Everything you need to ship correct drawings

Custom guideline sets

Define unlimited inspection rules manually, or upload a checking-guidelines document and let AI extract them automatically.

Multimodal AI inspection

Upload a PDF or image of your drawing — AI reads the geometry, dimensions, notes, and title block in one pass.

ASME Y14.5-2018 GD&T

Every inspection also checks datum frames, feature control frames, MMC/LMC, form/orientation/position/profile, and Rule #1.

Tolerance stack-up analysis

1-D stack-up with nominal sums, worst-case bounds, RSS tolerance, and per-chain OK / MARGINAL / FAIL status.

Errors highlighted on the drawing

Failures are overlaid directly on your drawing so you can see exactly where each issue is.

Structured pass/fail reports

Per-rule verdicts, overall score, and a clear OK / NOT OK decision driven by your critical rules.

Private by design

Row-level security keeps your drawings and reports isolated to your account. One user's data is never visible to another.

Discount codes for new users

Admins can generate codes from 10% to 100% off, applied right at signup and checkout.

/ About

Built for engineering teams who care about drawing quality

Drawing Checker is operated by Choppers & Roadsters. We help mechanical and manufacturing engineering teams catch drawing errors before they reach the shop floor — by codifying your internal checking guidelines and running them on every drawing, automatically.

Every inspection combines your custom rules with the ASME Y14.5-2018 GD&T standard and a 1-D tolerance stack-up analysis. You get a clear OK / NOT OK verdict, per-rule pass/fail evidence, and failures pinned directly on the drawing.
