Programming graphical objects and information in engineering drawings

Abstract

This article introduces you to graphics programming in the AutoCAD environment. Using Visual Basic Application programming language prepared methods and procedures for solving these design problems: attaching, reading and fulfilling mathematical operations with information extended data of a graphical objects. All information about drawing in the AutoCAD system is in the drawing database. We will study it in Drawing Interchange Format (DXF), which is in many graphical systems. Algorithms are formed to attach database record information to a graphical object, to read the information from graphical objects and to create objects specification in the drawing. The prepared example shows framework drawing with specification and database with steel information written in Visual Basic Application programming language. The general purpose of this paper is to contribute to such a debate about possibility of Visual Basic Application graphics programming in engineering education..
