Extrude

Pro, Platinum Pro, Platinum Pro, Platinum

Extrudes 2D entities to 3D solids.

Accessing the Command

command bar: extrude

alias: ext

menu bar: Model | 3D Solids | Extrude

toolbar: 3d Solids |

: extrude

Prompts you in the command bar:

Select entities: (Choose one or more closed 2D entities.)

Entities in set: 1

Select entities: (Choose more entities, or press Enter to continue.)

Specify height of extrusion or Path: (Enter a number, pick two points to show the height, or type P.)

Specify angle of taper for extrusion <0>: (Enter a number, or pick two points to show the angle.)

Any closed 2D entity can be extruded, including regions.

The resulting entity is a 3D solid.

Depending on the value of the DELOBJ (Delete Entity) system variable, the defining entities are either retained or deleted or you are prompted whether to keep or delete the source entities.

Command Options

Option	Description
Select entities	Specifies the entities to be extruded. Choose one or more 2D closed entities. This command produces 3D solids. The source entities are erased from the drawing.
Specify height of extrusion	Specifies the height of the extrusion (3D solid): Enter a number - specifies the height; enter a negative number to extrude downwards. Pick a point - specifies the height; you are prompted: Second point - pick another point in the drawing. Entities are extruded in the z direction of the current UCS.
Path	Specifies the extrusion height and angle by another entity. Pick an open entity, such as a line, arc, spline, or polyline. The path entity cannot lie in the same plane as the extrusion entity.

Specify angle of taper for extrusion	Specifies the taper angle for the extrusion: Enter a number - specifies the angle; enter a negative number to taper outwards. Pick a point - specifies the angle; you are prompted: Second point - pick another point in the drawing. The angle must be shallow enough not to cut off that the top of the extrusion. (This prompt does not appear with the Path option.)

Grips Editing

Extrusion can be edited directly through grips:

Select the extruded solid. Notice that it has two grips.
Drag a grip to move the extrusion. (Both grips perform the same functions: move.)
