You can construct and edit solid models while the object is displayed in a shaded view.
If your computer has suffi cient speed and power, it is often much easier to visualize
the model in a 3D view with a shaded visual style set current. This allows you to real-
istically view the model. If an edit or construction does not look right, just undo and
try again.
Chamfering Solid Objects Chamfering Solid Objects
A chamfer is a small square edge on the edges of an object. The
CHAMFER
command can be used to create a chamfer on a 2D or 3D object. Just as when cham-
fering a 2D line, there are two chamfer distances. Therefore, you must specify which
surfaces correspond to the fi rst and second distances. The feature to which the chamfer
is applied must be constructed before chamfering. For example, if you are chamfering
a hole, the object (cylinder) must fi rst be subtracted to create the hole. If you are cham-
fering an intersection, the two objects must fi rst be unioned.
After you enter the command, you must pick the edge you want to chamfer. The
edge is actually the intersection of two surfaces of the solid. One of the two surfaces
is highlighted when you select the edge. The highlighted surface is associated with
the fi rst chamfer distance. This surface is called the base surface. If the highlighted
surface is not the one you want as the base surface, enter
N
at the
[Next/OK]
prompt
and press [Enter]. This highlights the next surface. An edge is created by two surfaces.
Therefore, when you enter
N
for the next surface, AutoCAD cycles through only two
surfaces. When the proper base surface is highlighted, press [Enter].
