Extruding in 2D to 3D You can extrude base features and other features using Convert to Extrusion (2D to 3D toolbar) with partial sketches. Extruded Boss/Base on the Features toolbar accepts only complete sketches. To extrude a feature: Edit a sketch. Select the sketch entities required for the feature. It is not necessary to select a complete sketch. Hold Ctrl and select a point (in any sketch) to be the starting point for the extrusion. If you do not select a starting point, or if you select a point in the edited sketch, the plane of the sketch is considered to be the starting point. Click Convert to Extrusion (2D to 3D toolbar), or click Tools > Sketch Tools > 2D to 3D > Extrude, and click in the graphics area to establish the direction of the extrusion. The Base-Extrude PropertyManager appears. Edit the properties in the Base Extrude PropertyManager. For 2D to 3D conversion, you can specify the depth of a blind extrusion by selecting a sketch entity. Click Depth and select an entity in a sketch. Click OK . Example of Extruding in 2D to 3D Conversion Select the sketch entities (in the Front sketch at the lower left) as the basis for the base extrusion. Hold Ctrl and select a starting point (upper left vertex in the Top sketch). Click in the graphics area to establish the direction of the extrusion. In the Base-Extrude PropertyManager, click Depth and select the line shown to specify the depth of the extrusion.
