dft to jt conversion is probably related to export of Solid Edge drawings (.dft) to JT Open CAD 3D model (.jt), something that is certainly doable. The best software for this of course would be Solid Edge, but it's quite often people that do not have access to it that need to export the files. We do not know about any 3rd party solution, so perhaps reach out to some Solid Edge online community and ask for quick export for your files.
