To Specify the Cut Plane Elevation of a Structural Member Style
Use this procedure to specify the cut plane elevation of a structural member style. The cut plane settings you specify in the structural member style override the cut plane settings in any display configuration applied to a viewport.
Note: If the cut plane does not intersect the structural member, all visible and hidden components display. If the cut plane does intersect the member, only the cross section of the components of the structural member displays. These are the actual member shapes unless you select True Cut Body.
