Great point, I pinned your comment.

No problem! are you doin this with forms or just modeling it?

@@LearnEverythingAboutDesign I was trying to model but using a form has been WAY easier and makes iterating on the subtleties of the blades practical.

1000% I certainly like to convert the form then pattern and hop back into the form to get a good idea where the blades will be. I might do a more advanced version of this as well using circular symmetry in the form, but not as a first pass.

You're very welcome! This series was a bit slapped together every time I thought something needed to be added. Glad you found it useful and helpful!

Glad to hear it!

You are so welcome. I figured everyone would be trying to model these things lol

Glad it was helpful! Thanks for watching.

Yeah its a nice mix of mesh modeling and CAD. There are lots of form videos on this channel to pick from ;)

old Z cars are one of my favorite! If i get the time I would be happy to! It is important to know that Fusion isn't really a car design tool so it isn't the easiest one to use :)

Thanks! Parametric and forms is tricky, but there is a tool called "Match" that has an associative option. so surfaces, sketches etc that are updated in the design will update the form. This works BUT it only moves the edges that are associated. So if you have a lot of division it can really mess up the form. To do a torioidal prop like this with parameters would be possible but a much longer process. You would need to define the cross sections at various planes. I would generally start with a curve for the "path" of the prop blade, and then make planes along that curve so they stay normal to it. With care you can drive it with a few parameters. For the hydrofoil shape and extruding yes. Forms is a direct modeling approach with no history. You can start a form from a sketch, so if you bring in a profile of a foil you can use that as the start. Word of caution though unlike solid and surface extrudes, sketch based forms are approximate. Their accuracy varies based on the number of sections and so it will never be an exact match to a mathematical profile of a wing.

thank you very much! Very challenging!@@LearnEverythingAboutDesign

So Fusion sadly doesn't have any CFD, and generative design fluid is only looking at a single internal fluid path. So if you were to do this in Fusion and want to work on optimizing the design you would find a starting point and test it with CFD then iterate from there. I haven't seen any papers on how MIT or those before arrived at their optimized designs, but there have been a few videos showing 3d printed ones and looking at cfm and use fog/smoke machines to look at the flow/turbulence of the props. I think an SLA or mSLA machine would be ideal for this sort of testing.
