Not sure what the original issues was, but I found that using a non zero thickness trailing edge on my wings (e.g., 0.01mm) solved all my fillet issues with F360, as it segments the fillet operation to each size without singularities messing things up (hope this makes sense).
HEy Tony, just messing around with this technique, but the intersect points disappear after OK. (I have points selected) any reason why they are not visible?
Have you checked your sketch folder to see if they are turned on? If not, go into your sketch folder and turn them back on if they are off. Your sketch can turn off after you hit OK.
@@rooibaard123-w8m Hi, from a mathematical point of view it means that every curve drawn on the surfaces it's continuous. From a layman point of view it means that the transition between a surface and another it's enough "smooth", so when you see it in real life or in the CAD without the edges shown it's somehow difficult to discern where a surface ends and another start. As you can see in the video there is clearly a "bump" where the wing and fillets meets. This is not good from an aesthetic point of view and an aerodynamic point of view since the flow does not like discontinuous changes in slope and can separate, create an unwanted acoustic emission. In reality, i mean in the real aerospace and automotive industry G1 continuity is not enough, G2 is necessary, that is: continuity in the curvature field...and also consistent curvature in the single surfaces. Something that is absolutely not achievable with "the loft workflow" that is shown very frequently on YT tutorial where sections are drawn and then lofted to create the fuselage. Failure to achieve G2 continuity and consistent curvature means that the aircraft panels would not even be manufacturable and aerodynamic efficiency would have a cut. Fusion 360 do not have the instruments to achieve what i said...a procedure that it's called "Class A Surfacing". A large number of common products that you see in the world are designed in low-level software like Fusion-360, Rhino, Solidworks, etc...but before production and CAE, CAM analysis are re-drawn by Class-A surfacer using high-end software like Dassault ICEM, Dassault CATIA, Autodesk Alias, Siemens NX. That said G1 continuity is achievable with Fusion-360 but it needs a little experience and patience. Obviously it's NOT a critics of the author of this video that is doing a GREAT work for showing new CAD user a place to start designing your own planes!!!!! If you want more in depth info about G0-G1-G2-G3 continuity search on you tube "G1 G2 continuity" or "Class A surfacing"
@@rooibaard123-w8mbasically, it's about the connection between the 2 surfaces. G0 means that they are connected, G1 means that they have tangency (smooth transition rather than an abrupt one). You can see some sort of a seam in the model in the tutorial where the loft starts. Had there been G1 continuity rather than G0 this wouldn't have been the case. Hope this helps. I am just a beginner with no math or modelling background though, so take everything I said with a grain of salt 😅.

The best 👌
Right on! This is great, thank you.
I think this is the best tip yet!
Can you design a blended wing body?

there is not an "easier" way but a more correct one, those two pieces do not even have G1 continuity
Would you mind to explain what G1 continuity is? thanks.
