Hi MojaPana,

Yes, I support Rhino 6 and Rhino 5.  I'm still building the installers for v6, if you message me with which ones you want I will send you links.  I'll update the downloads page ASAP.

Does GeometryGym work with Rhino 6 ?

Hi Siong, 

Can you describe the issue you see with windows?  I tested your file and it seemed to work ok for me. Please start a topic (or add to an existing) in the discussions rather than comment.

There is an adaptive component example if you browse here: and then into sub folders Samples, BIM, GHtoRevit, adaptive components

Hi Jon and everyone,

I have an issue creating a Revit window on a Revit wall with the Geometry Gym plugin. Not sure what I am doing wrong. Hope you can advice. Attached is the GH file.

In addition, it would be wonderful if you can provide an example of how to create adaptive components with the GeomGymRvt components. I have looked at the existing examples on Github but could not find an example with adaptive components.

Hope to hear from you.

thank you and best regards

I am pretty new at using geometry gym for GSA structural analysis and was wondering if there is a way to query modal frequency

Any Archicad user with a bit of experience with AC-GH Live Connection ?

Hey guys, ive been trying to use GG plugin, unfortunately I am an architect not a structural engineer, no clue in how to know what each section in the catalogues is shaped like, how can I find out this ? is their a PDF catalogue ?

my 2nd question, how can I create a custom profile to enter in the GGsweep ?

Comment by Morten Ydefeldt on January 23, 2017 at 5:20am



As you can see from these two geodesic domes it seems like it can be created with two different permutations.

The geodesic dome which I am able to construct in GG is the 'wrong' one, I want the edges of the pentagons to be parallel. I believe it's a question about how the base icosahedron is flipped when the dome is created, is there a way to construct the right geodesic dome from your script?
