I’m new to SU and have started to learn it through one of the subscription tutorials. What I’d like to achieve is to convert the analog plans for a 12’ John Welsford SCAMP sailing dinghy into digital. I’ve included a photo of one of the bulkheads. Obviously, I require only 2D images, in millimeters.
How can I create an (x,y) coordinate system that allows me to measure from a baseline/centerline? Ideally, an ability to establish an (0,0) origin point that will allow the (x,y) coordinates to appear either next to the cursor or in the measurement box in the bottom right corner as the cursor moves would be very efficient.
Alternatively, is/are there a better way to make this digital conversion?
Thanks for your time.
