There is an old unanswered thread:
The Documentation about
Verifies an object is an arc curve object or is a NURBS curve object that looks like an arc.
can somebody post a Nurbs curve that looks like an arc - and IsArc returns true ?
If I _rebuild an arc and set the tolerance - parameter of IsArc (much) higher then the deviation - IsArc still returns false.
If I build a degree 2 curve and set the weight according to an similar Arc - isArc still returns false.
The function behaves like a IsRealArc Function - the behaviour i would need.
But the documentation claims, the Function is a “IsShapelikeArc” - the behaviour that would trouble me, but also would be necessary in other cases.
thanks for clarifying this. - best Tom
