Currently there has been much interested in developing the watermarking for 3D graphic data of mesh model or NURBS. However, the watermarking technique based on 3D CAD drawing leaves something to be desired. This paper proposes a watermarking technique for 3D design drawing using the components of Line, 3DFACE and ARC based on vertex that prevent the infringement of copyright from unlawfulness reproductions and distribution. By experimental result, we confirmed the invisibility of embedded watermarks as well as the robustness in geometrical attacks and file conversion to DWG, DXF, DWT and DWS.
