Several CAD programs can take a 3D part (model) like the one created using SolidWorks (.sldprt) and export it as 2D technical drawing in a DXF format. Many 3D modeling tools nowadays support SolidWorks formats, so you should have no trouble in finding one suitable for your needs. You can also achieve sldprt to dxf conversion with some special conversion software.
