Delta Mid Plane

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.

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.

Required Step 1

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

Notes:

  • 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.po1

Required Step 2

Press the Delta = field to enter the extrusion value. The value you enter is the total extrusion depth – the contour is extruded by half the value in each direction. The default direction is normal to the 2D contour or sketch plane; you can click on the arrow origin to set another direction. (In this case, flipping the arrow direction has no effect.)po2

Use the Invert Active Object option as required.

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

The results can be better seen in Top view. Note that extrusion value specified is the total extrusion length.po4

 

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).

 

When completed, the Extrude feature will appear in the Feature Tree as follows:pe15
