CurveCollection Class

class NXOpen.CurveCollection

Bases: object

Represents a collection of NXOpen.Curve.

Iterating this collection only returns live uncondemned objects contained in the owning part of the collection. Note that NXOpen.Curve is a smart object and many smart objects are condemned as they only exist to support other objects and are not displayed. To obtain an instance of this class, refer to NXOpen.BasePart

Method Detail

CreateArc

CurveCollection.CreateArc

Overloaded method CreateArc

  • CreateArc(startPoint, pointOn, endPoint, alternateSolution)
  • CreateArc(startPoint, pointOn, endPoint, alternateSolution)
  • CreateArc(center, matrix, radius, startAngle, endAngle)
  • CreateArc(center, xDirection, yDirection, radius, startAngle, endAngle)

-------------------------------------

Creates an NXOpen.Arc that passes through the three specified points.

Signature CreateArc(startPoint, pointOn, endPoint, alternateSolution)

Parameters:
  • startPoint (NXOpen.Point3d) – Start point
  • pointOn (NXOpen.Point3d) – Point that the arc passes through.
  • endPoint (NXOpen.Point3d) – End point
  • alternateSolution (bool) – If true, the arc will be created using the alternate solution instead of the regular solution. The alternate solution for an arc is the portion of the full circle that is left out of the regular solution. For example, if the regular solution is an arc that goes from 0 to 45 degrees, the alternate solution will be an arc with the same center and origin but that goes from 45 degrees to 360.
Returns:

a tuple
Return type:

A tuple consisting of (arc, startAndEndGotFlipped). arc is a NXOpen.Arc. startAndEndGotFlipped is a bool. If true, the start point of the arc that is created is at the end point parameter to this method and the end point of the arc is at the start point parameter. In other words, suppose you execute arc = Curves.CreateArc(startPointParam, pointOnParam, endPointParam, false, flipped). If flipped is true, then arc.StartPoint equals endPointParam and arc.EndPoint equals startPointParam.
