NOTE NOTE
Once the
SLICE
command has been used, the history of the solid to that point is
removed. If a history of the work is important, then save a copy of the fi le or place a
copy of the object on a frozen layer prior to performing the slice.
Planar Object
A second method to create a slice through a 3D solid is to use an existing planar
object. Planar objects include circles, arcs, ellipses, 2D polylines, and 2D splines. See
Figure 8-25A. The plane on which the planar object lies must intersect the object to be
sliced. The current UCS has no effect on this option.
Be sure that the planar object has been moved to the location of the slice. Then,
select the
SLICE
command, pick the object to slice, and press [Enter]. Next, enter the
Planar Object
option and select the slicing path object (the circle, in this case). Finally,
specify which side is to be retained. See Figure 8-25B. Again, if both sides are kept,
they are separate objects and can be individually manipulated.

Slicing a solid by
picking two points.
A—Select two points
on the cutting plane.
The plane passes
through these points
and is perpendicular
to the XY plane of
the current UCS.
