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

Nathan,

This solution is a bit strange.. it was probably something else you did. You should be able to use the hidden waypoints in the survey routine. Send me your flight plan if you want and I can help.

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).

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.
