Creating Extruded Volumes

Volume Extrude lets you create a volume by extruding a profile along a given direction.


Before you begin: Create a 3D shape containing a surface.
  1. In the Profile box, select the profile to be extruded.
    Important: The profile must be closed and must not self-intersect.
  2. In the Direction box, specify the direction of extrusion.
    • You can select a line to take its orientation as the extrusion direction or a plane to take its normal as extrusion direction.
    • You can also specify the direction by means of X, Y, Z vector components by using the context menu in the Direction box.
    Important: The direction must not be tangent (locally or not) to the profile to be extruded.
  3. Specify the Limit Types of the extrusion.
    • Length: enter length values or use the graphic handles to define the start and end limits of the extrusion.
    • Up-to element: select a geometric element. It can be a point, a plane or a surface. If a point is specified, the up-to element is the plane normal to the extrusion direction passing through the given point.
    Note: The wires cannot be selected as an up-to element.
  4. Select Symmetric extrusion to extrude the profile in the opposite direction using the same dimension value as the one defined for the first dimension.
  5. Click Reverse Direction or the arrow in the work area to display the extrusion on the other side of the selected profile.
  6. Click OK to create the volume.
