Hi Danny,

>>CoCreate Modeling Personal Edition (PE) is worth a try from PTC makers of Pro-E, they say the PE is free but I don't know if they mean, 'for free' or free download

It is Free, but requires activation (on each execution), so a need for the software to connect out to their servers each time it is run (it does allow 72 hrs "off-line" use)

You can import various formats, but the export is restricted, there is STL output~ But, that is limited to 1086 triangles, so not anything that can be worked with.
