How to edit window 2D Cross Section Preview?

Leonardo Lopes — Wed, 27 May 2026 12:16:49 GMT

Hi everyone,

I am working on a C++ plugin and I'm trying to automate the modeling of some lines and dimensions directly onto the 2D Preview of window cross-sections within a Schedule.

I am having trouble finding a way to access this specific view. From what I’ve explored in the API documentation so far, there doesn't seem to be a direct way to retrieve it.

Could anyone guide me on whether it is possible to access, obtain, and modify (specifically drawing lines and adding dimensions to) this 2D preview view via the Archicad API?

Thanks in advance for any help!

Operating system used: Windows

Hi Leonardo,

Unfortunately there is no access to the Interactive Schedule via the API.
I've asked this Graphisoft directly and they confirmed the lack of access.

Notably, the Interactive Schedule is programmed as an Add-On (check the Add-On Manager). There are mechanisms to expose functions of an Add-On to other Add-Ons, but it's more awkward to use. Might be one of many reasons why they haven't supported this yet.

Best regards,
Bernd

Hi Bernd,

Thank you very much for the response!

It's a pity that this functionality isn't available in the API yet, especially since automating these preview details would be a huge time-saver. That insight about the Interactive Schedule being programmed as an Add-On makes a lot of sense as to why it's so restricted.

I really hope Graphisoft considers exposing these functions or implementing direct access to it in future API releases.

Thanks again for saving me from hours of chasing a dead end!

Best regards,

Leonardo
