Using the Dragger
When you select surfaces and click > > , the dragger is attached to the geometry to be moved.
Drag the centerpoint to freely move geometry. Drag a handle to translate geometry along an axis. Drag an arc to rotate geometry. Drag a plane to move the geometry on the plane.
1. Centerpoint
2. Handle
3. Arc
4. Plane
To change the move reference planes, select a different surface on the model to position the dragger. Use the dragger to move geometry relative to the new references.
