Fusion 360 Form Mastery Part 48 | How To Model A Toroidal Prop Using Forms

- In this video we are going to hop on the toroidal bandwagon and take a look at how easy this is to do with Fusion 360 forms. No need to create a lot of sketch planes, profiles and lofts. Just build out the shape in 3D.
If you are brand new to forms I suggest having a good grasp on the basics first which you can find earlier in this playlist, but it should still give you a good idea on what is possible.
while the exercise in forms is appreciated, please note that the shapes and angles of such a device matter tremendously.

Great point, I pinned your comment.
After expending 3 months of watching this playlist and following up with Fusion 360 a side, I just wanted to say thank you so much for your time doing this Fusion 360 master form video series
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!
The leading edge should be thickened to generate lift, not the trailinng edge !
wow really useful tutorials, thanks!
Glad it was helpful! Thanks for watching.
Hi good day, I've been learning a lot from your channel, I'm new to fusion 360. I've been following your car sketch videos and I am getting a lot of trouble with modeling my dream car, the Datsun 240z. If possible in the future, can you please upload a demonstration video on how to go about modeling this car? Thank you in advanced for taking the time to read this message :)
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 :)
Truly amazing video on how to do this the easier way!! A question I would have is, would there be a way to make it parametric, for example the pitch and some angles, that you would just type that in and it would adjust the shapes? Also, Is there a way to start of from the edge of the cylinder with a hydrofoil shape (wing of aircraft, seen sectional) and "extrude" that out in that loop shape you did? Thank you very much!
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
What would inform the design aerodynamically? Was MIT's process iterative?
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.
Amazing Vid dude! Easy to follow and with the instructions you can definitely make your own version!
Glad to hear it!
Always on point. Great video, awesome timing as always! Thank you!
You are so welcome. I figured everyone would be trying to model these things lol
Bruh 🤯 thanx for introducing me to forms. It’s like ZModeler from ZBrush
Yeah its a nice mix of mesh modeling and CAD. There are lots of form videos on this channel to pick from ;)
Dude. The timing on this is incredible. I've been trying to figure this out for about 45 minutes and you uploaded an hour ago.
Thank you so much!
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.
