Sweep Constructor - 2

I have done all the easy things now for the Sweep Constructor. There were still some small issues with profile editing, but those are solved now (a missing matrix). Also the constructor actually creates geometry now. It only works with paths of length 2 and only with path that are running along the y-axis. I have also thought about how to change the path, I don't want to input the paths in 3d, I already know that that is hard. So I try something different, the path is projected onto two planes (xy-plane and zy-plane) and I will edit the path on those projections. I don't know if it will work, but I think it might be a good way. The projections are already displayed and also a grid is placed behind those projections.

As I don't see any useful way to combine editing of the profile and the path, I think I will separate the selections and editors. I have never tried that and am not 100% sure I can do that in my current model, but I think it should work. That would show a path for future modifiers which should make it possible, to create complex editing behavior from smaller building blocks.
