DatumPilot
A GD&T interpretation tool that parses feature control frames and explains tolerance zones in plain language. Built by Ingenivue Engineering Services Inc.
Why we built it
We do a lot of GD&T work—tolerance analysis, drawing review, stack-ups. We kept running into the same problem: interpreting complex feature control frames takes time, and mistakes are easy to make when you're working fast.
DatumPilot started as an internal tool to speed up our own work. It parses the FCF, checks the syntax, and explains what the tolerance actually means. We found it useful enough that we made it available to other engineers.
What it does
- Parses feature control frames and identifies tolerance types
- Explains tolerance zones in plain language
- Identifies datum reference frames and modifier effects
- Validates syntax against ASME Y14.5 rules
- Generates interpretation summaries for design review
Position tolerance of ⌀0.25mm at MMC, referenced to datum A (primary), datum B at MMC (secondary), and datum C (tertiary).
