Karamba: cross sections has to be bigger than the biggeste family member

1645 cross sections need to be bigger than their biggest family member.

Just no, I do not understand what it means nor do I understand what to do by reading other fora.
What am I doing wrong?

Thank you for your response. :slight_smile:

Hi @ForestOwl, you need to increase the range of cross sections used for the cross section optimisation. The cross section optimisation is giving feedback that there are still overutilised elements in your model. Your current setup involves a two 15x40m concrete plates supported only at one end - please also check if this is accurate. You can refer to the Manual on our website for further information.
