I'll have a look, but I think, the DEVs seem to overcomplicate this problem. There's a problem when SRIDs of source layers aren't equal. So the simplest solution is to show a messagebox that results won't be metric when one or both of the SRIDs aren't in a metric projects. The proper solution would be to switch to a geodetic length. I can give advices to a developer, how to do this. > As a side not, please avoid using provocative terms: everyone here is > doing his best, and donate their work to the world at large. > All the best. Sorry, I don't see a problem here. QGIS is telling, output will be in meters, but it isn't - so it's a lie. The worst thing is that there is no warning about the output NOT being metric. This will make interpretation of the data or automatic post-processing be invalid. I'm also doing hard work to make QGIS being accepted in the educational world, but those problems make the users think "Why change?".
