We use the following code to evaluate an edge:
const ON_BrepEdge * prnEdge = …;
ON_Interval rnCurveInterval = prnEdge->Domain();
const ON_Curve* prnCurve = ON_Curve::Cast(prnEdge)
// for a dT within rnCurveInterval
prnCurve->Evaluate(dT, 1, 3, rgdPosition);
There is a bug with the code as the edge domain may not be the same as the curve domain. Could Rhino make some correction to the code?
