how to create dimension on circular curve?

[Anonymous]

Hi.

I am trying to create dimension on circular curve like this.

I've tried,

ReferenceArray refArray = new ReferenceArray();
refArray.Append(circularCurve.GetEndPointReference(0));
refArray.Append(circularCurve.GetEndPointReference(1));

var point1 = new XYZ(startX, startY, 0);
var point2 = new XYZ(startX + diameter, startY, 0);

var line = Line.CreateBound(point1, point2);

doc.Create.NewDimension(view, line, refArray, dimensionType);

but circularCurve two end point are the same.

so it is created in this way.

and I've already tried this way. (create dummy curve, then create dimension and delete dummy curve.)
