Q:
Subject: Dear Robin,do you think that isClosed value should be Zero for a partial circle?

Dear Robin,

When I try to get the following parameters (shown in red font, such as m_min_t, m_max_t, isClosed, isPeriodic) from partial curve in Sketch, I get the incorrect result for the parameters. For example, for a partial circle, I get the incorrect result of the parameters as follows.

m_min_t = 0;

m_max_t = 6.28;

isClosed = 1;

isLPeriodic = 1;

I think that isClosed value should be Zero for a partial circle. Do you?

The source file is attached in the Email.

My code is as follows.

ISketchSegment swSketchSegment(dSketchSegment);

  dSegmentCurve = swSketchSegment.GetCurve();

  if (dSegmentCurve != NULL)

  {

    int isPeriodic, isClosed;

    ICurve swCurve(dSegmentCurve);

    swCurve.GetEndParams (&m_min_t, &m_max_t, &isClosed, &isPeriodic);

swCurve.DetachDispatch();

}

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.
