Practice of non-graphical object xrecord in engineering design

Abstract

The problems of automated design system with using object xrecord are researched in the article. Two parts of drawing are separated: graphical objects (lines, circles, polygons, ellipses, and so forth) and non-graphical objects (layers, linetypes, dimstyles, selectionsets, xrecord etc). A question, how non-graphical objects xrecord is used for graphical programming, is analyzed. Literature about non-graphical objects usage for designing engineering systems is presented and examples using Visual Basic for Application programming language are referred. Finally, the conclusions are made.
