Fusion 360 Gasket (Learn from this Beginner Exercise) 

I would have done this soOo much differently I would have started off with a center point rectangle on the origin Then I would’ve tossed down some horizontal and vertical midpoint construction lines Then I would have picked just one of the four subsections to work within. Then I would’ve tossed in some dimensions, circles and arcs, etc Finally, mirror tool using the earlier horizontal and vertical construction lines to complete the missing 3 sections. This is just how I would do something with this much symmetry. Of course the whole reason I started watching your channel years ago it’s because you geared your content towards new users.

Brilliant, I'm a newbie to CAD and this tutorial is crammed with really helpful tips, thank you!

very professional thanks for the tutorial :D

Thanks Tyler. I have adopted the constraint first technique and it has really helped with regard to making changes. Much appreciated as always.

Great example of constraints!

Excellently explained. So helpful. Thanks you

Interesting way to go about this. Regardless, I always learn something new every time. Thanks for the content!

IMO, it's by far the best tip to look for the lock for making sure everything is defined. Sadly, everything can look black, but you can have points that are not defined, which will prevent the sketch from being fully defined. It's a weird problem, not sure if maybe keeping lines that have points on them undefined still blue would work, but it'd be nice if something was done... Of course then you end up needing to use the command line and using the sketch.showunderconstrained command, which helps quite a bit, but can still be a bit tough to find things on a busy/complex sketch.

amazing as usual thank you

Thanks Tyler, another great video. You have really helped me come along in Fusion. Also I have really enjoyed your Jump Start course. Also, why did you draw the two construction lines instead of just one?

Can anyone explain why a regular circumscribed hexagon, pointed down to the origin and with a defined side, drawn using standard Fusion 360 tools, does not show up as a fully defined sketch? I don't understand the logic of sketching at all :(

This doesn't work for me, the top and bottom arcs are snapping to the construction lines and when I put the radius of twenty for the middle arc, it balloons out of proportion with a giant circle and zig zag lines..
