Home / Cimatron Help / Delta/Reference


Extrude on one or both sides, a closed sketch / composite curve, 3D face or face with tolerant edges , by a given value and direction.

Important: Extrusions created by New > Extrude will be considered independent objects. Those created by Add > Extrude will be added to the active object. (If only one object exists in the file it is automatically active unless manually deactivated.) See Activate / Deactivate and Activating Objects.


Required Step 1

Pick the entity to be extruded (pick a closed 2D composite curvesketch or face).


  • If you enter Extrude immediately after creating a closed 2D composite curve or sketch, the entity is automatically included in Step 1.
  • If you select a sketch that contains more than one closed curve sequence, all closed curve sequences will be extruded. In order for a sketch to be selected, however, it must contain only closed curve sequences.pt23

Required Step 2

Set the extrusion parameters and the direction. The following parameters are displayed:

The default direction is normal to the 2D contour or sketch plane. You can flip the direction by clicking the displayed arrow head or body, or you can click on the arrow origin to set another direction.pt24

Delta/Reference This is a dropdown list of the available Extrude options.
One Side This is a toggle option: One Side / Both Sides:

One Side Extrude on one side of the contour.


Both Sides Extrude on both sides of the contour. The parameter settings for each extrude side are displayed under their respective Primary Side and Secondary Side headings (for more information on these headings, see Additional Delta/Reference Notes and the labeling rules below). This option is useful in Die tools, where, in many cases, it is necessary to create the punch (for example, to a reference) and also to define a delta to the other side.



By Delta This is a toggle option: By Delta / By Reference:

By Delta Extrude by a delta value. This option displays the Delta parameter; set this parameter to define the extrude distance.


By Reference Extrude to a reference entity (datum plane, face or object). This option displays the Offset from Reference parameter; set this parameter to define an offset distance from the reference face/plane.

If the reference entity is a planar face, the toggle option As Plane / As Object is displayed. See the As Plane / As Object notes below.


Invert Active Object Use the Invert Active Object option as required.

Optional Step 1

If you want to add a draft angle to the extrusion, see Defining a Draft Angle.


Optional Step 2

Change the active object (temporarily).

Press exit when finished. Or, if this is the final result, press OK  or Apply  in the Feature Guide to complete the function.

When completed, the Extrude feature will appear in the Feature Tree as follows:pt25
