How can I improve the accuracy of OCR on my drawings?

When you upload drawings to a project, Procore can automatically pre-populate the following fields to help expedite the upload and review process.

  • Drawing Number
  • Drawing Discipline
  • Drawing Title

Procore leverages Optical Character Recognition (OCR) technology to intelligently discover and pre-fill these fields with the correct value based upon the title block (for the title), the number on the drawing (for the number), and that drawing number's letter prefix (for the discipline). See Which fields can Procore automatically populate when uploading drawings?

In order to improve the accuracy of this character recognition technology, we recommend you configure your drawings with the following format.

Drawing Format
  • Request vector PDFs from the design team as opposed to a mixture of vector and non-vector (raster). See What is the difference between raster and vector content in PDFs?
  • Drawings must be in PDF format.
  • Rotate the drawings properly before uploading, they should be oriented as landscape.
  • Important notes for AutoCAD users
    • The following are the main things to look for in order to create selectable and searchable text in a PDF from AutoCAD:
      • Use a TrueType font.
      • Do not alter the text from the original font, such as changing width (must be 1.0) or other style options.
      • Make sure the Z coordinate value of the text is zero
    • AutoCAD users should turn off the "text as comments" feature before publishing a PDF for use in Procore. Exporting your drawings as a PDF with this feature enabled may impact Procore Drawings tool OCR.

  • Put the drawing number in the bottom right with the title nearby.
Drawing Block Text


  • Format
    • Use a drawing title label and drawing number label (e.g. Sheet Title: and "Sheet Number)
      • OCR is more likely to find the title and number if both are close to the respective label.
    • Drawing number and title are bigger than other text in the title block.
    • Use a simple Sans-Serif font like Arial (or any UTF8 font).
    • Text is best horizontal. The title may be vertical.
    • Procore recommends that you embed fonts in your PDF files when saving them so that they display as expected when opened in other programs
  • Title
    • Try to keep the title to one line when possible.
    • Titles should be less than 255 characters.
    • Use English words in the title. OCR recognizes words found in the English dictionary only.
  • Number
    • Put the drawing number in the bottom right with the title nearby.
    • Do not use English words in the Number. (e.g. Drawing Number One)
