Section and Slice 3D Solids
With SECTION, you can create a cross section through a solid as a region or
an anonymous block. The default method is specifying three points to define
the plane. Other methods define the cross-sectional plane by another object,
the current view, the Z axis, or the XY, YZ, or ZX plane. AutoCAD places the
cross-sectional plane on the current layer.
With
SLICE, you can create a new solid by cutting the existing solid and
removing a specified side. You can retain one or both halves of the sliced
solids. The sliced solids retain the layer and color properties of the original
solids. The default method of slicing a solid is to specify three points that
define the cutting plane and then select which side to retain. You can also
define the cutting plane by using another object, the current view, the Z axis,
or the XY, YZ, or ZX plane.
To create a cross section of a solid
1 From the Draw menu, choose Solids ➤ Section.
2 Select the objects to cross-section.
3 Specify three points to define the cross-sectional plane.
The first point defines the origin (0,0,0) of the cutting plane. The second
point defines the X axis, and the third point defines the Y axis.

Note If you are applying hatching to the cross-sectional cutting plane, you
must align the UCS with the cross-sectional cutting plane first.
