I built a free offline web app for AutoCAD drafters — 37 reference tools that work on your phone without an internet connection
After 20+ years in AutoCAD and several years doing utility engineering drafting, I got tired of answering the same questions from new drafters and field crews — scale factors, LTSCALE, metric to imperial conversion, annotative text setup, layer standards. Always the same stuff.
So I built UtilityDrafter.com. It's a progressive web app — meaning you add it to your home screen like an app, and it works completely offline. No app store, no login, free.
What's in it:
- Scale calculator (paper space, model space, annotation scale)
- Metric ↔ imperial unit converter with the full math
- Annotative text and DIMSCALE guide
- Layer standards, linetype guide, hatch calculator
- Viewport and paper space setup
- LISP scripts and snippets you can drop straight into AutoCAD 2024
- Drawing health audit checklist
- Utility industry tools (conductor sag, conduit fill, wire ampacity, transformer sizing)
- SDGE overhead and underground construction standard readers
Built it for myself first, figured other drafters might find it useful.
Would love feedback — especially if something's wrong or missing. What do you constantly look up that isn't there?
