How to get module data created by another Addons?

If Addons A create module data name 'AA' in project file P, then can Addons B in same file project get module data name 'AA' with ACAPI_ModulData_Get()?

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."
