About the Extrude Feature
Extrusion is a method of defining three-dimensional geometry by translating a two-dimensional sketch normal to the sketch plane, for a pre-defined distance or up to a specified reference. Use the Extrude tool to create a solid or surface feature, and to add or remove material. You can create the following extrusion types:
• Protrusion—Solid, Thickened
• Cut—Solid, Thickened
• Extruded surface
• Surface trim—Regular, Thickened
|
|
 In Assembly mode, you can only create a solid cut, surface, or surface trim. |
Activating the Extrude Tool
There are several ways to activate the Extrude tool:
• Click
Model >
Extrude and create a sketch to extrude. This method is referred to as action-object.
• Select an existing sketch and then click
Model >
Extrude. This method is referred to as object-action.
• Select a datum plane or planar surface to use as the sketching plane and then click
Model >
Extrude.
A preview of the feature is displayed in the graphics window. You can adjust the feature as needed by changing the extrusion depth, switching between a solid or surface, protrusion or cut, or assigning a thickness to the sketch to create a thickened feature.
Creating a Two-Sided Feature
You can create a two-sided feature that is constructed on both sides of the sketching plane, with a depth option defined for each side.
To create a two-sided feature, start creating an extrusion with a depth option defined for one side. Then click the Options tab, or right-click the graphics window or a drag handle, and define the depth option for the second side.
