How EPR Identifies Sheet Numbers
During the document render process, optical character recognition (OCR) runs to try to identify sheet numbers automatically. While OCR technology has limits, three main factors affect whether EPR can identify a sheet number properly:
- Location and Page Rotation
- Font Style
- Sheet Number Pattern
Location and Page Rotation
To reduce the potential for errors, EPR focuses on the lower right corner of the incoming page to try to identify the sheet number (as highlighted in red below):
...
Proper linking of page versions using Sheet Numbers allows EPR to automatically migrate markups (both comments, sketches, etc.) to the latest version of a document page, even when resubmitted plans consists of only new and changed pages instead of the full set.
Document Page Linking
Partial Submittal OFF (Default) | Partial Submittal ON | ||
With Partial Submittal OFF, sheet numbers are NOT required to link pages. Instead, EPR will link pages by the page position within the document. Limitation: Subsequent submittal versions CANNOT have fewer pages than the previous submittal version. | With Partial Submittal ON, sheet numbers ARE REQUIRED and EPR will link pages by the sheet numbers provided. This means subsequent submittal versions CAN have fewer pages than previous version. |

| Comments are moved from version to version by the sheet numbers provided. In the example on the left, Submittal 1 has S2 as page 2 but then S2 is the first page in Submittal 2. This is okay because we are able to identify each page by their sheet number, so comments and other markups can be moved to the matching page. |
