To create a Circle – Tangent to Surface surface do the following:

1.Select Tangent Face. It can be set by a face, a surface or a sequence of smoothly-joint faces.

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

3.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.

4.Set Angle. The range for angle value is from 0° to 180°. The value can be constant or variable, set by the diagram. In case you use the diagram, the range is from 0 to 179,99°. The diagram cannot switch from the negative to the positive area or vice versa. The abscissa axis of the diagram is the supporting curve length. The angle is settled symmetrically in both sides from the tangent point.

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

6.Confirm the surface creation.
