I am posting on behalf of a user from another thread (
Wish list: it would help if ArchiCAD could give me information on specific pairs of duplicates, with the file path for each. That way I could better track them down without going into the arcane world of library part creation.
I believe in general the idea is that the Library Loading Report should give a direct mechanism to correct Missing and Duplicate objects. Right now the Library Loading Report is like a Check Engine light on a car. It says something is wrong but you must then use the information it gives to then resolve the issues elsewhere.
Please post here to add more comments and weight to this wish.
