Link Connection between Archicad and Grasshopper

Although the model in Rhino can also be directly imported into Archicad, the model thus completed cannot be edited in Archicad. Because it is based on GDL. In order to realize batch operation to save time and facilitate modification at the same time, you can directly use grasshopper and Archicad link plugin to complete Archicad modeling in Rhino.

0. Install related plug-ins.

    That is available on Archicad's official website, but pay attention to version issues, and the Rhino version of Archicad 23 link must be after sr14. Because I do not want to reinstall Rhino (can not be upgraded normally), I chose to link with version 22.

1. Draw the reference line 

    Draw the lines according to the original drawing or cad. The wall should be a single line, select the center of the reference line. The floor needs to be a closed curve. The column only needs the center point.

2. Set the grasshopper file. 

    There are ready-made calculators, which can be set directly. There are two methods to modify the settings. One is directly in grasshopper, but it is not easy to modify the settings as there are some missing options. Therefore, I chose to draw the desired wall in Archicad, and after changing the settings as I want, connect it back to grasshopper as reference to the calculators.

3. Start the connection

    Click the button. It will be displayed in both Rhino and Archicad windows

4. Add windows and doors. 

    As the specific framework of each window is not the same, even if it is all built in grasshopper, it needs to be modified one by one in Archicad. So I choose to manually model in Archicad directly. If there are many windows or doors that are all the same, I will choose to use grasshopper. The surrounding building is an example.

5. Add furniture. 

    At this point, grasshopper cannot be completed well, mainly because GDL is connected to the object. It is more convenient and quick to add it directly in Archicad.

Ex. Roof.

     There is a very convenient modeling method for the roof, you can directly change the flat surface in Rhino to the single-sided roof in Archicad. Because I have no roof in the modeling part this time, it is not used.
