Hi Is there a way to put concave and convex curves into separate lists? I wish to join the convex curves in the picture and fillet them, and then extend all the curves outwards, like in the second picture. [Convex1] [Convex2] List Convex Curves.gh (12.7 KB)

Instead of fixing the problem, I created a RotateXYZ cluster in the hot pink group to rotate geometry in all three primary planes at the same time; XY, XZ and YZ [Convex Curves_2025Apr24b] Convex Curves_2025Apr24b.gh (32.5 KB)

Thank you so much both! only had the opportunity to look at it now, this is perfect! I like the List convex curves b version version a bit better because it is easier to extend the lines. The purpose is to use a CNC drag knife that cannot cut sharp corners. Thank you

[image] Pegelatrin: I like the List convex curves b version version a bit better because it is easier to extend the lines. I don’t care which version you like better but List Convex Curves b.gh has no extended lines at all? My version (Convex Curves_2025Apr12a.gh) has a Extend Curve componen…

Oh sorry, I wasn’t comparing your code with Leopolds, I was comparing Leopolds B version with the C version. Yours work perfectly as well!

Hi Just wondering if there is a way to solve the problems that seems to appear on some shapes using your code. Some of the shapes come out right like on the upper left, but others fillet the wrong curves or the entire shape like the bottom one. The reason for this is because I am trying to attach …

[image] Pegelatrin: Just wondering if there is a way to solve the problems that seems to appear on some shapes using your code. Whose code? The GH you posted looks like it starts with some of mine (not sure which version?) with a different set of test curves, to which you have added two chun…

Ok, this is your code unmodified. I just added some extra code to show what I was using it for. But the problem lies in the previous code that some shapes, will have some errors, and I am not certain as to why. It worked on the example that I provided, but when I applied it to the shapes I intended…

Check to see if this helps: Convex Curves Loop.gh (28.3 KB) 'Not saying I got it right. However, if we’re ‘strict’ about what your topic title implies, then @martinsiegrist gave you the answer long ago. [image] Also, I wouldn’t trust Fillet@parameter component. It’s weird. And, you can only fil…

Thank you! This seems to work great!
Ok, I will check if the fillet can be replaced with something else
