Menu Path: Modify > Extrude

Description

The Extrude command is an effective way of adding new geometry to an object by essentially pulling or extending faces or edges out of the model. In edge selection mode, Extrude creates a new copy of the selected edges, and connects each new edge to the original with a face. The new edge will then be selected, allowing you to move or otherwise edit it as desired. In face selection mode, new faces are similarly created for the boundaries of the selection, allowing you to pull out the selected faces from the original object.

The extrude amount can be controlled interactively using the tool manipulator or numerically in the options dialog. Pressing Enter or right-clicking will complete and exit the tool.

Options

Default Amount

Determines how much to offset the extrude when the command is called. When used with the tool already active, it is equivalent to dragging the manipulator handle for this command to the specified value, and allows you to enter precise values for the current operation. This amount will also be applied each time you use the command in the future. Set it to 0 if you want no default adjustment.

Extrude Faces Together

If this option is checked, selected faces which are neighbors will be extruded as a whole, rather than individually.

Sticky Functionality

Press and hold the keyboard shortcut for this command to temporarily enter the tool, and move your mouse to adjust the amount. Release the shortcut to exit the tool. This allows you to model more quickly since you do not need to manually exit the tool.
