Open-source line-weight tool for architects (Make2D) - Day 1, WIP

I keep hitting the same workflow tax: Rhino Make2D gives clean linework, but it comes out flat and uniform, so I re-weight cut / profile / hidden by hand after every revision. I started a small, free, open-source tool to do it deterministically.

What it does

  • Takes a Make2D export (.ai / PDF), buckets strokes by color, and assigns architectural line weights (cut / profile / hidden) from a preset - same result every run.
  • Adds solid-black poché on cut layers.

Where it’s at (honest - early WIP, Day 1 of building this in public)

  • Works on PDF-based .ai / PDF exports.
  • Known limit I just found dogfooding: legacy PostScript .ai exports aren’t read yet - re-save them “PDF Compatible” in Illustrator (File → Save As) first. A clearer error for that case is my next fix.
  • Not packaged on Food4Rhino yet; I’ll publish there once it’s past the rough edges.

Free & open-source: GitHub - zohartito/arch-line-weights: Apply architectural line-weight hierarchy to color-coded vector drawings (Rhino-exported .ai/.pdf) in seconds, without opening Illustrator. · GitHub

If you produce drawing sets in Rhino (+ Illustrator), I’d really value feedback: which export paths and conventions should it handle, and what breaks on your files? I’ll add real cases to the test set.
