How to create road surface by DynaMaps in areas with incomplete data from open map

Hi There,
I was trying to make road surfaces and project it onto topography, in an area with incomplete data from Open Maps I had to generate some data manually.
Road Surface.dyn (28.2 KB)

I made road surfaces in the XY Plane but for some reason, I can not understand some of the surfaces have been made in the wrong plane, therefore I get an error in the very last step where I supposed to get a projection of the surfaces over the topography.

I do appreciate it if you could help me to fix this error.

Your time and help are highly appreciated in advance.

Best Regards,
