Wireframe Shading Methods

The Wireframe Properties screen is used to format the appearance of wireframe overlays in 3D windows.

These options determine the rendering method used to display wireframe data.

	Shading Mode	Comments
	Points	Display the current wireframe as vertex data only. This data is held in the "wireframe points" file, typically ending with a "pt" suffix prior to the file extension.
	Wireframe	Display only the wireframe edges.
	Flat	Shade wireframe triangles distinctly and individually.
	Smooth	Interpolate (dither) the shading between wireframe triangles.
	Highlighted Edges	A combination of Smooth and Wireframe modes.
	Intersection	Display the cross-section of the wireframe with the current (active) section, or the Intersection Section, which can be any loaded section definition.
	Intersection (filled)	If Intersection is selected, you can fill intersection outlines with Fill intersection. This also caps the ends of wireframe data that has been clipped in the view.
	Unlit	Available for Flat and Smooth modes, if Unlit is checked, a solid colour (no environmental lighting) is used to render the wireframe data.
