Hi, I just made a trip to Spain, and I would like to build routes out of logs - I fly low and following the valleys it will be useful to keep the logs as routes if I repeat the same flight. Can it be possible to make it ? I didn't find the way.

There's no tool in SkyDemon to do it. Such a route would likely have a HUGE number of waypoints in it, and that might slow SkyDemon to a crawl. You might be able to find a tool to convert from a log in GPX format to a route in GPX format, then import that back.

Is it not possible to make a new route using the displayed flight log as a guide?

Yes, and that may avoid the excess of waypoints that will appear using directly the log.
