Hi people !After public request, you can now use FsRegen to modify the GUIDs of existing objects. Why ? To make them NOT working. Why ? So you can make objects with the same GUIDs as the ones you change, replacing all objects of the standard library to your liking...BACK UP YOUR FILES FIRST !! FsRegen automatically does it for you, but since it's alpha I would be cautious. I tested it on my systems, but you never know....Another thing that slipped my attention was that the MS libraries increment the FIRST two segments of the GUID for successive objects in a library. Do the same with your libs. The increment button changed to conform.Click on the blue version number of FsRegen main screen to go to the web page :-)For those of you with older versions : www.nhreas.com/fsregen.htmlHope you like it...P.S I haven't tested it with the latest makemdl.... I hope they haven't changed things dramatically. I couldn't take another code rewrite right now.... that would be the end of it...George
