segLen should work with sketch segments.

[adamchalmers]

Currently segLen(extrude001.sketch.tags.line1) works, but I also think segLen(sketch001.line1) should work too. Currently the latter errors:

  × argument: The input argument of `segLen` requires a value with type
  │ `TaggedEdge`, but found a segment (with type `Segment`).
    ╭─[17:12]
 16 │ // Measure its side lengths
 17 │ side1Len = segLen(sketch001.line1)
    ·            ───────────┬───────────┬
    ·                       │           ╰── tests/seglen_with_segments/input.kcl
    ·                       ╰── tests/seglen_with_segments/input.kcl
 18 │ side2Len = segLen(sketch001.line2)
    ╰────
  ╰─▶ KCL Argument error

Once it works, go back to the KCL book chapter on measuring segments (under fillets.md) and update the examples to use this simpler form.

Footnotes

1. 152 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (c749dcd) during the generation of this report, so 67c1c35 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
