回复: Dear Robin,do you think that isClosed value should be Zero for a partial circle?
R:
Yogy,
The parametric range is the valid range for the curve. If the curve is infinite (such as a line), then the parametric maximum is the largest permissible value in the parametric space.
Use Edge::GetCurveParams2 to determine if a circular edge is a complete circle or an arc.
Also, you may need to create a TrimmedCurve before getting the parameters.
