Another problem of @donaldshimoda is that he runs nightlies. Nightlies require a deeper understanding of the software then a stable release. (There is no documentation and if some major change is made it is not communicated for simple users. I am not so sure this fact is well communicated by the kicad website.)
Facts are i use nitghies, libraries are pretty broken (because are nigthies as Rene states here) and finally: i dont care that dont work, I already say was not a problem for me. If you fill bad about the fact that dont work is other problem, not my problem. Is ok, i know what implies use of beta software , dont need to read a document expolaining that because im a software developer also.
Thanks for all the information. Is clear the problem is im using beta release (or aplha) and the only problem i have is 3d models. Is trivial, in any case.
