I need to bump this one back to the top . . . it's been suggested and discussed ad nauseum, so it is difficult to understand why we haven't heard definitive anything on it from Alibre . . . or maybe we have and I missed the memo? . . . this is easily the single biggest complaint that I have with AD . . . and if I might be so bold, I would submit that this single feature (or, rather, the lack thereof) will do more than anything else to prevent Alibre from growing in the "real" CAD world (where multiple designers working in the same shared server-based repositories are the norm).
We almost didn't buy the software last year because it lacked true sharable repositories, but like so many others we fell in love with the price . . . we saw all of the improvements that Alibre was making and thought that surely this would be one feature that would be added soon . . . but now with all of the hassles we've had it doesn't look like such a good deal any more.
Knowing what I know now, AD would still be my first choice if I were a single consultant or needed a stand-alone CAD station. However, if I had to go back and make the decision for a new CAD system for my company, I don't think I would choose AD again.
