want to use those commands you need to set the drawing plane to the orientation you want and then you can draw your desired result with the regular arc command.

Maybe in the future I'll be able to set up some drawing method for drawing on a curved surface making a kind of automatically projected result that adheres to the surface. Unfortunately it's kind of difficult to make that happen on just any kind of a surface with every kind of drawing tool without some kind of distortion happening in the drawn shape, and it might be kind of weird to say use the circle tool but get some kind of distorted result instead of a real circle. That kind of odd situation is basically why I haven't attempted to do that kind of thing yet.
