revit 创建sketchplane

sketchplane在创建某些图元时候可以用到

public void CreateSketchPlaneByPlane()
{
   Document doc = this.ActiveUIDocument.Document;    
   using(Transaction trans = new Transaction(doc, "Create model arc."))
   {
     trans.Start();    
     Plane plane = this.Application.Create.NewPlane(XYZ.BasisZ, XYZ.Zero);
     SketchPlane sketchPlane = SketchPlane.Create(doc, plane);
            
     Arc arc = Arc.Create(plane, 5, 0, Math.PI * 2);
     ModelCurve modelCircle = doc.FamilyCreate.NewModelCurve(arc, sketchPlane);
     trans.Commit();
   }
}
