Edge.AsCurveFollowingFace

Description:
Returns a curve that corresponds to this edge as oriented in its topological direction on the specified face.

Remarks:
Evaluating the edge using EvaluateOnFace gives the same result as evaluating the curve returned by AsCurveFollowingFace with a normalized curve parameter. When a Hermite spline is returned, the two evaluated points will be approximately equal.

faceForDir

Specifies the face, on which the curve will follow the topological direction of the edge.

Return Value Curve It can be an Arc, Line, or HermiteSpline.
