PDF mark-up to DWG drawing revisions

Pair the PDF mark-up with the matching native CAD file. This service updates your editable drawing from marked changes; a PDF by itself may need a separately scoped redraw.

A PDF is not the CAD model

PDFs may contain vector lines or only a scanned image. Text, scale, layers and external references cannot always be reconstructed reliably from the PDF alone.

Match the source and mark-up

Supply the same drawing number, title and revision wherever possible. If your source differs from the marked-up issue, explain the difference before production.

How the drawing moves forward

  1. Upload the matching CAD, marked-up PDF and project references.
  2. Review the estimate and accept the confirmed scope.
  3. Track drafting and respond to logged queries online.
  4. Review the checked proof, approve it and pay before final release.

Questions before you upload

Can you work from a scanned sheet?

A legible scan can support a manually reviewed scope. Poor resolution, missing scale or obscured notes may require clarification or a new source.
