Rhinoceros - Grasshopper - ARCHICAD tutorial videos
This video clip shows how to create a free-form surface in Rhinoceros, which will subsequently be transformed to an ARCHICAD Morph element by using Rhinoceros, Grasshopper and ARCHICAD. The new connection between the applications offers bi-directional geometry transfer. The basic geometrical shapes created in Rhinoceros now can be translated into full-fledged BIM elements in ARCHICAD while adding algorithmic editing functionality thanks to Grasshopper.
