Wall Interface with Roof

[Anonymous]

Hi there,

I am new to ArchiCAD and I have some issue on creating walls. It maybe quite basic so hope someone can help me out with it.
I am trying to use grasshopper with ArchiCAD connection to build a parametric house. I found that when I build a wall and roof, there will be a triangular hole between the wall and the rood (see Wall 01).
I would like to know how can I use the basic wall component to fill the hole. The first idea comes to my mind is to extend the wall a bit higher then use the bottom of the roof to trim the wall. But I don't know how to do this 'trim' in grasshopper... Another idea is to build 2 trapezoidal wall to fill the hole. But I also don't know how to create a trapezoidal wall, the two ends of wall seems always restrict to the same height in ArchiCAD...
I know that you can use the morph to create whatever kind of shape however you cannot apply window or door on it if it is not a 'wall' object.

Something you need to be aware of is that the Grasshopper-ARCHICAD connection is a relatively new development so it does not offer all the capabilities of what you can do in ARCHICAD, including element Connection commands.
One possible solution may be to create a Complex Wall with the exact section profile you need (slanted top) and then use that Wall type in Grasshopper when generating the Wall.

Otherwise you would have to trim the Wall with the Roof in ARCHICAD.
