Specifies the distance that the cross-section is offset from free edge or from the plate face.
If Position is set to On Face, then the offset is measured from the free edge. A positive offset value moves the cross- section towards the plate. A negative offset value moves the cross-section away from the plate.
If Position is set to On Edge, then the offset is measured from the plate face. A positive offset value moves the cross- section in the opposite direction from the primary orientation. A negative value moves the cross-section in the same direction as the primary orientation.
