I am a first time user to ArchiCad (I have Ver 9) and have been getting around pretty well until I decided it was time to add to the library of GDL Objects and Materials that was provided with the software. I have a ton of stuff I have scavenged from the internet from vendors and have no clue as how to add them. I cannot find anything in the learning materials provided nor the Training materials that just says "To do this ..... First click here... Then do this..." I have a bunch of GSM and LWA files but absolutely no guidance as how to add them. If anyone can help please respond to post or email me at msantacroce@hotmail.com. Thanx Much.
