Creating extruded surfaces

You can create an extruded surface, which is a three-dimensional body that approximates the surface generated by extruding a path curve along a direction vector. You select the two entities that define the path curve and direction vector. The length of the direction vector determines the distance the path curve is moved along the direction vector. The extruded entity can be an arc, circle, line, or polyline. You can choose a line or open polyline as the direction vector. The resulting body consists of a series of parallel polygonal planes running along the specified path.

To create an extruded surface

  1. Advanced experience level
  2. Do one of the following:
    • Choose Insert > 3D Entities > Extruded Surface.
    • On the Draw 3D toolbar, click the Extruded Surface tool ().
    • Type tabsurf and then press Enter.
  3. Select the entity to extrude.
  4. Select the extrusion path.



Select the entity to extrude (A) and the extrusion path (B).

The resulting extruded surface mesh.

NOTE   An extruded body is different from an extruded solid. If you wish to extrude an entity and convert it to a three-dimensional solid, use the Extrude command.
