## Caps

### Caps

Parameter ID: `PRIM_CYLINDER_CAPS`

Enable this option to add caps to the top and base of the cylinder. Otherwise, the cylinder is hollow.

Caps enabled (left) and disabled (right).

### Segments

Parameter ID: `PRIM_CYLINDER_CSUB` · Range: [1..1000]

Defines the number of subdivisions of the caps in a radial direction. The subdivision along a cap's circumference is defined by Rotation Segments.

### Fillet

Parameter ID: `PRIM_CYLINDER_FILLET`

Assuming that the cylinder has caps you can use this option to apply a fillet or chamfer to the join between the cylinder body and the caps.

### Radius

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

Enter the radius of the fillet.

### Segments

Parameter ID: `PRIM_CYLINDER_FSUB` · Range: [1..1000]

With Fillet selected you can choose the degree of the roundness with this option. The higher the value the smoother the join will appear; enter a value of 1 to achieve a chamfer. In the picture is a rounded cylinder. To the left is a chamfer, then a rough fillet and, on the right, a high-value, smooth fillet.

From left to right: Fillet Segments set to 1 (a chamfer), 3 and 10.

The roundness can be set as high as the cylinder's radius — the caps will then be hemispherical.
