Yes Andras I get what you mean.
And I agree that one software will not fit all, and that wouldn't even be positive if it was possible.
But what I mean is not to use Archicad to make prototypes for CNC.
GH is not about making prototypes, even if Rhino is widely used in indutrial design.
The way of working with GH would be interesting for conceiving architecture in Archicad or revit too.
It is not about producing CNC files, but in the way of arranging the geometries in algorithms.
This could be used for building, facades but even for urban scale.
That is the way lots of architects uses Grasshopper, and Archicad could very well fit as a frame for such "tooling"
