Rendering wall with different heights or slopes

roni — Mon, 16 Sep 2024 11:17:09 GMT

Hi Team,
I was trying to render a wall using archicad CPP API's with different height on top or wall having slope. I had added the screenshot of what I'm trying to do.
What I had tried
1. SEO - Was able to do place a morph element above wall and do SEO in Archicad UI. This was successful in Archicad application but was restricted in CPP API's. From this doc, https://graphisoft.github.io/archicad-api-devkit/group___element.html#ga1a5d9501241379e03fb90fd8137a5b5a only two morph elements can be used for SEO operations. (or Archicad were yet to expose the wall <-> morph SEO API).
2. Using morph element - Create the shape you wanted using the Morph element. This approach won't allow you to convert the morph to wall element. (Other way is possible). And if I choose morph I will lose wall properties.

Is there anything I should try?

I am not a programmer, but normally, when modeling in Archicad, you can also achieve this by placing a polygonal Opening into the Wall; the shape of the Opening will cut off the top of the Wall, achieving the desired geometry. It is better than using a Morph because the cut is automatic (no need for SEO) and the Opening stays associated with the Wall so if the Wall is moved, the Opening goes with it.

Hi @Laszlo Nagy
Thanks for the response, I had tried same, so far I was only able to create rectangular openings via CPP API's. Only able to create freestyle opening through the ArchiCad application directly.
Is there any way to create freestyle or polygonal openings via CPP API's?

Regards,
Roni Vincent.

Sorry, I am not a programmer or developer, I am not familiar with the Archicad API so I cannot say.
