ericepv Posted May 11 Share Posted May 11 I am looking for away to make a CAD file from a PDF for the purpose of creating elevation data that can be brought into Chief. My customer has provided me with a detailed topo map of the property but has not been able to obtain the original CAD file. Link to comment Share on other sites More sharing options...
Chopsaw Posted May 11 Share Posted May 11 You could convert your PDF to a .dwg file but that won't give you elevation data. You should be able to get some lines or points that you could manually convert to elevation data perhaps. Link to comment Share on other sites More sharing options...
JiAngelo Posted May 12 Share Posted May 12 Most convert to raster or the vector data is inaccurate. Also you would need to resize the result to match real world dimensions. For small sites it is easier to import the pdf, scale it to real world dimensions, lock the layer and draw terrain, lot lines and elevations over it. For larger sites, our auditor has dwg/dxf files we can download with terrain elevation data using Arcgis. Your New York area uses this system as well.

GeneDavis Posted May 13 Share Posted May 13 This will clarify your mind, if I may quote from the lyrics to the old old blue song, "Trouble in Mind." Watch how easy it is to draw what you need over the .pdf and get to a terrain, and then watch the magic of creating an "as built" terrain, then the cut and fill to create what is needed. It has been linked before in terrain threads. Link to comment Share on other sites More sharing options...
