Review these tips and guidelines for creating extrusions.
- The work plane does not have to be either the start or the end of the extrusion depth. It is only used to sketch on and set the extrusion direction to be perpendicular to the plane.
- You can set the depth of the geometry before sketching it. In sketch mode, enter a value in the Depth text box in the
Modify | Extrusion ribbon panel. Depths can be negative values. The direction of positive and negative values are determined by the direction (z- axis) of the work plane where the sketch is created. If the extrusion goes in the opposite direction than expected, change the start and end values as required.
- You can modify the depth of the extrusion after creating it by selecting it and on the Properties palette, specify values for the start and end points. You can also resize the extrusion in a 3D view by selecting it and then dragging it to resize it.
- If specified, the end point value is not retained during creation of the extrusion. If you need to make multiple extrusions with the same end point, first sketch the extrusions, then select them, and then apply the end point.
