record cross section changes

hello everyone !!

am new using karamba and grasshopper ,currently i am working on a project of dome structure ,first i optimized my cross section and then i run galapagos with setting up minimum mass as fitness function and genomes are the subdivisions of my mesh panel .
i have got the min mass with the optimal subdivisions but my cross-section has changed , so i want to record them in order to set am optimal subdivisions with their cross section ,is there any one can help me ?

thank you in advance !!
