Why is My Karamba3D Model View Broken?

Hi everyone,

I’m having a strange problem with my Karamba3D model and I’ve been stuck for several days.

I’ve built this type of structural model many times before, and previous projects worked without any issues. However, this time I can’t figure out what’s going wrong.

I’ve already:

  • Checked my previous working definition step by step.
  • Rebuilt the entire definition three different times, each with a different workflow.
  • Tried several possible fixes that I could think of.

Unfortunately, the result is always the same.

The confusing part is that none of the Karamba components turn orange or report any errors, so everything seems to be connected correctly. However, when I open Model View, the structural model is completely wrong. Members are connected incorrectly and the whole model looks broken.

At the moment, my best guess is that I may have made a mistake when connecting the points to the Mesh (or somewhere before assembling the model), but honestly I’m not sure anymore.

I’ve attached my Grasshopper file. I would really appreciate it if someone could take a look and point out where I’m making a mistake. If anyone has the time to correct the definition or explain what needs to be fixed, I would be extremely grateful.

Thank you very much in advance!

Hi, you need to check the units in your model, as it was set to m but I believe your geometry is in mm. Therefore the results were not correct

Thank you so much! You were absolutely right. The problem was caused by using millimeters instead of meters. After changing the units, the model works perfectly. I really appreciate your help. Thanks again! :face_holding_back_tears:
