Grasshopper - gradual cross-section

Looking for ways to adapt a Michell into having having inner members with gradually small cross-sections away from the root. Objective is to resemble a topology optimization as shown in attached figure (Michell_topology_result1.PNG).


Current design ( Michell_topology_tryout1.PNG) needs major improvement.

Current design is attached. (32.5 KB)
