Thanks in advance, I am archicad 18 (A 18 ) user, in a prolonged time ahead I will be working on A10 files in which 99% of windows, doors, and objects are from A9 Library . Does anybody have any experience with implementing such an old library to A 18. I have gathered some information, “pick and inject” method works, but is time consuming. I downloaded A9 library from a help site, so I have it in one file, but will it be accepted and adopted to A 18, that is the question. If it is possible, how to do it and not make the main libraries messy. By the way, I haven’t imported any libraries (old or new) to archicad so far, so please - some basic tips.
