I had to use it once to fix up a customers design, but there'd have to be a serious reason for me to do that again.
It really isn't suitable for "professional" design houses. Of the dozens of R+D companies I've dealt with over many
years, I've never come across any that use it. Maybe your best bet is to check what uni's, colleges, schools?
There are many that use it on this forum, so hopefully you'll get a better response. Good hunting.
