The experience of automation of the specifications making of the projects of renovation of the industrial enterprises is described, being based on the special modules in the drawing containing the visible image and additional parameters, and electronic catalogues
According to the requirements of the Russian standards, the automation schemes are necessary practically in each project of renovation of industrial buildings and facilities, in which any technological processes are realized. The model representations of the automation schemes in CAD-system TechnoCAD GlassX are described. The models follow a principle "to exclude a repeated input operations"
The main ideas, data structures, structure and realization of operations with them in environment of development of the programs of parametric creating of the drawings are considered for the needs of the automated design engineering system of renovation of the enterprises. The example of such program and example of application of this environment for creating the drawing of the base for equipment in CAD-system TechnoCAD GlassX are presented
The threats to security of the information originating owing to involuntary operations of the users of a CAD, and methods of its protection implemented in a complex CAD system of renovation of firms are considered: rollback, autosave, automatic backup copying and electronic subscript. The specificity of a complex CAD is reflected in necessity of rollback and autosave both of the draw and the parametric representations of its parts, which are the information models of the problem-oriented extensions of the CAD
Progressing methods of drawings creating automation is discussed on the basis of so-called modules containing parametric representation of a part of the drawing and the geometrical elements. The stages of evolution of modular technology of automation of engineering are describing alternatives of applying of moduluss for simple association of elements of the drawing without parametric representation with an opportunity of its commenting, for graphic symbols creating in the schemas of automation and drawings of pipelines, for storage of the specific properties of elements, for development of the specialized parts of the project: the axonometric schemas, profiles of outboard pipe networks etc.
The modular technology of development of the problem-oriented CAD expansions is applied to a task of designing of profiles of outside networks of water supply and water drain with realization in program system TechnoCAD GlassX. The unity of structure of this profiles is revealed, the system model of the drawings of profiles of networks is developed including the structured parametric representation (properties of objects and their interdependence, general settings and default settings) and operations with it, which efficiently automate designing

The system model of the drawings of lightning protection is developed including the structured parametric representation (properties of objects and their interdependence, general settings and default settings) and operations with it, which efficiently automate designing
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 TechnoCAD GlassX
The methods of support of the requirements of the Russian standards in a CAD of industrial objects are explained, which were implemented in the CAD system TechnoCAD GlassX with an own graphics core and own structures of data storage. It is rotined, that the binding of storage structures and program code of a CAD to the requirements of standards enable not only to fulfil these requirements in project documentation, but also to increase a degree of compactness of storage of drawings both on the disk and in the RAM
The parametric model of build constructions and features of design operations are described for making drawings, which are the common component of the different parts of the projects of renovation of enterprises. The key moment of the deep design automation is the using of so-called units in the drawings, which are joining a visible graphic part and invisible parameters. The model has passed check during designing of several hundreds of drawings
The characteristic of design works on firm at its renovation and of the common directions of their informatization is given. The implantation of a CAD is selected as the key direction, and the requirements to a complex CAD-system are stated. The methods of such a CAD-system development are featured, and the connectedness of this development with the process of integration of information space of design department of the firm is characterized. The experience of development and implantation of a complex CAD of renovation of firms TechnoCAD GlassX lies in a basis of this reviewing
The hierarchic block model of the tables in design documentation as a part of a CAD system is described, intended for automatic specifications making of elements of the drawings, with usage of the electronic catalogs. The model is created for needs of a CAD system of reconstruction of the industrial plants, where the result of designing are the drawings, which include the specifications of different types. The adequate simulation of the specification tables is ensured with technology of storing in the drawing of the visible geometric elements and invisible parametric representation, sufficient for generation of this elements.
Applying the modular technology of developing of the problem-oriented extensions of a CAD system to a problem of automation of creating of the axonometric piping diagrams on an example of the program system TechnoCAD GlassX is described. The proximity of composition of the schemas is detected for special technological pipe lines, systems of a water line and water drain, heating, heat supply, ventilating, air conditioning. The structured parametric representation of the schemas, including properties of objects, their link, common settings, settings by default and the special links of compatibility is reviewed.

The problem of the automation of the designing of the axonometric piping diagrams include, as the minimum, manipulations with the flat schemas of three-dimensional wireframe objects (with dimension of 2,5). The specialized model, methodical and mathematical approaches are required because of large bulk of calculuss. Coordinate systems, data types, common principles of realization of operation with data and composition of the basic operations are described which are realised in the complex CAD system of the reconstruction of the plants TechnoCAD GlassX.
The modular technology of creation of the problem-oriented extensions of a CAD system is described, which was realised in a system TechnoCAD GlassX for designing of reconstruction of the plants. The modularity of the technology is expressed in storage of all parameters of the design in one element of the drawing - modulus, with automatic generation of a geometrical part of the modulus from these parameters. The common principles of the system organization of extensions developing are described: separation of the part of the design to automize in this extension, architecture of parameters in the form of the lists of objects with their properties and links to another objects, separation of common and special operations, stages of the developing, boundaries of applicability of technology.
The concept of the "modulus" in the CAD system drawings is characterized, being a base of developing of the problem-oriented extensions. The modulus consists of visible geometric elements of the drawing and invisible parametric representation of the modelling object.
