Now, some data sources do not list dimensions directly, but as “Station Numbers” (often with a “STA” prefix). So you have to work out the particular dimensions between any two given station numbers. It’s not hard, just different.

If I have a scale drawing with station numbers, how do I convert that to actual dimensions ? Can you provide some examples how to do it?
