Not to hijack, but what file extensions did ideas use? I searched on .XPK and didn't find any.
We briefly had an Ideas user in the early 2000's when SDRC bought the old Camex Cammand software and we were upgraded to Ideas via Maintenance agreements at the time. Some of that tooling is still in use and record keeping from that era was lax. The Ideas user wasn't here very long and i'm sure most if not all the files were converted to CatiaV5 and once UGS took over Ideas, we let it expire.
