AutoCAD .NET :: How To Change Dimensional Constraint From Annotational To Dynamic

public class DimConstraints{ [CommandMethod("Test")] public void Test() {
Database db = HostApplicationServices.WorkingDatabase;
using (Transaction trans = db.TransactionManager.StartTransaction()){
Circle circle = new Circle { Center = Point3d.Origin, Radius = 10 };
ObjectId modelId = SymbolUtilityServices.GetBlockModelSpaceId(db);
BlockTableRecord model = (BlockTableRecord)modelId.GetObject(OpenMode.ForWrite); model.AppendEntity(circle);
trans.AddNewlyCreatedDBObject(circle, true);
AssocUtil.CreateRadialDimConstraint(circle.ObjectId, circle.StartPoint, circle.StartPoint);
trans.Commit(); } }}

The above codes use the simplified .NET API for accessing AutoCAD parameters and constraints from: [URL] ....

The above codes can create a radial dimensional constraint. But the type of the dimensional constraint is annotational. How to change it to a dynamic constraint?
