Custom made GDL objects from Archicad 27 can't use the MVO settings in Archicad 29

[Andras Bognar]

Somehow, our custom-made GDL objects from Archicad 27 can't use the MVO settings in Archicad 29. They were ok in Archicad 25 and 27, but not in 29. Not sure what I need to change in the Master Script and the Parameter Script of these objects to be able to use the MVO 2D and 3D detail levels in Archicad 29. Some of them are made purely with the Library Part Maker 25 - 27, some of them by Param-O 25 - 27, with a little bit of a tweak in the GDL script (Master Script and Parameter Script).

Operating system used: Windows 11

Hi Barry, I think I got it now. Yes, that is the 4th option. I am not sure how the file will behave if we go on that path, though. Do you have any good or bad experience with such a solution?

Not really as I am not using 28 or 29 yet.

All you are doing is using the new software but with the old libraries you are still using the old Model View Option settings.

So long as you don't try to load the 28/29 library packs as well, you should be able to keep working on those old files as they are, just with a newer program.

Don't mix the old and the new libraries, that is when it becomes complicated.

Barry.

Not sure why Graphisoft hasn't documented this.  They doubled my yearly cost but leave me guessing. I sent a request to tech support and they said to check the forums.   I am loading a new library for 29 so I can update my custom objects as needed for new requirements.   Now my doors, windows, and lights that use the MVO settings are not displaying.  I'm not happy.
