![]() I have tried every method out there to georeference the CAD drawing, including: There are features listed in the properties and visible in the data frame when loaded into ArcMap.The Coordinate System is unknown and the source can't provide the information.add the raster image (for reference, mostly).My understanding of what needs to be done is as follows: I have raster imagery of the area of interest, point data for the households, and a CAD drawing of the proposed pipeline and buffer areas. And not just because we're Luddites.I am working on a project to identify households within certain buffer areas of a proposed water pipeline. We just want to retain the option of plotting to raster. ![]() Vector PDFs are great and have their place. My computer is 4 years old, not new but not ancient. It is very slow to regenerate as I pan around. It has translucent solid colored hatches on top of the aerial photo. It has an aerial photo background as raster, elevation contours and proposed improvements as vectors. Right now I'm looking at a 22x34 PDF from a client made with Civil 3D 2018. Raster is just simpler and more reliable.Īnother reason for Raster PDFs: Vector PDFs can be slow to use on-screen. Sometimes complex mixed vector PDFs won't print at all. Not all printers/plotters will render a complex PDF with large amounts of mixed vector and raster content the same, especially when you add things like shading/opacity of rasters, and scaling into the mix. Another major reason is plotting fidelity. "Locking down" a PDF is not the only reason to print to raster. It seems to me the benefits of vector PDFs far outweigh the perceived protection/reduction of liability of raster PDFs. ![]() Vector PDFs are typically smaller than a raster equivalent, and have the additional benefit of producing a higher quality plot. I understand the modern-day apprehensions of vector PDFs, but I firmly believe they are the best archival format we have available today. Before xerographic copiers, blueprints were the only way to reproduce large format drawings. Being a light-sensitive process, blueprints required a transparent vellum or Mylar original to create. Since xerographic copiers could copy anything, many feared the repercussions of theft as they displaced blueprint machines that had some level of copy protection built in. To me the recent discussion about rasterizing PDFs as a way of locking them down is no different than the discussion about large format xerographic copiers when they were first released. Have you encountered any issues with your drawings being stolen in that time? ![]() That functionality has existed for no less than 5-8 years. While the convert PDF to DWG functionality was just introduced in AutoCAD 2017, it's always been possible to convert vector PDFs to an AutoCAD readable format. Inkscape, the open source vector graphics application, can export to DXF, whereas Adobe Illustrator can export straight to a DWG. I'm not trying to be "that guy", but I might I ask with the most objective intentions why the need to lock down your PDFs? During similar discussions with clients, I've found the question typically stems from a perceived liability about people nefariously reproducing their drawings. ![]()
