Optimize cross section without editing material

Hi,
Im optimizing the cross section of my model, but I cant seem to prevent the OptiCroSec component from changing the material. Is it any way to make it not change the material?

Hi Sigmund, the optimisation component does not change the material properties, but selects from the different cross sections you have defined. You need to make sure to define a “family” in a cross section so that the cross section optimiser only selects from the set of cross sections you defined.

best,
Matthew
