[Lab] [lab] STL conversion. Going backwards

[Laxman Pradhan]

If you want to make a very good base mesh, you need to do something called
retopology. As you probably discovered, there are some software packages
that do this automatically, but they will never be as good as manually doing
it. If you want to do it for free, I would suggest blender:

Its free and has good retopo tools. This will of course take a long time to
do, especially if you have to learn the software from scratch. I don't know
of any automated tools that are free, so I can't help you there.
