Section and Slice

May 20, 2011

You can section or slice a three dimensional solid.

Section

     You can create a region using the intersection of solid objects and a plane with the SECTION command. After selecting objects, the system creates a region on the current layer and inserts them into the location of the section.


Methods to define a section:

  • Specifies three points to define a sectioning plane.

  • Align the sectioning plane with a circle, ellipse, arc, 2D spline or 2D polyline object.

  • Specifies a point lied on the sectioning plane and a point lied on the normal of the defined section.

  • Align the sectioning plane with the plane of the current view.

  • Specifies a point to determine the location of the sectioning plane on the XY, YZ or ZX plane, and aligns the sectioning plane with the XY, YZ, or ZX plane of the current UCS.


To section an object

  1. Choose Draw > Solids > Section.

  2. Select the objects to cross section.

  3. Do one of the following:

  • Specify three points to define the cross section plane. (The first point defines the origin,while the second point defines the x axis and the third point defines the y axis.)

  • Type o and press Enter to select an object that defines the cross sectional plane.

  • Specify an axis by typing Z and pressing Enter.

Slice

You can use SLICE command to slice a solid with a plane and retain the specify part or the entire solid. The sliced solids retain the layer and color's properties of the original ones. To slice a solid, you have to define a cutting plane, then select which part to retain.


Methods to define a cutting plane:

  • Specifies three points to define a cutting plane.

  • Align the cutting plane with a circle, ellipse, arc, 2D spline or 2D polyline object.

  • Specifies a point lied on the cutting plane and a point lied on the normal of the defined section.

  • Align the cutting plane with the plane of the current view.

  • Specifies a point to determine the location of the cutting plane on the XY, YZ or ZX plane, and aligns the cutting plane with the XY, YZ, or ZX plane of the current UCS.


To slice a solid

  1. Choose Draw > Solids > Slice.

  2. Select the objects to slice.

  3. Do one of the following:

  • Specify three points to define the cross section plane. (The first point defines the origin,while the second point defines the x axis and the third point defines the y axis.)

  • Type o and press Enter to select an object that defines the cross sectional plane.

  • Specify an axis by typing Z and pressing Enter.

  1. Specify which side to retain, or type b to retain both sides.
