A quick way to convert is to take a screen capture (Snipe Tool for windows) and (command shift 4 on Mac) the PDF Image (save as JPEG), then import the JPEG into REVIT but do not explode. I usually pin it just to keep it from shifting, then, scale the jpeg image with a wall or model lines at the drawing scale. I turn on the imported layer (VG check or uncheck the imported file) when I need it, and when I don't. I find that this old fashioned scaling way is the fastest, and when scaling, you can zoom in as much as possible to the reference points to increase accuracy.
