Layers. Flexystruder

Hi guys, not sure if I’m posting this in the appropriate place, but I’m new to making/modify designs, I need some help learning how to make thicker layers at a specific place in a design. Is there a video I could follow? Or would someone be able to tell me the steps? Thanks

This can be accomplished easily in simplify3d and prusa slic3r, maybe new version Cura can do also I’m not sure. But in old version Cura it cannot.
