- In this tutorial, we'll walk you through the setup, results, mesh, and then show you one way you can use the results to make a more optimized design. Make sure to download the "start" model from here to follow along (or use your own part with some slight modifications to the lesson):

Absolutely fantastic video tutorial. Thank you Matt and the Autodesk Fusion 360 team for bringing this to the masses. I can't wait to try this out sometime soon. Enjoy your day. Regards, Aaron (Melbourne, Australia).
Great to have a better idea of how to use shape optimisation, but that rule fillet command is so useful!
We really need to use that more often! Glad this vid helped!
exactly what I needed... The algorithm know me more than I know myself.
2:52 Nice how fast you skip over the expensive pricing for calculation and the non existing option to let it calculate locally instead paying your high price for cloud calculating.
You are awesome. I’ve been searching for this knowledge. Thank you.
Can you please do this magic to engine piston and piston rod. Just curious.
I have tried to do the same. Downloaded fusion 360 just yesterday, but there is no "shape optimization" option and no way to extract locally solved model (no promote button). Why?
The UI has changed so much, I am completely lost trying to replicate this.
Max- Yes, the UI has changed some, but all of the commands being shown are the same. I will mention it to the author and see if we can get an updated video made.
Please explain what those colours signify like how to know at what point to start removing materials?
The setup looks very easy to use. But why is it called shape optimiziation? It looks like a topology optimization.
Hey! For some reason the dropbox link for the part shown in the video is not opening up. Would be great if you could fix it! Thanks in advance
Hey, I can't access the link?
Menus do not match: "Promote" is not where shown
Thank you !!!
Very useful, thank you!
very nice video and very intuitive ,
May i ask a question ?
it seperates to to subquestions
a) in case of a part that rotates, the load direction changes , can we solve for all possible angles and load direction automatically ?
b) how can we determine if we apply force to one part of an assembly the load that is transmited to an other and extract that force and its direction and and then run the shape optimization ?
You would want to apply different load cases for part (a), but no there's not an automatic way to do this. You can run part (b) as an assembly, but you're forced to select a shape optimization target.
No no you didnt understood what i asked
for part a ) imagine we have a rotating part that lifts a weight , at 0 degrees we have a particular load pathway , at 10 degrees we have a different load pathway at 20 21 22 ...... the load pathway changes each time as the part rotates , can the shape optimizer give a solution for that ? so our part is strong enough in every possible angle ?
So for part b) it can be done but one study for each part and then the other , thats nice
Thanks for the answer
To load this in this way, you'd need to create load cases to represent all the different angles and force magnitudes. There's no automated angular range you can apply.
And for part (b), only one shape opt part per study. However you can include other parts of an assembly to transfer loads.
Thanks for the fast answer
for part a) is this feature available in any other autodesk software ?
for b) can this force be extracted as a vector ? I mean can the resultant forces be displayed for each part?
In Inventor you can use a similar algorithm to optimize. They also have parametric studies. knowledge.autodesk.com/support/inventor-products/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/Inventor-Help/files/GUID-10B9D76C-608C-4464-9A47-B9FE61B5771F-htm.html
What I can't confirm at this time if you can do a shape optimization AND parametric study together.
You can use resultant forces to extract reactions as vector.
Dear,
Is it possible to define for instance 3 different load cases (the mechanical component will operate in different modes) and run the shape analysis considering all the three load cases? Or do I have to run it three times separately for each load case and then combine it in my mind during modeling the optimized model...plus test it for static analysis afterwards. Thank you in advance
Three load cases will give you the best results, for sure. Running three times and trying to combine would be a pain! To test after you'll need to convert a mesh to solid.
@@adskFusion So it is possible to run one topology optimization which takes into account multiple load cases, right? So the resulting shape would work ok for each load case scenario separately..
Can I do everything on Fusion 360 on the student version? Any limitations?
There are limitations related to generative, but other than that you should have access to everything else.
I read somewhere that you can optimize the output mesh for 3d printing or CNC. Do you have any idea where that setting is? Thanks
Not sure what you're referring to. Sorry about that!
A little bit late but i saw this video too
th-cam.com/video/3smr5CEdksc/w-d-xo.html
It appears that the finer you get with the mesh the smoother it gets for exporting it as a 3d printable file
Is it correct that shape optimization is not free anymore but costs 5 cloud credits now?
Correct; shape optimization solves were free only while it was in testing. See here for more details: knowledge.autodesk.com/search-result/caas/CloudHelp/cloudhelp/ENU/Fusion-Simulate/files/GUID-6A3A1888-357D-4006-A01E-D18122DB8AF7-htm.html

which course is this in autodesk academy?
i can't solve the simuilation, the thing is greyed out
Great
when i click on solve 1 study, the task is failed. how can i get it completed?
Mine failed as well, look at your target. For example mine was set at 30% mass which wasn't enough. Once I raised it to 50% it worked just fine!
Hey there, I don't know if somethings changed since you posted this but when I open the .iges and save it as a fusion project and then attempt to go to simulation it crashes fusion 360.
I just tested this, and didn't have the same experience --looking at results now. Can you try a different simulation on a different part?
My apologies, it appears that my installation is pooched and won't even open the simulation workspace.
Reinstall fix it?
Haven't tried that yet. My system is fully locked down so my user ID can't screw anything up. So I'll have to wait for the help desk to reinstall
The problem I see is that your "optimal" shape was greatly influenced by your initial shape, NOT just by your load case.
It's not a problem.. that's the way we design. The other way is using generative design AI to come up with new models, but that's entirely an artificially simulated process.
6:35 Rule Fillet
I love these videos, but how about a quick rundown with un-needed. information. Go through all the Let strokes with minimal information, then review it step by step. Too much information to take in on some of these videos and the viewer looses track of the steps. Less can be more! Love the videos none the less and they help a lot! I'm self taught on fusion 360 through "youtube university" and cant thank you guys enough!
This was a combination of two seperate videos. I believe that's why the presenter did a rundown of upcoming goals at the start...and perhaps in the middle as well.
Wow! :)
6:42 f in the chat lol
