Trim wall to roof / Grasshopper

[Nic Tulban]

Hello
Have anybody any idea about trimming a wall with a roof in the archicad-grasshopper connection?

Not sure you can inside Grasshopper but you can manually extract the settings of the wall and the roof, then recreate Rhino solids from the curves and settings extracted (thickness, height...) and finally split them in GH.

The solution is more simple than we think. Suppose we have a roof and a wall, both generated by Grasshopper. Even if the Archicad entities are locked by Grasshopper, it is possible to link them (in Archicad) using the 'Trim wall to roof' command. So the wall is trimmed, and it remains so, changing its shape accordingly, when we alter the roof parameters (for example the pitch).
The only disatvantage is that this interactions are not visible in Rhino.

Yes but you have to do it manually. It could be nicer to do them directly in GH but I couldn't find a way to transform AC entities into GH entities (BREP, solid or so...). If you know please tell me.

As far as I know at this point, there are no ARCHICAD Nodes in Grasshopper using which you could perform such operations between elements in ARCHICAD.

So... we are looking further!
