Endpoints for Curve Connections

The following rules apply to endpoint selection when you create connections between two curves or connections between a curve and a surface.

Connections between Two Curves

To create a Tangent connection between curves, the endpoint of the follower must be a soft point on the leader.

Connections between a Curve and a Surface

Connection	Endpoint Rule
G1 - Surface Tangent G2 - Surface Curvature G3 - Surface Acceleration	Must be a soft point to a surface, a surface boundary, or a COS
Draft Tangent with a planar reference	Must be a soft point to any other curve
Draft Tangent with a surface reference	Must be a soft point on the surface boundary or a COS
