Every add-on can save custom data into an Archicad single project, teamwork project, or hotlink module. This lets the add-on programmers have a custom – unlimited length – data section in the project. The benefit of this feature is that it spares the Archicad users from having to care about many separate files that belong to a project and are needed by add-ons, when the project file changes its location (by copy, paste, email, ftp, etc).
The custom section of the project file can be anything the add-on programmer desires to save for his/her add-on, but special attention is needed for the issues of maintaining this data when the add-on is active, and also, the correct byte order, if the add-on was developed for multiplatform usage.
More information on this topic can be found at the description of the ModulData Manager.
Trick: You can delete add-on data from a project file following these steps:
- 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.
Warning: The data deleted following this method will be lost and cannot be recovered!
