This form is more an artistic sculpture than architecture - and archicad is an architecture-program, not a sculpturer like rhino.
Beside that, it should be not a big problem to devide this very complex form into pieces and form this in Archicad mostly with the shell-tool and the morph-tool.
but its a lot of personal work and detailing necessary - because there are no automatisms for connecting round forms together. Later when making this real in a building-, you will get big problems detailing water-removal, thermal connections and so on.
First - you have to set the exact gepmetry parameters.
You need the radiusses for all Archs, define all hights of the conection points and then you form the pieces.
There is a great temptation to use the morph-tool in such situations but later you will get problems with that. Better use the schell-tool because this is an architectural element - morhs are not.
