Vertices on edges of a building structure often ment to be on the same level:

- a ridge, the top intersection of two opposite adjoining roof surfaces

- eaves, the intersection of the roof and the wall

- parapet alongside a flat roof

- handrails on a terrace

- the terrace surface

I hope the program will make vektorizing such datails more effective.  
Right now it gives us individual 3D-coordinates no matter whether is a line made by nature or by man.

In a dream scenario, when the polygon vectorizing is finished, the program should promt for input:  
"Are the line vertices on the same level ? If the answer “Yes” then a second promt should appear:  
"Which height should be assigned to them ? Height of the first/last vertex or an average ?

Later, if one of the vertices of such a polygon is inspected and the height is altered, the height of all other vertices should also change accordingly.
