Extrusion along a straight edge

(not using base point -or angles)
- -\image html straight_before.png -
The image shows a 1D path mesh, built on a linear edge, and the initial 2D mesh.
- -\image html straight_after.png -
The image shows the result of extrusion of two edges -(#1 and #2) of the initial mesh along the path. \n Node #1 of path mesh -has been selected as Start node.

Extrusion along a curvilinear edge

(with and -without angles)
- -\image html curvi_simple_before.png -
The image shows a 1D path mesh, built on curvilinear edge, and -the initial 2D mesh.
- -\image html curvi_simple_after.png -
The central image shows the result of extrusion of one edge -(#2) of the initial mesh along the path. \n Node #1 of path mesh has -been selected as Start node.

Extrusion of a 2D face along a mesh built on a wire

Extrusion of 2d elements along a closed path

- -\image html circle_simple_before.png -
The image shows a path mesh built on a closed edge -(circle).

The central image shows the result of extrusion of both faces -of the initial mesh. \n Note, that no sewing has been done, so, there are -six coincident nodes and two coincident faces in the resulting -mesh.

To use Extrusion along Path: -
    -
  1. From the \b Modification menu choose the Extrusion along a -path item or click "Extrusion along a path" button in the toolbar. - -\image html image101.png -
    "Extrusion along a path" button
    - -The following dialog will appear: - -\image html extrusion_along_path_dlg.png -

  3. There are two optional parameters, which can be very useful: - -
    4. - - -
  4. Click \b Apply or Apply and Close button to confirm the - operation. Mesh edges will be extruded into faces, faces into - volumes. The external surface of the resulting 3d mesh (if faces - have been extruded) is covered with faces, and corners with - edges. If the path is closed, the resulting mesh can contain - duplicated nodes and faces, because no sewing is done. -
