The method I’m going to tell about is a part of invented in late USSR EMKO system. It was developed specifically to use with computers so it doesn’t have “use a french curve” instructions and things l…

I also LOVE this method :slight_smile: Here are my test files: Close Fitting Bodice Block3.val (21.1 KB) Women 12 measurements.vit (1.1 KB) There’s absolutely no way the curves can go out of whack…

@KeithFromCanada Haha thank you! Can I tell everyone I’m a certified witch now? @Grace you don’t need to draw every circle separately, there is a tool “point of intersection circles”, check it out! Y…

Check THIS out! (The graphics are interactive.)

Looks interesting! I think I may later try to re-make curves as arcs using this logic on my bra base pattern (those curves where the cup is to be sewn in the main part are a pain) Now I’m reading int…

[Bild] KeithFromCanada: Check THIS out! (The graphics are interactive.) Haha! how cool would it be if we could have the same interactive curve tools in Valentina :slight_smile:

@Krolich , I checked your system, and there is a (soluble, I think) issue with it. For curves to join smoothly, they have to add up to 180 degrees where they meet. This means that both centers must l…

…and I’ve solved it after a good power nap with a bit of trig. I’ll explain the diagram below. Basically, any two points on a circle (A & B) plus the center (C) form an isosceles triangle, where the…

good find. i used to know all that when i aced geometry about a million years ago

If you want arcs to line up at 180 АND angle in point H1 to be 90 (which is the usual requirement for patterns) there is just no such point that might be a center of that circle. Somewhere here we mus…
