Redline Checker
Beta — for testingVerify every markup was actioned
Upload the original drawing, the marked-up redline and the revised drawing. VerifyCAD reads each markup instruction and confirms whether it was actioned, missed, or needs a human eye.
VerifyCAD reads your markup and checks each change against your revised drawing. It flags anything it can’t confirm for you to review — it assists your review, it doesn’t replace it.
e.g. “a red X on a line means add a valve there” — helps us interpret your markup.
Got a DWG? How to export a DXF or PDF
VerifyCAD reads DXF, PDF and image files. If your drawing is a DWG, here’s how to export a DXF (or simply plot to PDF):
- AutoCAD: type SAVEAS, choose ‘AutoCAD DXF’ as the file type, and save.
- Other CAD software (DraftSight, BricsCAD, etc.): use File → Save As and choose DXF.
- No CAD software? The free ODA File Converter (opendesign.com) converts DWG to DXF on your computer.
Your files stay on your machine — you’re just saving a DXF copy to upload.
Add all three drawings to run the check.
