Important variables for solids and surfaces

As in 2D, AutoCAD has also some variables responsible for the creation or visualization of 3D objects:

• ISOLINES: This variable controls the number of lines used to represent curved faces of solids with the wireframe visual style. These isolines should not be confused with edges. By default, its initial value is 4 and it is saved with the drawing.

• DISPSILH: This variable controls the display of silhouette edges of solids when applying a wireframe visual style. It is saved with the drawing and accepts two values, 0 (the silhouette is not displayed; this is the default) and 1 (silhouettes are displayed).

  

• FACETRES: This variable controls the amount of faceted faces used to represent shaded or rendered objects. All shaded or rendered views are calculated by faceting all curved surfaces and faces. By default, its initial value is 0.5 and it is saved with the drawing. Its value can go from 0.01 to 10; a reasonable value is 2 or 3.

  

• DELOBJ: This variable...
