Key words: the Basic Web of Structural Lines, Horizontal and Vertical Projections, the Local Contrast, Extreme Oblique Lines (eaves, sidewalks), the Master Picture Plane, the Method of Subdividing the Picture Plane, Picture Plane Mosaic, Oblique Lines "in-between", the Procedure of "Detail-Heaping", the "Proportion Measuring" Method, Simple Geometrical Shapes (SGS), a Street-Wall with Broken Frontline, a Stripe of Windows / a Row of Windows, (near and remote) Vertical Scales.

     There isn't any 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.
     Coordinates of main outline's breaking points ought to be compared by starting scales with the help of horizontal and vertical projections.
     Before determining of structural oblique lines we should construct some Vertical Scales first (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 ought to analyse the virtual slanting of Extreme Oblique Lines. Later we'll send oblique lines of "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", finding their final location in the picture through comparison with some other lines arised earlier.
