Even though you have a small library of videos, you are definitely my favourite F360 creator. You have a very nuanced understanding of surfacing that I have not seen from other creators. Learnt a lot from this. Thank you.
Most people who make tutorials are other hobbyists and lack the technical foundation. Even many of the Autodesk guys who make tutorials don't have that foundation. Surfacing to G3 and often enough even G2 is really not possible in Fusion 360 except in very isolated cases such as to flat surfaces. The limits of the geometric modeling kernel (ASM) can clearly be seen in the later part of the video (see curvature combs) when there appears to be a need to break up a simple loft into two, additional rails etc.
As a person comfortable with F360, yours and Fusion 360 School's tutorials are the only ones from which I still learn new things. Thank you for sharing this with us, keep up the good work!
Your videos are so helpful, thanks!! You should really keep making more, your teaching is one of the best for fusion on RU-vid. I look forward to seeing more!
The third order derivative is great. Above second order can be used in aerospace activities. It’s difficult for me to talk about this, since I’m not connected with this area. Sorry for my English.
I've been using F360 for about 6 years at this point, and I frankly had no idea that you could even do this kind of analysis as I've never had a need to do it (although I think I'll start incorporating it where desired now :P) Thank you for the educational video!
Have you considered offering a premium courses in Fusion? Something that is project based and organized as a course/workshop. I would buy it in a jiffy.
So you think you are getting pretty good at Fusion and then watch this. The sinking feeling of realizing you are a beginner. Good video. I think I'll go back to crayons and sheets of A4 paper now. I managed to retain about 5% and would need to watch this another 15-20 times.
Great video! I like your method of defining the point spacing with constraints. Maybe worth mentioning that I believe Fusion 360 uses a maximum of degree 5 splines, which would affect the point spacing. For the airpods form, I think a smoother round can be achieved by not specifying the curve on the flat top surface, sweeping the profile around the path, then patching and trimming the top surface after the blend. If there is bunching then the profile curve is too big or the corner is too tight.
I used a lot of these techniques in Autodesk Alias Studio. Glad to see that many of those techniques translate to Fusion in a more rudimentary way (less functions for surface continuity control, etc.). Unfortunately for me, most of my modeling needs are organic shapes with complex curve surface patterns/textures. I'm trying to avoid using Alias as it's over $1000 a month (I know... ridiculous). Fusion gets me 90% of where I need to be, but I'm trying to avoid being financially drug into Alias again. I really wish either Fusion included better surfacing controls, or they actually make Alias affordable on subscription for consultants.
Thank you for this excellent sharing, I learned a lot So I reproduced the airpod without difficulty except for the details because I don't have the plan What is the process of constructing a spline with an angle other greater or less than 90° and continuity with lines of different lengths in x and y?
I would kill for a CAD Designer at my billion dollar company to have a fraction of the knowledge you have dropped in this video! Do you have any resources that you've helped to build your knowledge around surfacing?
Why did you take the dimensions that you have taken and how did you estimate them ? I am trying to make something similar but I am finding it really tough to figure out the dimensions of the offset and the inside curvature radius
Could you make an updated version of this tutorial? That would be amazing. The constraints do not work anymore like they did in the video. To be specific, The section at 14:00
May not be a video, but maybe this helps... Most thicken errors are because the offset surface is self-intersecting, sometimes these are hard to see without evaluating the surface, so this might be happening on a micro scale. If there are imperfections or tight curvature on the surface you are trying to thicken, those imperfections are amplified by the amount of offset, causing self-intersection. The biggest culprits for this are if you are trying to thicken an already offset surface, or more likely, a non-planar patch where the edges might have curvature hotspots because the algorithm is trying a bit too hard to match curvature with the connecting surface. Lofts are more forgiving to thicken than a non-planar patch, sweeps and revolves are more forgiving than lofts. If you are using t-splines, they run into similar issues as the patches. A workaround for this is instead of using thicken, try offsetting the primary surfaces and re-construct the connecting surfaces with new lofts/patches/etc. Takes longer, but more reliable. Solidworks has the same issue, it's the nature of parametric modelers that run checks on surfaces. Hope that helps.
saw how well it worked on your RC body and thought why wouldn't it work on mine, I guess I just need to learn how f360 calculates, I'll do more trial and errors to see how much it tolerates, thanks for you tips
