Constructing of Structure in "Street-Drawings" by Freehand

There is no street-drawing without the task of detailing also some facades in it. We should study the original web of basic lines belonging to facades in the foreground from a frontal position, too.

There is no street-drawing without the task of detailing also some facades in it. We should study the original web of basic lines belonging to facades in the foreground from a frontal position, too.
While drawing a street wall with broken frontline in perspective, every facade will have its own vanishing point.
The coordinates of breaking points in the main outline should be compared by horizontal and vertical projections to starting scales.
Let's construct a Vertical Scale first before determining structural oblique lines (e.g. by detailing a near "column of windows" or a corner's edge)!
If the position of a Vanishing Point seems to be uncertain, we analyse the virtual slanting of the Extreme Oblique Line. Later we let run the oblique lines "in-between" toward an imaginary corner of angle.
Standing on street level, the basement edge (sidewalk) seems to be more flat than that of the highest gutter (eaves).
We should determine the exact position of our eye level by casting a glance aside considering the subdivisions of the nearest façade.
In Freehand Drawing new lines arise as if from "being woven", that is to say they will find their final place in the picture by being compared to some other lines arised earlier.
