scdoc to obj conversion is typically searched by users that have 3D file (.scdoc) from SpaceClaim software and want to export it to 3D OBJ format, typically so they can work with it in another software.
Unfortunately everything points to the fact that .scdoc files are only supported in the original software and this is also the tool that can export these files to another format. Which means that without access to SpaceClaim it is pretty much impossible to achieve this export.
