Namespace: Autodesk.Revit.DB Class: Curve

Curve.GetEndParameter

Method

Description:
Returns the raw parameter value at the start or end of this curve.

Remarks:
The start and end value of the parameter can be any value (as it is determined by the system based on the inputs). For curves with regular curvature like lines and arcs, the raw parameter can be used to measure along the curve in Revit's default units (feet). Raw parameters are also the only way to evaluate points along unbound curves.
