The most common cause of difficulty when using the offset command is not responding to the command line prompts for "specify offset distance" correctly.
Two alternative inputs are available at this point. You can type in a value for the offset (Keyboard entry must be followed the enter key) or you can pick any 2 points on the screen. In this latter case Autocad uses the distance between the 2 points for the offset.
This is one of those commands that carries on until you push right mouse to finish. So you can do multiple offsets with the same distance if required. If the distance needs to change, you must stop and restart the offset with it's new distance.
To measure the arc length click and grip the arc, push right mouse and pick properties.
