Expanded text contains internal edges

[abejfehr]

I'm looking to expand some text and inset it on a shape. I've noticed that with a few characters, particularly numbers, it creates some overlapping sections, even if I union them.

This is some sample code:

  const labelSegments = vectorText({
    input: "123456",
    height: 3.5,
  });

  const labelPaths = labelSegments.map((s) => segmentToPath(s));

  const labelOutline = union(
    ...expand({ delta: 0.6, corners: "round" }, labelPaths)
  );

And here is what labelOutline looks like:

I don't see any other tools that could be used to create 1 outline per character, but I may have missed something. How can I avoid those internal lines that appear on the 1, 3, 5 and 6?

This is the same problem as #782 , and cannot be solved easily.

however, there are other ways to assemble 2D outlines from the set of points (letters). Please see the example on text.

@abejfehr There is also a little module that can be added to JSCAD projects, which can produce outlines from TTF fonts. You might be able to use this instead, after making some changes.

@abejfehr keep an eye on V3, a new 2d boolean alg is being added (martinez) #1177 and it will likely be much better at handling things like that.
