Cross section optimization by iD's element in c#

Grasshopper Karamba3D
1

Hi everyone

I try to create a workflow to optimize wood cross section by the id of element. For that, I’m using the Karamba library in c#. I made a test but it looks like cross sections of the model are not updated during the optimization. Can someone help me with that ? I attached my grasshopper file and my csv cross section files to run the workflow.

Thanks

Hi @Augustin_L,

I cannot run your definition - the script throws an exception. What version and build of K3D do you use?

Try to debug the script using a cantilever with only one beam.

Does the scripting example work for you (see here)?

Hi Clemens,

I’m using the 2.2.0.17 version of karamba3D for rhino 7. For my side, the script doesn’t throw an exception. The script runs but there is a warning :“you may need to provide a runtime policy”. Here, I attached my cantilever beam example.

Hi @Augustin_L,

I think you forgot to add the updated beam to the model:
cantilever_beam_cp.gh (45.6 KB).

The warning is due to the fact that your version of RhinoCommon.dll is newer than that used for compiling Karamba3D. I haven’t found a good way yet to get rid of that message.
