## Inlay

The Cogwheel spline does not necessarily consist of only one segment. Various types of cutouts can also be made. Many of the following settings can be modified without restriction, which can easily result in unwanted overlapping. Therefore, you should be careful when making modifications because the Extrude object, for example, can end up producing irregular caps surfaces.

### Orientation

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

This setting is available for all cogwheel types and can be used to rotate the Inlay independent from the rest of the cogwheel (e.g., the teeth).

### Invert

Parameter ID: `PRIM_COGWHEEL_INLAY_INVERT`

**Invert** is currently only available for the Arches **Type**. Enable this option if you want to orient circular or elliptical elements outwardly and not towards the cogwheel's center point.

### Type

Parameter ID: `PRIM_COGWHEEL_INLAY_TYPE`

![Image: 038025.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/038025.jpg)\
From left to right: **Type** None, Spokes, Holes, Arches, Waves.

Select the type of cogwheel from this menu. The corresponding options will be displayed:

**None**: No inlay, the cogwheel will be solid.

**Spokes**: Spokes whose edges can be beveled (Bevel) will be added.

**Holes**: Creates bold holes / holes in a radial arrangement.

**Arches**: Creates radially arranged holes or ellipses.

**Waves**: Sinus-shaped spokes can be created.

# Spokes

The most important settings for each type of cogwheel.

### Spokes

The **Spokes** setting defines the total number of spokes.

### Outer Radius

Parameter ID: `PRIM_COGWHEEL_SPOKES_OUTER_RADIUS` · Range: [0..+∞m]

### Inner Radius

Parameter ID: `PRIM_COGWHEEL_SPOKES_INNER_RADIUS` · Range: [0..+∞m]

These values define the outer and inner spoke radii. These values can also be modified interactively in the Viewport using the handles.

### Outer Width

Parameter ID: `PRIM_COGWHEEL_SPOKES_OUTER_WIDTH` · Range: [0..100%]

### Inner Width

Parameter ID: `PRIM_COGWHEEL_SPOKES_INNER_WIDTH` · Range: [0..100%]

These values define the outer and inner spoke width as a percentage of the space available for each spoke.

### Bevel

Parameter ID: `PRIM_COGWHEEL_SPOKES_BEVEL` · Range: [0..100%]

If this value is set to 0, the spokes will have sharp edges. If the **Bevel** value is increased, the edges will be rounded correspondingly.

# Holes

### Holes

Parameter ID: `PRIM_COGWHEEL_HOLES_COUNT` · Range: [1..2147483647]

The **Holes** setting defines the total number of holes that will be arranged radially on the cogwheel.

### Radius

Parameter ID: `PRIM_COGWHEEL_HOLES_RADIUS` · Range: [0..+∞m]

This value defines the radius of the holes. This value can also be modified interactively in the Viewport using the handles.

### Ring Radius

Parameter ID: `PRIM_COGWHEEL_HOLES_DISTANCE` · Range: [0..+∞m]

This value defines the radius of the radial arrangement of the holes. This value can also be modified interactively in the Viewport using the handles.

### Arc

Parameter ID: `PRIM_COGWHEEL_HOLES_ARC` · Range: [0..359°]

This value can be used to transform the circular holes to arched ellipse-shaped holes. The angle entered here defines the distance between both ends of the elliptical shape.

# Arches

### Arches

Parameter ID: `PRIM_COGWHEEL_ARCHES_COUNT` · Range: [1..2147483647]

The **Arches** setting defines the number of radially arranged arched cutouts on the cogwheel.

### Outer Radius

Parameter ID: `PRIM_COGWHEEL_ARCHES_OUTER_RADIUS` · Range: [0..+∞m]

### Inner Radius

Parameter ID: `PRIM_COGWHEEL_ARCHES_INNER_RADIUS` · Range: [0..+∞m]

These values define the outer and inner radii of the spokes. These values can also be modified interactively in the Viewport using the handles.

### Arc Fraction

Parameter ID: `PRIM_COGWHEEL_ARCHES_ARC_FRACTION` · Range: [0..100%]

This setting defines the size of the arched cutouts and therewith the spoke width.

### Stretch

Parameter ID: `PRIM_COGWHEEL_ARCHES_STRETCH` · Range: [0..100%]

The higher the **Stretch** value, the more the cutouts will stretch in the direction of the cogwheel's center point, and the narrower the spokes will be.

# Waves

### Waves

Parameter ID: `PRIM_COGWHEEL_WAVES_COUNT` · Range: [1..2147483647]

The **Waves** setting defines the number of sinus-shaped spokes.

### Outer Radius

Parameter ID: `PRIM_COGWHEEL_WAVES_OUTER_RADIUS` · Range: [0..+∞m]

### Inner Radius

Parameter ID: `PRIM_COGWHEEL_WAVES_INNER_RADIUS` · Range: [0..+∞m]

These values define the outer and inner spoke radii between which the sinus-shaped spokes lie. These values can also be modified interactively in the Viewport using the handles.

### Frequency

Parameter ID: `PRIM_COGWHEEL_WAVES_FREQUENCY` · Range: [0..+∞°]

This value defines the number of oscillations per spoke. For example, a value of 0° will create no oscillation and a value of 360° will produce maximum oscillation. Very high values will create almost psychedelic effects …

### Amplitude

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

This value defines the degree of sinus oscillation. The higher the value, the more the spoke will be deformed.

### Phase

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

This value defines the sinus oscillation's offset, i.e., you can define when the oscillation should start, e.g., at the wave's trough or at null. This setting can be used for fine-tuning.

### Width

Parameter ID: `PRIM_COGWHEEL_WAVES_WIDTH` · Range: [0..100%]

This value defines the spoke width between 0 until it comes in contact with the neighboring spoke.

# Center Hole option and settings

This value defines the radius of the hole. This value can also be modified interactively in the Viewport using the handles.

### Cutout

Parameter ID: `PRIM_COGWHEEL_CUTOUT`

### Width

Parameter ID: `PRIM_COGWHEEL_CUTOUT_WIDTH` · Range: [0..+∞m]

### Cutout Orientation

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

This value defines the angle of the milling groove (independent of the rest of the cogwheel).
