HGL to CGM Conversion: FAQ

What are HGL files?

HGL files are the vintage blueprints of the digital world - they're the instructions that old plotter machines used to follow to draw technical designs with actual pens. Developed by HP for their plotters, these files tell the machine where to move, when to lift the pen, and what lines to draw. While they were big in the 80s and 90s for engineering drawings, today you'll mostly encounter them when digging up old project files or working with specialized equipment. The good news is you can easily convert them to modern formats using current software, which is handy whether you're preserving old designs or updating them for new uses. They're like the cassette tapes of the design world - outdated, but still containing valuable content you might want to preserve.
