Query: The Features of the Complex CAD system of Reconstruction of the
  Industrial Plants   The features of designing of reconstruction of the acting plant by its design
department are considered: the results of work are drawings corresponding with
the national standards; large number of the small projects for different acting
objects; variety of the types of the drawings in one project; large paper
archive. The models and methods of developing of the complex CAD system with
friend uniform environment of designing, with setting a profile of operations,
with usage of the general parts of the project, with a series of
problem-oriented subsystems are described on an example of a CAD system
