SECTIONPLANE (Command)

Section plane objects create sections of 3D solids, surfaces, meshes, and point clouds. Use live sectioning with section plane objects to analyze a model, save sections as blocks for use in layouts, and extract 2D geometry from point clouds.

List of Options

The following options are displayed.

Face or Any Point to Locate Section Line

Specifies a face to establish the plane of the section object.

Alternatively, you can select any point on the screen that is not on a face to create a section object independent of the solid or surface. The first point establishes a point around which the section object rotates.

• Through point. Sets a second point that defines the plane of the section object.

Draw section

Defines the section object with multiple points to create a section line with jogs.

This option creates a section object in the Section Boundary state with live sectioning turned off.

Orthographic

Aligns the section object to an orthographic orientation relative to the UCS.

A section object that contains all 3D objects is created with the specified orientation relative to the UCS (not the current view). This option creates a section object in the Section Plane state with live sectioning turned on.

• Align section to. Sets the position of the section object to align with one of the following UCS orientations that you specify:
  • Front
  • Back
  • Top
  • Bottom
  • Left
  • Right

Type

Specifies a plane, slice, boundary or volume as the parameter when creating the section plane. Once you choose a style, the command reverts back to the first prompt, with the selected type set as default.

• Plane. Allows you to specify a planar segment of a 3D solid, surface, mesh, or point cloud and place the section plane.
  
• Slice. Allows you to select a planar segment with depth of a 3D solid, surface, mesh or point cloud to place the section plane.
  
  Note: The slice cannot contain any jogs and the draw selection option is disabled.
• Boundary. Allows you to select the boundary of a 3D solid, surface, mesh, or point cloud and place the section plane.
  
• Volume. Allows you to create a bounded volume section plane.
