Tangency vs Curvature Continuity when Creating Fillets and Lofts

[@GeorgeGraves]

Wow - you have some great videos - more people should see this stuff - I'll try to share them.

[@LearnEverythingAboutDesign]

Thank you!! Much appreciated.

[@robertojofre15]

Great video , can’t thank you enough, im definitely going to stay posted for further videos

[@LearnEverythingAboutDesign]

Thanks! This topic is tough and everytime I mess with it I realize there is so much I don't know.

Looking forward to more. I want to know how I can get the cleanest transitions. It seems like the tools in F360 just don't completely cut it for this kind of work.

[@LearnEverythingAboutDesign]

Hi Keveira, Sadly the tools in F360 surfacing, in my opinion, are lacking a little. The cleanest transition is generally done with forms tools. Maybe I could do a follow up video using those tools. Essentially if you have surfaces you can use them to drive a form surface using the Match tool and set the continuity to tangent or smooth.

great video friend

Thank you

This is great!!

[@usamahibrahim2201]

In terms of production, what should be considered most? For example, how should we choose between a tangent or a curvature when designing a mold from it? great vid enjoyed it

[@LearnEverythingAboutDesign]

Usamah, the choice between Tangent and Curvature is really based on what you are designing. There are implications though. One good example of this is just extrude a box, then add a fillet to one corner. A normal fillet is a tangent based arc. The fillet has a tangent relation to both faces. You can change the fillet to be curvature based. What you will see is the corner gets a little tighter(all things being equal). The choice depends on what you have to work with. If my surrounding faces are flat, or only have curvature in one direction, tangency is usually what i use as it makes little to no difference in the end shape. If you are trying to patch a complex shape that has curvature in multiple directions often times the Curvature is needed. For production the main considerations are going to be the minimum radius of whatever curve you are making because you don't want to design a big part that needs a very small tool to cut the geometry. So globally try to remember the size of tool but that is true for tangency or curvature.

thank you! looking forward for surface mastery video

[@LearnEverythingAboutDesign]

Thanks Zuvince. I have been planning it out but it has been tricky. The surface tools aren't behaving like I would expect them too so I have been waiting for software updates before doing that. I do hope to add more surfacing content. The most recent video is mostly surfacing tools.

@@LearnEverythingAboutDesign Thanks! I have the same problems with surface tool in Fusion, complex surfaces are messy and unpredictable. Could you recommend software that is more pristine in surface modelling and modelling complex surfaces for product design? Rhino maybe?

[@LearnEverythingAboutDesign]

@@zuvince Before my Fusion days I was a Solidworks User. The surfacing tools in there are a step above, but at a cost of course. Inventor does have decent surfacing but the process for making projected curves has always been a pain for me. I have hopes that the surface tools in Fusion will get better in the next year or two, but only hopes. I have been using Fusion since 2015. I have heard good things about Rhino but I haven't had the chance to really play with it much. Maybe I will soon so sadly my impression is only 2nd hand on that. The 2 things I can say are that Fusion Forms are pretty good if you know how to make them behave, and 2 that I have given all my feedback to Autodesk regarding the surface tools shortcomings. I enjoy working with Autodesk because they are receptive to feedback. Even when I worked at a Solidworks reseller I never felt like I had the same connection to the people that make the decisions. I have Rhino on my list of programs to play with but of the tools that I have played with I would say that for ease of Use Solidworks was the best. For toolset for surfacing it would be Alias and NX. Both are very expensive tools! In Solidworks I had designed several cars/motorcycles/concept vehicles as well as parts that were injection molded, machined and fabricated in other ways and never felt that surface quality was an issue. Hope that helps! and if I get to testing Rhino I will let you know. Feel free to email me [e-mail] as well.

@@LearnEverythingAboutDesign fingers crossed
