Compute a freeform surface that blends between two surface rails. Each rail may consist of one or more surface curves on one or more surfaces. The tangent direction the blended surface leaves each rail is determined by flipLeft and flipRight.

Long name (short name)TypeDefaultFlags
leftCurve (lc) nurbsCurveNULLarrayoutputinputconnectable
The surface curves comprising the left boundary.
rightCurve (rc) nurbsCurveNULLarrayoutputinputconnectable
The surface curves comprising the right boundary.
leftRail (lr) nurbsCurveNULLoutputinputconnectable
The left rail boundary.
rightRail (rr) nurbsCurveNULLoutputinputconnectable
The right rail boundary.
multipleKnots (mk) booltrueoutputinputconnectablestorable
If true, use the new blend which produces fully multiple interior knots
positionTolerance (pt) double0.1outputinputconnectablestorablekeyable
The positional C(0) tolerance of the blend surface to the adjacent surfaces.
tangentTolerance (tt) double0.1outputinputconnectablestorablekeyable
The tangent G(1) continuity tolerance of the blend surface to the adjacent surfaces.
autoNormal (an) booltrueoutputinputconnectablestorablekeyable
If true, the direction of each starting tangent is computed based on given geometry.
flipLeftNormal (fln) boolfalseoutputinputconnectablestorablekeyable
If true, flip the starting tangent off the left boundary.
flipRightNormal (frn) boolfalseoutputinputconnectablestorablekeyable
If true, flip the starting tangent off the right boundary.
autoAnchor (aa) booltrueoutputinputconnectablestorablekeyable
If true and both paths are closed, automatically determine the value on the right rail so that they match
leftAnchor (la) double0.0outputinputconnectablestorablekeyable
The reference parameter on the left boundary where the blend surface starts in the case of the closed rail.
leftStart (ls) double0.0outputinputconnectablestorablekeyable
The reference parameter on the left boundary where the blend surface starts.
leftEnd (le) double1.0outputinputconnectablestorablekeyable
The reference parameter on the left boundary where the blend surface ends.
reverseLeft (rvl) boolfalseoutputinputconnectablestorablekeyable
If true, reverse the direction off the left boundary. autoDirection must be false for this value to be considered.
rightAnchor (ra) double0.0outputinputconnectablestorablekeyable
The reference parameter on the right boundary where the blend surface starts in the case of the closed rail.

reverseRight (rvr) boolfalseoutputinputconnectablestorablekeyable
If true, reverse the direction of the right boundary. autoDirection must be false for this value to be considered.
outputSurface (os) nurbsSurfaceNULLoutputconnectable
The computed blend surface.
