How to make a flight plan

Please tell me how to make a beautiful figure-8 flight plan.

make it larger.
the render distance in MP is about 4m, as to not use 100% cpu. in reality it would be alot smoother than in the example

Thank you. What is the render distance?
I want to draw something close to a single curve.

you will need to calculate your point coords.

try turning on Grid so you have a scale to work against

It will definitely be distorted.
