If measured or constructed plane features are drawn in the Graphic Display window, this registry entry determines how they are drawn when created.
This registry entry does not affect existing plane features or Auto Plane features.
Entry Name: DisplayOutlineOfPlane
Entry Type: Whole number representing the display type. It can take one of two values. 0 means the plane is drawn as a triangle. 1 means the plane is drawn as an outline. The default value is 0. The size of the drawn shape depends on the hit locations.
See the "DoNotDisplayPlane" entry to control whether or not newly generated plane features are drawn.
Use "ClassicStylePlaneDisplay" if you want to use the old way of displaying plane features.
