Importing things from elsewhere, even like ever popular EAGLE CAD, is extremely frustrating. The forums are full of workarounds that don't really work, promises of coming features, where the promises are more than 2 years old, and various unanswered questions.
I've spent the last couple of hours trying to figure out how to import a single part for which the manufacturer provides EAGLE .sch and .brd files. So far, I cannot get that part into a form where I can use it.
Honestly, is someone actually working on these things, or should we just give up hope?
