RFCurveTools.OffsetNurbsCurveOnShell3 (Available After rapidform2006)

Description

Creates a offset curve of a specified NURBS curve and returns the RFErrorCode value indicating whether an error occurs.

Syntax

Function RFCurveTools.OffsetNurbsCurveOnShell3(curveID As RFEntityID, distance As Double, isLeft As Boolean, iNumSteps As Long, pOffsetCurveID As RFEntityID) As RFErrorCode

The OffsetNurbsCurveOnShell3 syntax has these parts:

Part	Description
curveID	[IN] RFEntityID Required. NURBS curve's entity ID to offset.
distance	[IN] Double Required. Offset distance.
isLeft	[IN] Boolean Required. Flag indicating if a newly offseted curve is created on the left-hand side or not.
iNumSteps	[IN] Long Required. Number of steps to reach to specified distance.
pOffsetCurveID	[OUT] RFEntityID Required. NURBS curve's entity ID which is newly offseted.

Remarks

The NURBS curve, specified by curveID, should have a connected shell on which the offset will be performed.
This method is faster than OffsetNurbsCurveOnShell and OffsetNurbsCurveOnShell2 with bigger distance.
The greater number of iNumSteps produces the more precise results, but elapsed time will be increased linearly.
