Automatized formation of specifications in engineering drawings

Abstract

Formulation of problem Prepared methods and Visual Basic Application (VBA) procedures for solve these design problems: creates matrix with graphical objects' names and numbers, in order to find a list of similar graphical objects; creates elements' specifications in the drawing. The following procedures are presented: procedure fragment which calculates the number of graphical objects and writes objects' names to a vector string, the next procedure finds the same names of graphical objects in vector and calculates their number, this new information is written to matrix, in which the first column has names of graphical objects from drawing database (DDB) and the second column has the corresponding number of these objects. The presented examples of procedures show that it is possible to control names and numbers of graphical objects in the drawing. Using this technology in the engineering drawings, we can automatically design specifications of drawing elements.
