Module for description of lines in technological processes of manufacturing gas and oil engineering products
The article substantiates the modular approach to the development of CAD elements for technological purposes, describes the structure of the module, the tools that allow a formalized description of the set of lines of a technological operation and record the results of the description in the design tasks database. A description of a fragment of a design task by the CAD tools in a specialized programming language is considered. A description of the operators of the de-sign task is given, the formal parameters of these are used as formal parame- ters of the line description operator - masks (formalized description of the string in the operation of the technological process). The expediency of using the description of mask strings in the text of the design task of operators is shown, since at the start of the design task formal parameters in the operators are replaced with their values. This allows to automatically generate a description of the lines of operation of the technological process, the format of which cor- responds to the requirements for the preparation of technological document- tation.
