Being new to MOI, I'm slowly working through the video tutorials. This one - http://paqwak.com/?cat=5 - making a snowman, has some circles being drawn on the surface of the snowman to be extruded to form buttons (at 07.00mins). With On Surface Snap selected, I still can't seem to be able to keep the circle on the surface when using the Center method of drawing a circle, as the modeler does. I can do it with Three Point circles (below) but can anyone point out what I'm doing wrong with the former method? The large sphere to the right shows what is happening. Using V.2.
