Extrusion


Extrusion is used to build mesh elements of plus one dimension than the input ones. Any line or planar element can be extruded. Line elements will extrude into quadrilateral plane elements. Triangular and Quadrilateral plane elements extrude into Pentahedron and Hexahedron solids respectively.

To use extrusion:

  1. From the Modification menu choose the Extrusion item or click "Extrusion" button in the toolbar.

    The following dialog common for line and planar elements will appear:

  2. In this dialog:

    • select the type of elements which will be extruded (0D, 1D or 2D),
    • specify the IDs of the elements which will be extruded:
      • Select the whole mesh, submesh or group activating this checkbox; or
      • choose mesh elements with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
      • input the element IDs directly in ID Elements field. The selected elements will be highlighted in the viewer; or
      • apply Filters. Set filter button allows to apply a filter to the selection of elements. See more about filters in the Selection filter library page.
    • If the Extrude to Distance radio button is selected
      • specify the distance at which the elements will be extruded,
    • If the Extrude Along Vector radio button is selected
      • specify the coordinates of the vector along which the elements will be extruded, or select the face (the normal to the face will define the vector)
      • specify the distance of extrusion along the vector,
    • specify the number of steps;
    • activate Generate Groups checkbox if it is necessary to copy the groups of elements of the source mesh to the newly created one.

  3. Click Apply or Apply and Close button to confirm the operation.
