All the measurement needs to be corrected. I know this video to learn about the drawing, but the video will be more useful if we have the correct measurement of the park and do what you did in the video.
Somebody 30 minutes explained me how difficult to convert 3D solidworks model to 2D drawing :-O You 19 minute video proves opposite! After watching it I made the drawing I need in 5 minute :-) Thank you very much!
