Moving faces linearly resembles the 2-D stretch command. When the face(s) is moved, the neighboring faces grow until they meet the modified face or other faces. The Move 3D command consists of two major requirements:
Single Face - Typically results in lengthening or shortening of the part.
Multiple Faces - Like the image, this step offers an easy way to lengthen a part with design features at the end.
Internal Faces - These are pockets that need to be altered or holes that need to be realigned.
Traditional translation - Methods include 2-points and direction-length.
3D CoPilot - This is an intuitive way of defining direction and length. Direction can be based on the initial arrows that appear, or can be referenced from any 3-D geometry. The distance can be determined by moving the mouse, typing, or snapping to faces (cursor over the desired face). The CoPilot also offers reference cones such that the references of the transformation can be changed. Not changing the reference will display a simple offset. Like the image, changing the source reference enables the feedback to display the overall length of the part instead of the offset.
