That looks so great! It is very similar to what I am trying to achieve with the node editor random building generator that James has so kindly put together. There are some great examples here. I'm fascinated by the amount of traction Blender is starting to generate. It seems like it's becoming quite a serious contender for some of the bigger software companies, even with their software being "industry standard". I definitely need to learn a bit more Blender, but I just love the smooth simplicity of MoI. It's such a pleasure to work with.
Fluent 1.5 Power Trip , a unique addon for hard surface modeling and much more (thanks to Rudy an amazing french developer).
Fluent does not offer a compilation of tools but a global workflow to help you in your hard surface modeling and realizations.
This global vision allows the creation of smart tools. Make cuts, add plates, cables, pipes, grids and fabric panels (Quad Remesher or Instant Remesh needed for the cloth panel).
But above all, finalize your model with tools to fix errors generated by Boolean operations.
