Remote Learning: The ARCHICAD Grasshopper/Rhino Connection

August 2 @ 1:00 pm - 4:00 pm

Course Overview

The Grasshopper – ARCHICAD Live Connection facilitates the exchange of geometric shapes between McNeel’s Rhino 5.0/Grasshopper and GRAPHISOFT ARCHICAD.  In this online course, you’ll learn how to use ARCHICAD’s Rhino-Grasshopper Toolset as well as the essential commands and how to translate a Grasshopper shape into an ARCHICAD model. Veteran ARCHICAD and grasshopper users can benefit from helpful tips and tricks that are not found in standard tutorials.

Grasshopper’s visual user interface enables the designer to use algorithms to create shapes that can be used as a reference to recreate BIM elements in ARCHICAD. The resulting parametric building has the potential to allow the designer to change the algorithm’s input parameters that will ultimately update the building’s form.

Learning Objectives

At the end of this session, attendees will be able to:

  • Start Rhino-Grasshopper and connect them to ARCHICAD
  • Use tricks and tips that can significantly optimize the use of Grasshopper
  • Identify the parameters that must be considered in order to model an editable shape/building
  • Create curves, lines, points, and surfaces in Rhino to be introduced to Grasshopper
  • Create parametric geometry starting from simple polygon shapes to construct a complex building in ARCHICAD
  • Design columns, beams, slabs, curtain walls and other construction elements directly from Grasshopper’s code
  • Manage and update the design of a building using the parametric code from Grasshopper
