I just did not really want see two people making two sets of 3d parts in two build treads. That are the same plane but different variants.
Do you realize you did the exact same thing again? Maybe you can't see your own behavior or you are unable to verbalize your intent properly. You could have said they should collaborate to save duplication but not say 'I just did not really want to see two people making two sets of 3d parts in two build threads'. You're telling two people what to do or suggesting it, if you want to argue wording, but either way it's not your place to do that. Actually I'm trying to help you whether it appears that way or not. I've seen you many times over the years tell others what they should or should not be doing like you are a controller of the forum. You aren't.
The low cost 3d program Donamy said he uses often creates parts with lines running in odd places it's not like what you get with 3ds Max. Donamy would you be interested in posting an fbx export of your plane? That way if technoid chooses to model the AT-802U he can see if any of your parts are usable for it.
I am trying to be a nicer guy but I'll admit I don't care to see one person telling others what to do. Most people choose not to confront it or call it something else, but inside themselves they really know what it is.
