Hi!I noticed that on the czech version of this forum a discussion was going on about ProdLib and the general structures library.Somone said that they were missing connections.I invite you all here to take a look at the library and suggest possible additions you would like to see to it. We are still working on that specific library and would like to develop it in such a way that it is actually usefull for you!You can get ProdLib here: http://www.prodlib.com/download
