Extrude a polygon face, edge, or vertex

You can add polygons to an existing mesh using the Extrude feature ( Edit Mesh > Extrude). You can extrude polygon faces, edges, or vertices using the feature. For example, when you extrude a face on a polygon mesh the existing face telescopes inwards or outwards as it creates new connecting faces on the sides of the extrusion.

To extrude polygon faces or edges

1. Select the faces or edges you want to extrude.
2. Select Edit Mesh > Extrude

   The action creates an extrude node and switches to the Show Manipulator Tool.

3. Do any of the following:
   • Use the manipulator to control the direction and distance of the extrusion. Remember that you can also change the pivot by pressing Insert or Home. Click the circle handle attached to the manipulator to switch between local and world axes.

     

     NoteThe Show Manipulator Tool only appears when Construction History is on.
   • Use the controls in the Attribute Editor or Channel Box to edit the extrusion. See Edit Mesh > Extrude.
     TipYou can scale and rotate the extrusion along its length to create interesting forms.
     NoteExtruding edges can make your mesh non-manifold. Use Mesh > Cleanup to fix non-manifold geometry.

To extrude edges or faces along a path curve

1. Select the edges/or faces you want to extrude and the curve you want to extrude along.

   

2. Select Edit Mesh > Extrude > .
3. Turn on the Use selected curve for extrusion option.
4. Click Extrude.

   

5. Use the controls in the Attribute Editor or Channel Box to edit the extrusion. See Edit Mesh > Extrude.

   For example, increase Divisions so the extruded polygons better match the shape of the curve.

   

   Reduce Taper so the extruded polygons gradually become narrower along the curve. (You can also use the Taper Curve controls to create more complex tapers.)

   

   Adjust Twist so the extruded polygons rotate along the curve.

   

Vertices extrude along its vertex normal, creating additional faces for each face that shares the vertex.

To extrude a vertex

1. Select the vertex you want to extrude.
2. Select Edit Mesh > Extrude > .
3. Set the Length setting to extrude the vertex and click Extrude.
