Thanks for such a great response! I gather you lean towards the first.
-I got as far as open object. in the open library part window i have two choices. -embedded library, which is default. this has no options to move forward. nothing to select, the open button is grayed out. -the second, browse for a folder, allows me to browse into the ArchiCAD library 15 , but after browsing a while, i have no idea where to find the actual object files.
thanks again.
