FYI
Hi Steven,
Ricardo let me know you called with an issue about MU windows in ARCHICAD. There is a known issue where you cannot set the number of Horizontal or Vertical units in the new interface. Sorry for the inconvenience. Out product team is aware of the issue and working on it along with other library issues to create a Library Update. There is no ETA a of yet.
For now you may load the ARCHICAD Library 18 alongside the ARCHICAD Library 19. Go to File > Libraries and Objects > Library Manager and click the "Add" button. Browse to the ARCHICAD 18 folder and highlight the "ArchiCAD Library 18" folder and click "Choose". If you are asked to Consolidate, choose "Load Anyway" instead. You will have duplicates, but the ARCHICAD 18 Windows will function as they did before and the other ARCHICAD 19 windows will still work as they are designed.
When a Library Update is issued from GRAPHISOFT, you will see a notification to download and install the update. Then you may then simply use the "Migrate Libraries" button in the Library Manager and all duplicate objects resulting from the 2 side by side libraries will be cleaned up at that time.
Best regards,
