Asymmetric (extrude in two directions with different values) Enter a value for the positive distance. Enter a second value for the negative distance.
To Next Click the direction of the extrusion.
To Click a sketch point, work point, model vertex, work plane, or the End termination surface.
Between method Click the start and end termination surfaces.
Note: For To and Between extents If termination options are ambiguous, such as on a cylinder or irregular surface, to specify direction, click More > Flip. By default, the extrusion terminates on the maximum-distance surface. To terminate on the nearest-distance surface, click Minimum Solution.
All Click the direction of the extrusion, or to extrude equally in both directions.
On the More tab, enter a taper angle, if necessary. In the graphics window, an arrow shows the taper direction. When you use Distance-Distance, you can apply a taper angle to both directions.
