Thanks for the video! At the end of the video with the solid body interesting it did not shell the fillet? But it did it with the surface thickenning

[@lukaszb1282]

10mm fillet - 10mm shell and you get edges without fillets 🙂

[@Fusion360School]

Thank you for pointing this out. I went back to do this again and realised that I had performed the thickening towards the top. This meant that the top fillet became 20 mm after thickening. For the shell, I had performed it on the inside, which meant that the 'thickening' was reversed. Since the shell thickness is the same size as the fillet, this resulted in a sharp edge at the bottom. I should have used a larger fillet. For a true comparison, I should have thickened downwards. Thickening downwards would also produce a non-flat bottom face. So this should not take away the main message of this video. Sorry for the confusion caused.

@@Fusion360School That's interesting. I assumed the choice was intentional and Fusion would moan if the fillet was fine earlier in the sequence

Truly underrated modelling software and even more underrated channel. I really appreciate the time and work you put into these videos :) I was studying mechanical engineering and had a whole semester was spent "learning" 3d modelling and simulating. Can confirm, the degree of professionalism shown in this video tops those 5 moths easily. Again, thanks for the effort you put into these videos, you mysteriously beautiful man!

[@leeackerson2579]

Wow, like a semester of CAD design in a few moments, thanks much, you are a friggin genius.

[@stefanguiton]

Excellent! Shell is underrated

[@alejandroperez5368]

No, it's not

[@373346507]

What if you thicken to inside and then cut the extra? This way the measurements will be more similar to the shell way?

[@Fusion360School]

Yes, you can definitely perform an extruded cut the make the bottom face flat.

[@Spartacusse]

My thoughts exactly.

[@spydergs07]

@@Fusion360School That's how I've been making most of my flat bottoms, but I like this way a bit better. Going to try this method out.

[@smorris12]

Excellent video as always (here's some extra words to keep the algorithm happy. I wonder if there's a perfect comment length it would like to see?)

[@lukaszb1282]

After the firts workflow it's possible to replace face from top plane? IT should work 🙂 But of course, very useful video.

[@Fusion360School]

Yes, replace face should work. I often try to avoid using replace face as it is kind of a hacky way to do things:)

[@bobreichel]

Don't know if you can help, but I'm tring to put a kind of S pattern hole in my model and want it to skew in opposite directions on each half. Sort of like a plane prop. Can't find any videos even remotely like this.

[@alejandroperez5368]

You didn't even need to use the surface modeling space... I rarely use it

[@robpet198]

It's true, you do rarely need it. But the flexibility it offers is truly astonoshing, especially if you consider how well Fusion 360 tackles some of the features / commands. Great to know there are other ways, in case you need it.

[@mkay9565]

I agree. This particular case didn’t need surface modeling. It could have been easier with solid modeling.

The purpose of this video was to demonstrate the difference between thicken and shell, not to show how to create a particular object.
