Is there any tool for writing Dicom-RT structure easily?

[hwkim0325]

Hello, I've been recently using Evil-DICOM library.
And I'm trying to make a RT Dicom using contour data which consists of several polygonal data with points
However, I noticed that there are many tags about rt contours, and it requires that write several sequence data.

{(3006,0010) : ReferencedFrameOfReferenceSequence, Sequence : 1 Items} EvilDICOM.Core.Interfaces.IDICOMElement {EvilDICOM.Core.Element.Sequence}
{(3006,0020) : StructureSetROISequence, Sequence : 16 Items} EvilDICOM.Core.Interfaces.IDICOMElement {EvilDICOM.Core.Element.Sequence}
{(3006,0039) : ROIContourSequence, Sequence : 16 Items} EvilDICOM.Core.Interfaces.IDICOMElement {EvilDICOM.Core.Element.Sequence}
{(3006,0080) : RTROIObservationsSequence, Sequence : 16 Items}

I think there is a sophisticated tool for writing RT structure with a simple function in Evil-DICOM.
Is there any?
