Good day
Looking to do a hobby project for my vintage rc car.

If not anyone know any apps that might do this?
Fusion 360 If I understand cannot do this in the free version
Freecad seems not ready...

even one in 2d only will work
any other known options?

Tnx.

Do you mean something like this?

I should have been more specific.
Topology optimization for engineering purposes... https://www.youtube.com/watch?v=hAGFkWkqocI

I found a simple 2d one that I am going to try out https://www.topopt.mek.dtu.dk/apps-and-software/interactive-2d-topopt-app

Tnx.
