Extrude > Remove: Delta/Reference

Access: Open this function from one of the following locations:

Click the button in the toolbar.
Select Solid > Main Tools > Extrude from the menu bar.
Select Extrude on the popup menu if a sketch or 2D composite curve is selected.
Select Die Design > Insert Tools > Extrude from the menu bar.
Select Mold Design > Insert > Extrude from the menu bar.
Select Insert > Extrude button in the Mold Design Guide Toolbar or Parting Guide Toolbar.

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

In this option, extrude either by Delta (extrude on one or both sides, by a given value and direction) or by Reference (extrude to a reference face or plane).

Important: When using this function, material will be removed only from the current active object. (If only one object exists in the file it is automatically active unless manually deactivated.) See Activate / Deactivate and Activating Objects.

Note: For Add and Remove operations you can use wires or faces from a non-activated component (external reference).

Required Step 1

Selected entity.

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.

By Delta

This is a toggle option By Delta / By Reference. This option is displayed if the Delta/Reference option is selected above.

By Delta

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

By Reference

Extrude to a reference entity (datum plane, face, object, curve(s), edge(s) or sketch(es)). This option displays the Offset from Reference parameter; set this parameter to define an offset distance from the reference face/plane.
Example:Example:

Pick the reference face/plane.	The contour is extruded to the reference entity.

Add Example showing the results of the Offset from Ref. parameter:Add Example showing the results of the Offset from Ref. parameter:

Pick the reference face/plane.	The contour is extruded to the reference entity.


Offset from Ref. = 0
Offset from Ref. = <positive value>
Offset from Ref. = <negative value>

The planar or non-planar attributes of the reference geometry determines the options that are displayed.
If the reference entity is a planar or non-planar face, in both cases the toggle option Extend / Don't Extend is displayed.
For non-planar faces: If the Extend option is selected, an additional toggle option Natural / Tangent is displayed.

See the Planar / Non-Planar Reference Face Options.

To extrude to both sides of the entity to be extruded, toggle One Side to Both Sides. The following parameters are displayed:

Toggle One Side to Both Sides to extrude to the desired position on either side.

One Side result:	Both Sides result:
