## Options

### Offset

Parameter ID: `MDATA_EXTRUDE_OFFSET` · Range: [-∞..+∞m]

Defines the length of the extrusion.

### Offset Variation

Parameter ID: `MDATA_EXTRUDE_VARIANCE` · Range: [0..+∞%]

Varies the length of the extrusion. This option is not available if Preserve Groups is enabled. The value you enter is subtracted from 100% to give the start of the variation range.

0% - No deviation from the selected offset value.

60% - All selected polygons are extruded between 40% and 100% of the Offset value.

100% - All selected polygons are extruded between 0% and 100% of the Offset value.

180% - All selected polygons are extruded between -80% and 100% of the Offset value.

Offset Variation 0% and 60%.

### Subdivision

Parameter ID: `MDATA_EXTRUDE_SUBDIVISION` · Range: [0.00..+∞]

![Image: 003676.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/003676.jpg)\
Subdivision set to 0 (left) and 3 (right).

Defines the number of subdivisions along the extrusion.

### Create N-gons

Parameter ID: `MDATA_EXTRUDE_CREATENGONS`

If this option is enabled, n-gons will be created along the length of the extrusion. Although you will not see edges along the length of the extrusion, the Subdivision setting is still applied internally.

# Extruding Polygons

### Create Caps

Parameter ID: `MDATA_EXTRUDE_CREATECAPS`

Enable this option to create a cap at the base of the extrusion. This gives you a quick way to create a closed volume.

### Preserve Groups

Parameter ID: `MDATA_EXTRUDE_PRESERVEGROUPS`

If this option is enabled, the connected polygons will stay together during the extrusion, assuming they do not exceed the Maximum Angle relative to one another.

Preserve Groups enabled and disabled.

### Maximum Angle

Parameter ID: `MDATA_EXTRUDE_ANGLE` · Range: [0..180°]

If **Preserve Groups** is enabled, polygons not exceeding this angle to each other are kept together. Polygons exceeding this angle are broken apart during extrusion.

# Extruding edges

To extrude the edges interactively, drag the mouse (this changes the Offset value, i.e., the length of the extrusion).

![Image: 003677.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/003677.jpg)

With the mouse button still held down, you can `Shift`+drag to change the direction of the extrusion. If, at this point, you still keep the mouse button held down and release the `Shift` key and drag, you will change the **Offset** once more. So, by holding down or releasing the `Shift` key while you drag, you can change between adjusting the extrusion length and the extrusion direction.

### Rotation

Parameter ID: `MDATA_EXTRUDE_EDGEANGLE` · Range: [-∞..+∞°]

Here you can set the angle of the edge extrusion. You can also change the extrusion angle interactively in the viewport by holding down `Shift` during the extrusion.

### Quantize Rotation

Parameter ID: `MDATA_EXTRUDE_EDGESNAP`

### Angle

Parameter ID: `MDATA_EXTRUDE_EDGESNAPVALUE` · Range: [0..180°]

If **Edge Snap** is enabled, the extrusion angle will be constrained to the **Angle** setting. For example, to constrain the extrusion angle to steps of 45 degrees, enable the option and set Angle to 45°.

# Extruding Points

### Bevel

Parameter ID: `MDATA_EXTRUDE_BEVEL` · Range: [-∞..+∞m]

### Bevel Variation

Parameter ID: `MDATA_EXTRUDE_BEVEL_VARIANCE` · Range: [0..+∞%]

![Image: 003678.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/003678.jpg)\
Before extrusion (left), after extrusion without the `Shift` key (center) and the base of the extrusion beveled with the Shift key held down and a value greater than 0 (right).

When extruding in point mode, the points will be extruded in the direction of the point Normals. The original points at the base of the extrusion will be beveled with a value of 0 initially. You can adjust the **Bevel** parameter interactively during the extrusion by holding down `Shift` while you drag.
