Rhino and Archicad interoperability

Hi, so i have a question about the interoperability between Rhino and Archicad.
I modeled a complex curved roof in Rhino because i couldn't do it in archicad with shell or morph and i imported it into archicad to make the rest of the building but it it way more complicated to do walls this way because i can't trim them to the shell/ roof because it imported as rhino object. I tried using speckle to import it but it doesn't work, any way to convert the object to shell/ roof or import it as such? I will also atach a photo of the roof in question maybe you have sugestions on how to make it with shell directly in archicad.Screenshot 2024-12-14 160857.png

The only way I can see it turning into a shell if the surface is a ruled surface (e.g. hyperbolic paraboloid).

Refer to this article on how to create contours for Shells. You can use the AC-GH connection to generate the shell from Rhino based on input curves.

 

Then you could use it as a shell, but roofs won't work for such geometry.

 

If the surface is not that straightforward, you could try and convert it to a Morph, although I would advise against it, as curvature segmentation will result in quite ugly topology, you are likely to end up a lot of clean-up work (ctrl+shift left click on unwanted edges and set the visibility to hidden).

 

If you give thickness to your surface (either extrude it or offset the surface then close the edges with lofting or sweeps) and create a solid, you can use it for solid element operations.

Hi,

If you imported it as an object you can use SEO directly between it and the walls.
