So I am trying to make a site map for a building my buddy just bought. I found a lot map on the city's online database, cropped it to the area of his lot's block, and saved the image file. I then opened up a new autocad file and xreferenced the image. I know the front of his building on the site is 45' so I made a polyline that is the length of the facade over top of my xref image. Then I selected the image, used the scale command, selected one side of my polyline as a basepoint, used reference, entered 45' as the known length, and then selected the other end of the polyline. My image scaled but is now incredibly small. So small that the entine site isn't even 1". I keep trying but I'm doing something wrong somewhere. Can someone help me out?
