The next time a client emails you a screenshot of a Google Maps pin, you won't just see a picture. You'll see a dataset waiting to be georeferenced, scaled, and transformed into precision CAD geometry. Word count: ~1,400 Tools required: AutoCAD (any version 2015+), Google Maps (browser), Google Earth Pro (recommended).
Google Maps images are raster files—pixels without inherent distance. Unlike a CAD drawing, they don't "know" that one inch equals 100 feet. Scaling a map image correctly is not just a convenience; it is the foundation of site planning, solar analysis, traffic flow studies, and preliminary grading designs. how to scale google map in autocad
(defun C:MapScale ( / ) (setq img (entsel "\nSelect image: ")) (setq p1 (getpoint "\nPick first reference point on image: ")) (setq p2 (getpoint "\nPick second reference point on image: ")) (setq realdist (getreal "\nEnter real-world distance: ")) (command "_.SCALE" img "" p1 "_R" p1 p2 realdist) (princ) ) This reduces the seven-step process to three clicks and one number. Scaling a Google Map is always an approximation. For permit sets, grading plans, or legal descriptions, you must trace the map with CAD geometry (polylines, arcs, lines) and then scale the vector geometry , not the raster image. The raster remains as a visual reference only. The next time a client emails you a
