## Object Properties

### Radius

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

The n-Side is inscribed in a so-called **perimeter**. This determines the radius of this perimeter.

### Sides

Parameter ID: `PRIM_NSIDE_SIDES` · Range: [2..2147483647]

Use the value to determine how many regular line segments the n-Side should be made up of.

Various n-Sides with 3, 6, 10 and 20 Sides

You can also use the value **2**. A line is then created.

### Rounding

Parameter ID: `PRIM_NSIDE_ROUNDING`

### Radius

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

If you activate this option, all corners are rounded with the value specified under **Radius**. (Instead of an n-Side there is now an **n-Round**)

### Plane

Parameter ID: `PRIM_PLANE`

Here you can define the layer on which the spline should come to rest.

### Reverse

Parameter ID: `PRIM_REVERSE`

Enabling this option will reverse the point order of the spline (see also [Spline Primitives](https://help.maxon.net/c4d/en-us/Content/html/5420.html.md).

### Interpolation

Parameter ID: `SPLINEOBJECT_INTERPOLATION`

### Points

Parameter ID: `SPLINEOBJECT_SUB` · Range: [0..5000]

### Angle

Parameter ID: `SPLINEOBJECT_ANGLE` · Range: [0..90°]

Here you set how the spline is to be subdivided during further processing. This is always important when you generate meshes with the help of generators. Depending on which type you select from the menu for **Interpolation**, you have further options.

Off

![Image: 001610.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/001610.jpg)

This type of interpolation uses the interpolation points of the spline directly and connects them via straight lines without setting additional intermediate points.

You cannot make entries in the fields for **Points** or **Angle**.

Natural

![Image: 001611.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/001611.jpg)

This type of interpolation divides the spline in such a way that a corresponding number of **Points** are used per interpolation point. The inserted points follow the natural course of the spline directly, i.e. they are closer together at support points than in between. The curve resulting from this interpolation does not necessarily pass through the interpolation points. If a spline has several segments, the value for **Points** applies to each interpolation point of each segment.

You cannot make any entries in the **Angle** field.

Uniform

![Image: 001612.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/001612.jpg)

This interpolation type divides the spline so that the selected number of **Points** is used for each interpolation point. The points are exactly the same distance apart. The curve resulting from this interpolation does not necessarily pass through the interpolation points. If a spline has several segments, the value for **Points** applies to each interpolation point of each segment.

You cannot make any entries in the **Angle** field.

NoteFor the two Interpolation types **Natural** and **Uniform**, the new number of points is calculated as follows:\
Opened spline: ((Points + 1) \* (number_of_base_points - 1)) +1\
Closed spline: (Points + 1) \* number_of_base_points\
This means, for example, that an open spline with four support points and a Points value of 2 is divided into a total of ((2+1)\*(4-1))+1 = 10 points. If you close this spline, (2+1)\*4 = 12 points are used. This procedure prevents, for example, a spline from being split more roughly after it has been closed.

Adaptive

![Image: 001613.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/001613.jpg)

This type of interpolation always sets intermediate points if the angular deviation of the curve is greater than the value entered under **Angle**. The curve resulting from this interpolation passes exactly through the interpolation points. If a spline has several segments, the value for **Angle** applies to each segment.

In contrast to the other interpolation types, different interpolations result if you change the interpolation point sequence of the spline.

The subdivision, also known as **Adaptive**, produces the best results in rendering. This is therefore the default Interpolation method.

You cannot make any entries in the **Points** field.

Subdivided

**Subdivided** is similar to the **Adaptive** type. In addition, intermediate points are inserted until the segments in between are shorter than the length defined under **Max Length**. This does not necessarily mean that the point distances correspond exactly to Max Length. Smaller values lead to higher quality, but as is so often the case, they also have the disadvantages associated with high point counts (slower redraw speed in the editor, etc.).

This enables significantly better rendering quality, especially with deformed text. If you enter the same value for **Max Length** as for **Size** in the *Extrude* object (**Caps** tab, **Regular Grid** option activated), you will get fairly perfect cap areas and edges without shading errors, as the subdivisions of letters and their caps fit together and triangles do not have to be inserted **arbitrarily** to connect the two mesh elements.

### Max Length

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

This parameter, which is only effective in **Subdivided** Interpolation mode, controls the maximum spline segment length without an intermediate point (see above for **Subdivided**) must be inserted.
