Cutting objects

Sometimes we need to cut 3D objects. Here is a command to perform this task. The PROJECTGEOMETRY command (presented later in this chapter), although not being its main function, also allows cutting 3D objects.

Cutting solids and surfaces

Here is the most used command to cut solids and surfaces.

The SLICE command

The SLICE command (alias SL) allows cutting solids and surfaces by a plane or an existing surface. We can maintain both parts or select one. We can also access this command on the ribbon, Home | Solid Editing, and on the Menu Bar, Modify | Solid Editing.

We start the command by selecting the objects to cut:

Command: SLICE
Select objects to slice: Selection

We have to define the cutting plane. By default, we define a vertical cutting plane, specified by two points:

Specify start point of slicing plane or [planar Object/Surface/Zaxis/View/XY/YZ /ZX/3points] <3points>: Point
Specify second point on lane: Point

Then, we specify a point to indicate which part we want...
