At present in order to access old Files I am running CorelDraw on the Mac, this has the ability to produce a .DXF File that imports into S3D. This is my favourite solution.
There are many On-Line, including free of charge, offering this service, I cannot recommend because I have never used any.
In a previous Thread:

I mentioned need for awareness regarding handing Imported Text via this method.
