In this article I will be focusing on a simple example to demonstrate RH-GH-AC live connection, another wonderful OPEN BIM workflow from GRAPHISOFT. We will start with an input from a ARCHICAD (AC) file and based on that input a set of balconies will be created using Grasshopper (GH) which is running on top of Rhino (RH). There is not much use of RH but we need Rhino to run Grasshopper.
Make sure all the three applications (AC, RH and GH) were installed along with live connection add-on from GRAPHISOFT running.
Refer to Grasshopper ARCHICAD Live Connection 1.5 User Guide from the following link:
Chapters to focus:
- Getting Started
- Launch the Applications
- Start the Connection
- Grasshopper Palette in ARCHICAD
To understand this exercise there is a need for basic understanding of Grasshopper. Please refer to the following links:
Input from AC
- In ARCHICAD create a simple building with 10 Story + Roof. Set the Story to Story height as 3000 mm. Create a Complex Profile for the railing as well. Alternatively download the file from the link here.
- Use Line tool to draw a line from point P1 to P2, suggest to draw the line in 2nd Storey.
- Select the line just drawn using the Arrow tool.
FuturArc features an article in its current issue on GRAPHISOFT and the BIM approach of the company. Furthermore you can read how its products fit into the OPEN BIM workflow, why it is focusing on ARCHICAD instead of covering all AEC disciplines with one single solution and how the licensing policy will affect the upcoming years.

Continuing the previously started thread of highlighting elements with certain properties in ARCHICAD for BIM submission to BCA (Singapore), this post will present another way of showing the above mentioned using the Building Material properties and Pen Sets.
Fire resistance is in close connection with the materials so this method provides somewhat better control and automatism then using the Mark-Up Tools.
We can create a pen set that we use for representation without the highlights and a different one for the highlights. The biggest advantage of using the different Pen Sets is that we can store the chosen option in the Views.
One of the key submission issues to BCA in Singapore is to highlight the elements by certain properties. While it can be easily solved in Revit by setting Filter Rules (in details here) or using the Color Splasher add-in it needs a workaround in ARCHICAD as for now, but thanks to the increasing demand for the feature this will probably change soon with one of the major updates of ARCHICAD. Until then, don’t let this stop you from using it if it suits more your design needs as there is always a solution!
Elements highlighted in Revit
In case you came across the term BIM recently you have probably learnt its benefits by now but might find it hard to start with. There are endless number of blogs, forums and threads all around and it has been an ongoing issue on ARCHICAD-related media as well recently, not surprisingly. Although it seems to be an infinite topic, the framework can be defined quite simply.
