Thanks for your bug report. I will try to fix this as soon as possible. --Clemens

Dear @MCFormatEng, I could not reproduce the bug. Did you use the latest build of Karamba3d from here? The display of springs (see here) is special: they show up as beam pieces of length 1 meter. The reason is to make it possible to deal with zero length springs. -- Clemens

Hi @Clemens-Preisinger,

Sorry, you are correct, I hadn't updated to the latest build and doing so fixes the issue.

Thank you for you help, Matt
