Re: [Paparazzi-devel] Unusual issue with Polygon Survey - Bug or Feature?

[Nathan Aherne]

Hi Chris,

I have changed the flight plan now and its working (except for the sectors 
part, which is probably a newbie issue). What I had done was have five 
waypoints called SA1-5 and five hidden waypoints _S1-5. When I removed the 
hidden waypoints, and changed the Polygon survey to use the non hidden 
waypoints it worked without a hitch.

You can see the waypoints in the screenshots, and its convex (I think).

Kindest regards,

Hi,

got both emails, the first one wasn't blocked.  I think from your
description that I understand the symptom, but I don't know cause
because I haven't seen it before.

Are you sure your polygon is convex? if the waypoints are hidden,
maybe they are  not where you think they are... That's just a guess,
please attach the offending flight plan.
