Element: graphic_window.depth_clipping
Element: graphic_window.depth_clippingnumeric
The state of entity clipping in the Z axis for graphic_window. Many applications are 2-D only and therefore need no clipping along the Z axis during rendering.
Setting this attribute to 0 (no Z clipping) can improve rendering performance. For new windows, its initial value is 1 and should be left unchanged when entities have valid Z co-ordinates and horizontal sectional views are required.
