Has anyone used Cad Exchanger?

Its a bit spendy, $650 for a one user perpetual license, but I was considering it. As a home hobbyist/model designer, I get a lot of STL and OBJ files that aren't easily converted for use in MOI or Alibre, my two CAD programs. I'd love to be able to modify these files, create new designs from them, etc. It seems like everyone uses a different file format and even when we agree on a common format, there's always one program that can't read what another has written, even in a cad neutral format. Cad Exchanger might be a way to alleviate these issues.

Any ideas or experiences?

Many thanks,

Bob
