SECTION (Command)

Uses the intersection of a plane with 3D solids, surfaces, or meshes to create a 2D region object.

The SECTION command creates a region object that represents a 2D cross section of 3D objects, including 3D solids, surfaces, and meshes.

This method does not have the live sectioning capabilities that are available for section plane objects that are created using the SECTIONPLANE command.

The following prompts are displayed.

Select objects

Selects one or more 3D objects. Selecting several objects creates separate regions for each object.

Specify the first point on the sectioning plane using one of the following methods:

  • Object
  • Z Axis
  • View
  • XY
  • YZ
  • ZX
  • 3points
Object

Aligns the sectioning plane with a circle, ellipse, circular or elliptical arc, 2D spline, or 2D polyline segment.

Z Axis

Defines the sectioning plane by specifying a point on the sectioning plane and another point on the Z axis, or normal, of the plane.

  • Point on the section plane. Sets the first point on the plane.
  • Point on the Z-axis (normal) of the plane. Specifies a point that defines the axis that is perpendicular to the plane.
View

Aligns the sectioning plane with the viewing plane of the current view.

XY

Aligns the sectioning plane with the XY plane of the current UCS.

YZ

Aligns the sectioning plane with the YZ plane of the current UCS.

ZX

Aligns the sectioning plane with the ZX plane of the current UCS.

3points

Uses three points to define the sectioning plane:
