using the AutoCAD commands the necessary editing and 
the completion was made for 
- the details which were not easily restituted on the 
rectified photos, i.e. decorative elements under the 
balconies or on the corners, cornices with a relief, rails 
etc 
- the various planes and slopes of the ceilings and the 
remaining elements which exist on the roofs (i.e. 
chimney). 
The result of all this effort was the 3D model production of 
the whole external figure of the building and the ability of 
producing the facade plans just by simply selecting the 
plane of each facade and projecting the stereomodel on a 
plane (X, Z) parallel to that particular facade. Also, the 
production of perspective plans from any point of view can 
be easily made. On Fig. 8 an output of such a plan which 
shows the southeastern side of the building from an angle 
of 22? above the horizon is given.

information about the exposure conditions or control 
points, but only some elementary metric information 
concerning the object of interest, can possibly lead to the 
compilation of detailed plans, even to a 3D modelling of the 
object, with an acceptable accuracy, of course always 
dependant on a number of factors.
