System Variables
ELEVATION
Stores the current elevation of new objects relative to the current UCS.
FACETRES
Adjusts the smoothness of shaded and rendered objects and objects with
hidden lines removed.
ISOLINES
Specifies the number of contour lines displayed on the curved surfaces of 3D
solids.
Add 3D Thickness to Objects
Use the thickness property to give objects a 3D appearance.
The 3D thickness of an object is the distance that object is extended, or
thickened, above or below its location in space. Positive thickness extrudes
upward in the positive Z direction; negative thickness extrudes downward
(negative Z). Zero (0) thickness means that there is no 3D thickening of the
object.
The orientation of the UCS when the object was created determines the Z
direction. Objects with a non-zero thickness can be shaded and can hide other
objects behind them.
The thickness property changes the appearance of the following types of
objects:
2D solids
Arcs
Circles
Lines
