Converts 3D geometry to a projected 2D representation.
FLATTEN creates a 2D representation of selected objects and projects them onto the current viewing plane. FLATTEN results in 2D objects that retain their original layers, linetypes, colors and object types where possible. You can use FLATTEN to create a 2D drawing from a 3D model, or you can use it to force the thickness and elevations of selected objects to 0.
