You can create a simple hole on a selected surface. You can adjust the depth and the diameter of the hole using the depth and the diameter draggers on the selected surface. When pulling the depth dragger, the hole is created with a blind depth. On the other hand, if you hold down the SHIFT key while pulling the dragger, you can snap the dragger to a surface, curve, or a point to specify the depth. You can flip the drill direction by pulling the depth dragger to the opposite side of the placement reference.
