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
Polylines (including spline-fit polylines, rectangles, polygons, boundaries,
and donuts)
Text (only if created as a single-line text object using an SHX font)
Points
Modifying the thickness property of other types of objects does not affect
their appearance.
You can set the default thickness property for new objects you create by setting
the THICKNESS system variable. For existing objects, change the thickness
property on the Properties Inspector palette.
The 3D thickness is applied uniformly to an object; a single object cannot
have different thicknesses.
You might need to change the 3D viewpoint to see the effect of thickness on
an object.
NOTE Although the THICKNESS variable sets an extruded thickness for new 2D
objects, those objects continue to be 2D objects. The THICKEN command adds
volume to a surface object, converting it to a 3D solid.
