Hello! Welcome to our forum and sorry for the delayed answer - this post went under our radar!
What format are you trying to export? The MSFS PLN format requires airport identifiers for both the origin and destination to work - we can’t provide coordinates (such as user waypoints) in this case. You can see the full specification for this file here:
Thanks for your answer and after reading the definitions for an MSFS PLN i get what you mean.
For fun i tried to hack a .pln and set the custom waypoints as airporttypes and then import that in MSFS2020 i tought i worked, but when starting the flight im in the air. If only we could force the sim to not set the departure and arrival as “AIRBORNE- 0 FT”.
Well again thanks for your answer.
Best regards
Thomas
