Sharing a free parametric grid script for Illustrator — Swiss Grid Explorer v1.1

Hi everyone! Wanted to share a free, open source script I built for Illustrator. Posting here in case it's useful to anyone working with grid systems.

Swiss Grid Explorer generates vector rectangles on a locked Swiss Grid layer plus native magnetic guides on a locked Guides layer. Parametric dialog with live canvas preview, zoom controls, and import/export JSON settings.

Six presets based on historical references:
— Brockmann 8×8, Gerstner 6×6, Vignelli 3×4, Tschichold 2×3, Digital 12, Slides 4×3

Each preset scales proportionally to any document size. Bilingual interface: English / Spanish. Compatible with Illustrator CC and later, CMYK and RGB.

Install: copy the .jsx to your Scripts folder, restart Illustrator, then File → Scripts → swiss_grid_explorer.

Has anyone built something similar or have suggestions for improving the preset system?
