The Extrude Face mode creates perpendicular faces as volume is added or subtracted. Objects that can be modified include 2D planar objects, NURBS curves, and the planar face of any solid.
To add to or subtract from a solid in Extrude Face mode:
Click the Push/Pull tool from the 3D Modeling tool set, and then select Extrude Face from the Tool bar.
Click the desired planar face, planar object, or NURBS curve.
If needed, the Select Face dialog box opens to help select the correct face, as described in Selecting the Edges and Faces of a Solid. To select the back faces of solids, press the Alt key (Windows) or Option key (Mac) while selecting. When the correct face is selected, click OK.
The cursor changes to a double-headed arrow. Move the cursor to expand (Add mode) or decrease (Subtract mode) the solid volume, or create an extrusion from the 2D planar object or NURBS curve. The cursor direction determines whether volume is added or subtracted. The distance of the protrusion or cutout can also be specified by entering a value in the Distance field on the Tool bar or floating data bar. The new solid is previewed on the drawing.
Click at the desired location to edit the solid.
