What's the difference between a raster PDF and a vector PDF?
A raster PDF is a grid of pixels (a scanned or rendered image); takeoff happens by clicking on pixels. A vector PDF preserves the CAD layers, entities, and points it was created from; you can isolate layers, snap to entity points, or click an entire polyline at once. BidScreen XL labels the active drawing as Raster, PDF, PDF Vector, or CAD in the top right corner of the drawing window.
