Extracting Elevation Data from PDF files (Contours, Spot Levels etc...)

That’s a really interesting process and definitely a useful one for saving time during takeoff planning. You’re right—PDFs aren’t meant to hold technical metadata, so extracting accurate elevation data can be tricky. Still, with the right tools and workflow, even partial data extraction can be a big help.

If anyone is working with complex PDFs regularly, software like Corel PDF Fusion can be useful for organizing and viewing technical documents more clearly before extracting content into CAD. Looking forward to seeing what specific items you've identified for extraction.
