coincidentConstraint Does Not Work,

Hi, 

    the following C++ Code to Test addCoincident(point, entity) Does Not Work.

I will appreciate if someone can make it work.

What is the outcome of this script and what is the outcome you are expecting?  I think I may know the issue, but want to make sure I understand your problem first.

Hi Patrick,

    I was expecting Circle3D to move from sketchPoint2((8, 5, 0) to sketchPoint(0,0,0).

Thanks,

OK, yah thats what I thought you were going for. 

In your code you are creating: 

sketchPoint2, sketchPoint

These are now just generic new points in the sketch, they are not associated or fixed to the positions where you created them.  So effectively what you have done is create two new points and made them coincident. Which doesn't really do much.  

What you want to do, and I apologize for any syntax errors, C++ is not my expertise.  But basically you want to create a constraint between the actual center "Sketch Point" of the circle and the fixed origin of the sketch.

Ptr<CoincidentConstraint> coincidentConstraint = constraints->addCoincident(circle3D->centerSketchPoint, sketch->originPoint);

Hi Painsberry,

The following as you suggested Worked Okay. 

Thanks.

 // Use the returned lines to add some constraints.
 Ptr<GeometricConstraints> constraints = sketch->geometricConstraints();
 if(!constraints)
  return false;

 Ptr<SketchCircle> circle5 = sketchCircles->addByCenterRadius(Point3D::create(8, 5, 0), 5);
 if (!circle5)
  return false;

 Ptr<CoincidentConstraint> coincidentConstraint = constraints->addCoincident(circle5->centerSketchPoint(), sketch->originPoint());
 if(!coincidentConstraint)
  return false;
