I reeeeely hope its not possible to read Moduldata from another Add-On 😄
"Data sections are identified uniquely by the add-on’s modul ID (‘MDID’) and an optional modul name string. This means the one data per add-on limitation of previous versions has been dissolved. "
since you cant start two add-ons with the same mdid id, this should be impossible.
i did not try it but my understanding ist, that modul data is saved in a file that is in the add-on folder. theoretically you could write your own interpreter of that file... would be a awful hack but could work.
the documentation states about deleting old modul data:
- Quit Archicad if it's running.
- Delete or remove the add-on from its location.
(Usually the Add-Ons folder of your Archicad installation directory.)
- Start up Archicad, and open the Project file in Archicad that you want to erase the add-on data from.
- Locate the "Archicad Temporary Folder"
(It is on the Temporary Volume, which can be set through the Options/Preferences/Data Safety menu, Temporary Folder Location button (or the applying localized version of it.) Usually it's on the C: drive on Windows, or in the System Folder of the System Drive on the Macintosh.)
- Switch into the
APIData subfolder.
- Locate the tmp file that belongs to your add-on.
(The corresponding file should contain the filename of your add-on at its 64th byte.)
- Delete the located file.
- Save the project in Archicad.
but like i said, that would be an awful hack...
if i had to implement a datashare between two addons i would do one of the following:
1. Make that the addon looks from the outside as two addons and are in fact just one apx
2. use the communication manager to send data between the two add-ons.
Important: Moduldata ist legacy. You should use AddOnObjects!
from the documentation:
"This is a legacy technology, please use Add-On Objects instead."
