Установление связей между элементами базовой сети при параметризации чертежей

Установление связей между элементами базовой сети при параметризации чертежей

Abstract

The problems of creating a parametric model of drawings on the basis of the creation of its core net-work are discussed. The core network is formed using the characteristic points of the basic graphics primitives of the draft. Creating the model is based on the method of the analytic-synthetic parameterization using the processing of size designations employed in the drawings. Features of algorithms for processing various dimensions on the engineering drawings are presented. Defining relationships between elements of the core network is used for modifications of the engineering drawings with the new values of dimensions.

Рассмотрены проблемы создания параметрической модели любого чертежа путем определения количественных связей между элементами базовой сети, образованной характерными точками основных графических примитивов. Создание модели ведется на основе обработки размерных обозначений, установленных на этом чертеже в соответствии с методом аналитико-синтетической параметризации. Изложены особенности алгоритмов обработки различных размерных обозначений, имеющихся на чертеже. Установление связей служит для обеспечения модификации чертежа с учетом задания новых значений параметров.
