Parametrization of a technical object in solid edge

This paper presents the core of the elaborated system of automatic generation of design documentation for a family of technical objects. An indispensable element of the system are commercial CAD 3D computer tools. The method of using parametric models of objects for automatic generation of the design and technological documentation (to the limited extent) of the modelled equipment has been presented. Implementation of the system made it possible to execute orders for production of the equipment submitted by the clients who require (other than standard) features of an object. All the considerations have been illustrated on the basis of the devices intended for the companies dealing with production and distribution of cables. Assumptions and design solutions for a cable rewinder have been elaborated. An algorithm of a process of preparation of the design documentation for various variants (series of types) for the designed equipment, on the basis of a prepared three-dimensional parameterized model of an object, has been elaborated. The suggested solutions and elaborated programming tools have been implemented in practical applications. Placing the consecutive variants of the equipment on the market, in the production system under analysis (a real enterprise), was connected with manual modification of recording the designs of most of the parts of the base MCAD (Mechanical Computer-Aided Design) model of the specific product. The above solution resulted in design-and-technological errors, most of them being detected only at the production process stage. It was linked with longer term of execution of an order and with bearing additional costs. Implementation of the suggested system contributed to shortening order execution term, reduction of the equipment production costs and elimination of errors in the design documentation.
