Using the Implicit Plane Tool

This three-dimensional widget defines an infinite plane that can be interactively placed in a scene. The widget is represented by a plane with a normal vector; the plane is contained by a bounding box. The intersection edges of the plane and the bounding box are shown tubed.

The normal vector handle can be selected and moved to rotate the plane; the plane itself can be selected and translated in various directions.

The scale of the bounding box is set automatically to the combined size of the input parts that you select for the plane.

The widget can be picked even when it is "behind" other actors. This is an intended feature and not a bug.

If you select the normal vector, you can rotate the plane arbitrarily. You can also translate the plane along the normal by clicking and dragging.

You can arbitrarily move the plane origin by clicking and dragging the plane with the middle mouse button.

You can constrain the translation of the plane by ticking the Snap to Part option in the Plane Parameters group box, and selecting the part in the drop-down menu. This makes it easy to align a plane with a certain part.

To refine the plane's position, you can adjust the coordinates with text entries. After each text entry, press <Enter> to apply your adjustment.
