Google Earth Pro (free for desktop) solves the two biggest problems of screenshots: it maintains geographic coordinates and allows export of georeferenced images.
Now that you have the image file, it's time to import it into AutoCAD:
This feature explores every method to scale a Google Map in AutoCAD—from the quick manual reference to advanced geolocation tools—while tackling the hidden challenges of distortion, resolution, and coordinate systems. how to scale google map in autocad
The most effective methods to achieve a 1:1 real-world scale involve the command with a reference or the ALIGN command to match the image to a pre-drawn line. Step 1: Capture the Map Image Correctl
: Right-click on a known object (like a building edge) in Google Maps and select "Measure distance" . Note this exact length (e.g., 50.5 meters). Step 2: Import the Image into AutoCAD Google Earth Pro (free for desktop) solves the
Now that you have the scale factor, you can apply it to the image:
This reduces the seven-step process to three clicks and one number. Step 1: Capture the Map Image Correctl :
(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) )
By following these steps, you can successfully scale Google Maps in AutoCAD and take advantage of the benefits of integrating these two powerful tools. Happy drafting!
