Extrusion

Extrusion is propagation of the selected base shape in a certain direction and by a certain distance.
The Result of the operation will be a GEOM_Object (edge, face, shell solid or compsolid).

To generate an Extrusion on an object in the Main Menu select New Entity - > Generation - > Extrusion

The following parameters and options can be defined in this dialog

  • Result name of the created resulting shape.
  • Base - the extruded object. It is possible to select in GUI several Base Shapes to make several extrusions (using Shift button).

  • Direction and distance can be defined in three different ways selectable with the radio buttons on top of the dialog box :

    • By the Vector and the Height of extrusion. TUI Command: geompy.MakePrismVecH(Base, Vector, Height, theScaleFactor = -1.0)

    • By the Start and End Point of the Vector (in this way you don't need to create it in advance). TUI Command: geompy.MakePrism(Base, Point1, Point2, theScaleFactor = -1.0)

    • By DX, DY, and DZ coordinates of the Vector. TUI Command: geompy.MakePrismDXDYDZ(Base, dx, dy, dz, theScaleFactor = -1.0)

  • Both Directions checkbox allows extruding the base shape both forward and backward. With this option scaling is not possible.
  • Reverse checkbox reverts the direction of the scaling vector. It is usable only if the direction and distance are set via a Vector and a Height.
  • Scale the face opposite to the base checkbox and Scale Factor field allow building the extrusion with scaled opposite base. Scaling is possible only for 1D and 2D bases.

  • Add thickness checkbox and Thickess field allow adding thickness to the created prism (only when extruding an edge or wire). By default the material is added on the outside of the generated pipe, but it is possible to Thicken towards the inside using the corresponding checkbox. TUI Command: geompy.Thicken(Shape, Thickness)

  • Advanced options: Preview - displays the resulting shape in the viewer before Apply command.

Our TUI Scripts provide you with useful examples of creation of Complex Geometric Objects.
