Creates new 3D solids and surfaces by slicing, or dividing, existing objects.
Summary
The cutting plane is defined with 2 or 3 points, by specifying a major plane of the UCS, or by selecting a surface object (but not a mesh). Either one or both sides of the sliced 3D solids can be retained.
The sliced objects retain the layer and color properties of the original solids. However, the resulting solid or surface objects do not retain a history of the original objects.

List of Prompts
The following prompts are displayed.
Objects to sliceSpecifies the 3D solid or surface object that you want to slice. If you select a mesh object, you can choose to convert it to a 3D solid or surface before completing the slice operation.
Start point of slicing planeSets the first of two points that define the angle of the slicing plane. The slicing plane is perpendicular to the XY plane of the current UCS.
- Second point on plane. Sets the second of two points on the slicing plane.
Planar objectAligns the cutting plane with a plane that contains a selected circle, ellipse, circular or elliptical arc, 2D spline, or 2D polyline segment.
- Select a circle, ellipse, arc, 2D-spline, or 2D-polyline. Specifies the object to use for alignment.
SurfaceAligns the cutting plane with a surface.
- Select a surface. Specifies a surface to be used for alignment.
Z axisDefines the cutting plane by specifying a point on the plane and another point on the Z axis (normal) of the plane.
- Specify a point on the section plane. Sets a point on the slicing plane.
- Specify a point on the Z-axis (normal) of the plane. Specifies a point that defines the axis that is perpendicular to the slicing plane.
ViewAligns the cutting plane with the current viewport's viewing plane. Specifying a point defines the location of the cutting plane.
- Specify a point on the current view plane. Sets a point on the object to start the slice.
XYAligns the cutting plane with the XY plane of the current user coordinate system (UCS). Specifying a point defines the location of the cutting plane.
- Point on the XY-plane. Sets the location of the slice.
YZAligns the cutting plane with the YZ plane of the current UCS. Specifying a point defines the location of the cutting plane.
- Point on the YZ-plane. Sets the location of the slice.
ZXAligns the cutting plane with the ZX plane of the current UCS. Specifying a point defines the location of the cutting plane.
3pointsDefines the cutting plane using three points:
- First point on plane. Sets the first of three points.
- Second point on plane. Sets the second of three points.
- Third point on plane. Sets the third of three points.
Point on desired sideUses a point to determine which side of the sliced solids your drawing retains. The point cannot lie on the cutting plane.
Keep both sidesRetains both sides of the sliced solids. Slicing a single solid into two pieces creates two solids from the pieces on either side of the plane. SLICE never creates more than two new composite solids for each selected solid.
