1. Civil Drafting Carlson CAD software Sanjeev Adhikari, PhD

2. Map Scale 1” = 10’1”=20’1” = 50’ Map is drawn in 1” = 50’ What is drawing distance of 200 ft actual length? Find Scale factor? Scale factor is 600 Drawing distance = 200 * 12/600 Answer = 4”

3. Map Scale 1” = 10’1”=20’1” = 50’ Map is drawn in 1” = 20’ What is drawing distance of 200 ft actual length?

4. Map Scale 1” = 10’1”=20’1” = 50’ Map is drawn in 1” = 50’ What is actual distance of 5” drawing length?

5. Map Scale Actual distance = 300’ Drawing distance = 5” drawing length? What is map scale?
