Cross-Section Optimization

Hi, 

Im trying to optimise a steel structure consisting of a number of UK Circular-Hollow Sections. 

Unfortunately I keep getting the same ERROR. Has anyone ever encountered this error before? if so what may be my problem? The Jpeg Attached shows my grasshopper script. 

Thanks in advance!

Tom

Hi Thomas,

do you use CHSH cross sections in the initial model? If not, the cross section optimizer does not know which cross sections to substitute for which.

Best,

Clemens
