Extrudes polygonal faces and edges.

Parameters

See also: Extrude

Using PolyExtrude

Select the face or edge you want to extrude.
Click the PolyExtrude tool on the Polygon tab.
Transform the faces or edges using either the transform manipulator handles in the scene view or editing the values in the parameter editor.

Continue extruding another face or edge	Select the face or edge you want to extrude. Press Q .
Scale with inset	Change the Inset value on the Local tab of the parameter editor from 0 to desired value.
Close an object	Turn on desired checkboxes on the Options tab of the parameter editor.
Extrude multiple faces or edges	Select multiple faces or edges. Choose either No, Use Normals, or Average Positions on the Keep Points Shared drop-down menu on the operation controls toolbar. Extrude the same way as described above.
Turn off local control	Click the handles and turn off the Local Control checkbox.

Local variables

PR	Primitive number. For example you can use `fit01(rand($PR), 0.2, 0.6)` in the Translate Z field to create random extrusion heights for each input polygon face.

Parameters

Group

Geometry to extrude.

Local

Transformation Order

Order in which to apply local transformation.

Rotation Order

Order in which to apply local rotations.

Translation

Local xyz translation.

Rotate

Local xyz rotation.

Scale

Local xyz scale.

Inset

Amount by which to inset the face, on edges this parameter is treated as an addition to x scale.

Symmetry Axis

Sets the local axis of the first face that is used to mirror the extrusion.

Keep Points Shared

No	Extrudes shared points individually.
Use Normals	Extrudes shared points together. Uses the face normals to determine the location of the point extrusion.
Average Positions	Extrudes shared points together. Places the extrusion at the average location of the points had they been extruded separately.

Global

Transformation Order	Order in which to apply global transformation.
Rotation Order	Order in which to apply global rotations.
Translation	Global xyz translation.
Rotate	Global xyz rotation.
Scale	Global xyz scale.
Shear	Global shearing. The three values represent shearing in the X direction on the XY plane, in the X direction on the XZ plane, and in the Y direction on the YZ plane, respectively.

Options

Divisions

Number of divisions along the side of extrusion./divs

Output Front

Toggle whether or not to output a front face, ignored for edges.

Output Back

Toggle whether or not to output a back face, ignored for edges.

Output Side

Toggle whether or not to output side faces.

Remove Zero Area Sides

When on, sides that are degenerate are removed. Such sides can result from an extrusion that scales but does not translate.

Remove Shared Sides

When on, extruded sides that lie one on another are removed. Such sides can result from global extrusion of adjacent faces.

Orient Edge Extrusions

When on, faces extruded from edges are oriented to match neighboring faces.

Consolidate Points

None	No points are consolidated.
Per-Face	Points created by each face are consolidated.
All	All new points are consolidated.
All Per-Point	The extruded points maintain their consolidation (that is to say, they are consolidated if they were consolidated, and remain unique if they were unique.) This option is preferable to “All” since consolidation doesn’t require extra computation. When “Keep Points Shared” is not used, this option behaves exactly as “All”.

Tolerance

Tolerance used when consolidating points and determining which are shared faces.

Group

Output Groups	When on, primitives groups are exported.
Front Group	Name of group in which to place front faces.
Back Group	Name of group in which to place back faces.
Side Group	Name of group in which to place side faces.
