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
CHAMFEREDGE
command is used to create chamfers on 3D objects. Additionally, the
CHAMFER
command can be used to chamfer 3D objects. 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.
A chamfer is applied to a 3D object by selecting an edge to chamfer. Just as when
chamfering a 2D line, there are two chamfer distances. An edge is actually the intersec-
tion of two surfaces of the solid. Therefore, the fi rst and second distances correspond
to two surfaces on the solid. The surface associated with the fi rst chamfer distance is
called the base surface.
Once the
CHAMFEREDGE
command is entered, select an edge to chamfer. Then,
enter the
Distance
option to set the chamfer distances. See Figure 8-21. A preview of
the chamfer appears, allowing you to adjust the distances. You can continue to select
edges on the same face or enter the
Loop
option. The
Loop
option is similar to the
Loop
option used with the
FILLETEDGE
command and allows you to select a loop of edges.
