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/subentities to extrude or set [MOde]: (Choose one or more closed 2D entities or faces of 3D solids.)

Entities in set: 1

Select entities/subentities to extrude or set [MOde]: (Choose more entities, or press Enter to continue.)

Specify height of extrusion or [Direction/Path/Taper angle] <xx.xx>: (Enter a number, or pick two points, or press Enter to accept the default height, or choose an option.)

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, regions or faces of 3D solids. The resulting entity is either a 3D solid or a surface, depending on the current value of the Mode option: Depending on the value of the DELOBJ system variable the source entities or either retained or deleted or you are prompted whether the entities are to be deleted or not..
Mode	Sets the entity type of the extrusion: solid or surface Prompts you: Choose type of created entity [SOlid/SUrface] <SOlid> - choose solid or surface or press Enter to accept the current mode.
Specify height of extrusion	Specifies the height of the extrusion. The extrusion height is measured perpendicularly to the selected entity. Use the Direction option to set the extrusion direction differently. Enter a number - specifies the height; enter a negative number to extrude downwards. Pick two points - the distance between two points specifies the height.
Direction	Sets the extrusion direction and height. Prompts you: Specify start point of direction - pick a point. Specify end point of direction - pick a point.
Path	Specifies the extrusion height and angle by another entity. Prompts you: Select extrusion path or [Taper angle] - 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.
Taper Angle	Specifies the taper angle for the extrusion. Prompts you: Specify angle of taper for extrusion <0>: Enter a number - specifies the angle; enter a negative number to taper outwards. Define the angle by picking two points. The angle must be shallow enough not to cut off that the top of the extrusion.

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.)
