Creating a Plane on an existing plane

Creating a plane on an existing plane can be useful in a number of situations. For example, you might need to create a particular section of a solid based on a certain existing plane. You can obtain the section by creating a plane parallel to the existing plane and through a point of the solid and then by cutting the solid along the plane using the Cut Solid command.

2 Select the existing plane.



To change the selected plane, right-click on Plane in the selection list, select Reset in the context menu and perform selection again.
