Inner Radius
If you set Type to Ring, this denes the inner radius of the ring.
Start Angle, End Angle
Using these two values you can dene the start and end point of the arc element. 0° denes the value
as the positive X-axis, 90° the positive Y-axis, 180° the negative X-axis, etc. These examples assume
you are working in the XY plane, as mentioned earlier.
Plane
With this drop-down list you choose in which of the three planes the spline primitive is created.
Reverse
Enabling this option will reverse the point order of the spline.
Intermediate Points, Number, Angle
These interpolation settings dene how the intermediate points of the spline are produced. For more
information on these settings, look up ‘interpolation, spline’ in the index.
Circle
This command creates circles, rings, ellipses and ellipse rings. It is also suitable for the creation of
hoses or tubes using NURBS objects.
