After reading the in depth article about drawing lines (SID's/STAR's) I have decided to practice this on KDFW.
The goals are to practice, one runway out of the seven at a time, and then eventually model the airport scenery, to help make North America a decent looking location. (but that is a separate task
More important, if anyone has any pre-existing SID/STAR files for OpenRadar for KDFW that they would be working on, please message me so work is not duplicated.
Thank you!
