Extrude in NX Modeling

You can extrude the sketches, curves, and face edges to create a solid body or sheet body in the NX modeling. Also, Extrude command is used to edit created bodies by adding, removing, and partitions

The figure shows the location of the “Extrude” command on the “Home Ribbon Bar”. Also, you can use the shortcut “X” to start the “Extrude” command.

Creating or Editing solid-body by using the “Extrude” command:

1. Start the “Extrude” command.
2. Select sketch to extrude. (“Select Curve” in the “Section” group is active.)
3. The extrude direction will be perpendicular to the selected sketch. If you want to change the extrusion direction, Click twice on the arrowhead or click on the “Reverse Direction” icon in the “Direction” group.
4. Specify the methods and limits for starting and ending surfaces.
5. Click “Ok” or the middle mouse button to create a solid body.

Methods to Limit extrude start-end surfaces

1. Value: Specifies the start-end of the extrude by using distances. You can type the extrude start-end distance values or drag the arrowhead or arrow start point to specify distances.
2. Symmetric Value: Creates extruded body on the symmetric distance on both sides of the start
3. Until Next: extrudes to the next surface.
4. Until Selected: Extrudes to the selected surface. The projection of the section should be inside the selected surface.
5. Until Extended: Extrudes to the selected surface. The projection of the section can be outside of the selected surface. NX extends the selected surface to the path of the extrusion automatically.
6. Offset from Selected: You can specify the distance value to the selected surface.
7. Through All: Extrudes the section through the body. Mostly used for subtracting from the body.

Boolean Methods in the “Extrude” command:

1. None: Used for creating the first body in modeling. Also, you can use it for creating new bodies in the part modeling.
2. Unite: Used for adding extrusion to the created body.
3. Subtract: Used for removing extrusion from the created body.
4. Intersect: Creates body on the intersection of the created body and extrusion.
