There seems to be a bug with Karamba 3.1.4 visualising the Beam loads in the model view component. When the Geometry Input Units is set to m then everything looks fine. But if it is set to mm then the load annotation for a beam load goes to infinity. See screenshots. In the first Rhino and Karamba units are set to meters. In the second Rhino and Karamba are set to mm. Everything else is equal. The geometry is appropriately scaled for mm in the second file. The displacement from the Analyze component is the same so it appears to only be a visualisation issue. It also seems to only happen with a beam load. Mesh load set to generate Line loads looks fine. I also attached the two GH files.
