Slice

Works with Bricscad (Windows) Pro

Cuts a 3D solid with a plane; the result is a 3D solid cut in two.

Accessing the Command

command bar: slice

alias: sl

menu bar: Draw | 3D Entities | Slice

toolbar: Solid |

: slice

Prompts you in the command bar:

Select entities: (Choose one or more 3D solids.)

Entities in set: 1

Select entities: (Choose more 3D solids, or press Enter to continue.)

Specify first point on section plane or Object/Zaxis/View/XY/YZ/ZX: (Enter an option.)

Specify a point on the current view plane <0,0,0>: (Pick a point, or enter x,y,z coordinates.)

Specify a point on desired side of the plane or Both: (Choose one of the parts; the other one is erased. Or type B to retain both.)

The sliced solid can be separated and its two parts manipulated as independent entities:

Command Options

Option	Description
Select entities	Specifies the entities that will be sliced. Choose one or more 3D solids; this command does not work with 2D regions.
Specify first point on section plane	Specifies the first of three points that define the slicing plane. Pick a point or enter x,y,z coordinates; prompts you: Specify second point on plane - pick another point. Specify third point on plane - pick a third point.
Object	Slices the 3D model with an entity that intersects the 3D solid; prompts you: Select a circle, ellipse, arc, 2D-spline, or 2D-polyline - choose an entity. You can also use elliptical arcs. The entity defines the plane that slices the 3D solid.
Zaxis	Slices the 3D model with a plane defined by one point on the plane, and a second on the plane's normal (z axis); prompts you: Specify a point on the section plane - pick a point to define the location of the section plane. Specify a point on the Z-axis (normal) of the plane - pick another point to locate the normal.
View	Slices the 3D model with a plane defined by the current 3D viewpoint; prompts you: Specify a point on the current view plane - pick a point to define the height of the plane. This is probably the easiest of the options.
XY	Slices the 3D model with a plane parallel to the x,y plane; prompts you: Specify a point on the XY-plane - pick a point to define the height of the slicing plane above or below the x,y plane.
YZ	Slices the 3D model with a plane parallel to the y,z plane; prompts you: Specify a point on the YZ-plane - pick a point to define the height of the slicing plane above or below the y,z plane.
ZX	Slices the 3D model with a plane parallel to the z,x plane; prompts you: Specify a point on the ZX-plane - pick a point to define the height of the slicing plane above or below the z,x plane.

Specify a point on desired side of the plane or Both	Specifies which of the two portions to keep. Choose one of the parts; the other one is erased. Or type B to retain both parts.
