How to make the 3d manipulator act parallel to a plane How would i be able to set my 3d manipulator so that one of the axis is parallel to the face of what im moving, i want to move it parallel to the face of the plane.
Select (a face in) the plane
Create a Custom Orientation (CtrlAltSpace)
(Check 'Use after creation' and possibly 'Overwrite previous' in the tool region,if you don't want to bother to name the orientation, and/or don't need it later)
Any translation you now make with G-ShiftZ-ShiftZ will be parallel to the plane you selected.
