چکیده

Обсуждается развитие методов автоматизации подготовки чертежей на основе так называемых модулей, содержащих одновременно параметрическое представление части чертежа и соответствующие геометрические элементы. Как этапы эволюции модульной технологии автоматизации проектирования рассматриваются варианты применения модулей для простого объединения элементов без параметрического представления с возможностью комментирования, для генерации условных графических обозначений в схемах автоматизации и чертежей трубопроводов, для хранения специфицирующих свойств изделий, для разработки специализированных частей проекта: аксонометрические схемы, профили наружных сетей и др.

Repairing CAD model errors based on the design history

For users of CAD data, few things are as frustrating as receiving unusable, poor quality data. Users often waste time fixing or rebuilding such data from scratch on the basis of paper drawings. While previous studies use the boundary representation (BRep) of CAD models, we propose an approach to repairing CAD model errors that is based on the design history. CAD model errors can be corrected by...

A Genetic Algorithm based Optimization Method in 3D Solid Reconstruction from 2D Multi-View Engineering Drawings

There are mainly two categories for a 3D reconstruction from 2D drawings: B-Rep and CSG that both these methods have serious weaknesses despite being useful. B-Rep method which has been older and have wider function range is problematic because of high volume of calculations and vagueness in answers and CSG method has problem in terms of very limited range of volumes and drawings that it can an...
