The one-piece G3 gave me no troubles, and yes, not too troublesome to set up with formulas. The ones with the constant radius in the middle gave me over/under defined problems (SW2023). Thanks for your investigation. Your Rhino vid on 'the finger' is next level!
Hi Schalk, long time no talk! Was it the transition splines that were giving you over/under defined issues? I find sometimes I have to define the continuity constraint first, then define the CV placement, or vice versa. Unsure what makes it work one way but not the other. Also, having the CV spacing approximately equal first can help.
Hey Andrew, the ones with the constant radius gave me troubles in SW 2023... would not define fully but also throws out over-defined errors when I tried. Devised my own numbers from the one piece G3 you did and got no troubles (so, my fav.). Thanks for the investigating. Your Rhino vid on 'the finger' is indeed next level.
Thanks for this Andrew! 3 Piece G3 with relief looks best to me from curvature comb point of view. Although rest look great as well. Three-piece g3 without setback seems a no go.
Love this exploration! Seeing as you went with the three-piece G3 with relief on the M1 pt. 2 video, I'm curious if there's any functional difference between adding the 1.5mm diameter relief circles vs. changing the values in the initial control sketch. I measured out the arc length and g3 transition distance after adding the relief and found: Arc section radius: 10mm (unchanged) Arc section offset multiplier: 1.025 (unchanged) Arc length: 45° -> 36.4° G3 transition setback multiplier: 1.416 -> 1.491 If you plug those values back into the original control sketch, the three-piece G3 no relief ends up having the same curvature combs. If anything, making the change to the setback multiplier would make this more applicable to any size blend - 1.5mm of relief wouldn't go as far on 200mm corner. This is pretty close to a set of nice round numbers (for example, Arc length: 35°, G3 transition setback multiplier: 1.5) that I can use as a rule of thumb when creating arc-approximating G3 blends, which is awesome!
Wow, good investigation! I think I was running out of energy for the exploration, so did not look at creating a ratio for the relief circles. Definitely sounds good to have a nice round set of numbers to drive the corner with!

This is all such useful information Andrew, thank you for uploading!
Hi Duncan, all good, thanks for watching!
Nice! Thanks for taking a look at the squircle!
No problem at all!

Hi Tony. Yes, that still has a good section of arc left even with the relief.

thank you always jackson bro!!!
as i saw in last video, 1k in first day, ppl love curve!
can i download it?
Hi, try the link now. It'd gone dead for some reason.
nice!!!
