To create a Circle – Radius surface do the following:

1. Select Axial Curve. It can be a path, a route, an open profile, an edge or a sequence of smoothly-joint edges.

2. Select Support Curve if necessary. It can be a path, a route, an open profile, an edge or a sequence of smoothly-joint edges. In case the support curve is not selected, the axial curve sets the orientation for generating profiles.

3. Select Radius Curve if necessary. It can be a path, a route, an open profile, an edge or a sequence of smoothly-joint edges.

4. Set Radius in case radius curve is not set. The value can be constant or variable, set by the diagram. The abscissa axis of the diagram is the supporting curve length.

5. Change or leave the default values for the parameters determining design accuracy.

6. Confirm the surface creation.
