algorithmic modeling for Rhino

Hi all Karamba users,

I've been discussing with Clemens (and advancing on) a utility to extract the Karamba Structural Analysis model so that it could be verified or advanced in alternative commercial structural analysis software.  I know that Karamba can presently export to RSTAB, but I'm working on enabling this further for a wider range of software.

At least initially the primary options are the software that I have developed plugins for.  This includes Oasys GSA, Autodesk Robot, SAP2000, Sofistik, Spacegass, Strand7/Straus7 and hopefully shortly SCIA.  The way this exporter would work also means that any structural analysis software recognizing the structural analysis aspects of IFC could also be utilized.

At present I've developed various plugins to allow user generation of model data from grasshopper, but a Karamba exporter would allow users to operate entirely in Grasshopper for initial design, but then automatically extract the model without rebuilding all the components with geomgym equivalents.  This would permit verification of the model results, and often projects have mandates on using specific (often certified) software for detailed design calculations.

If you're interested in participating in the early testing and advancing of this feature, please post here or get in touch.

Hi Jon,

I have tried your new building but I have noticed that it work if I previously open a simple file that I created.

If I try to export for first a generic file downloaded in KARAMBA3D, new build doesn't work!

Below the image of some error.

have you tried to export these file in sap2000?


Sorry, this time you're going to have to explain in more detail the error (or how to produce it).  I tried importing the ifc file you attached and it seemed to work fine for me.



Hi Jon,

I tried to build a new project and the importer finally work fine.

The only things that don't come imported are the release.

It's not a big problem but I want to say its so you could improve your fantastic plug-in.

Thanks a lot,

Hi Jon, i have this error coming out of ggKarambaexporter component:

1. Solution exception:Could not load type 'System.ServiceModel.HttpBindingBase' from assembly 'System.ServiceModel, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

i'm in karamba 1.1.0

Thank you,


Hi Bruno,

There were a couple of changes through the WIP of v1.1.0 Have you downloaded the latest from  ?

Let me know if that still has problems.
