Hello!
I've made som really great looking GDL objects from the .dwg objects that Bang & Olufsen provide. For example I've made the new great looking Beovision 7. There were some problems with the objects that I had on my site before but it should be fixed now and all the materials should be rigt!
Go download at
web page and click att GDL -objekt
PS. if the materials dont show right, just right click on the object in archicad and choose "use objects materials"
