Abstract

Methods, apparatuses/systems, and software for converting graphic objects representing two-dimensional beams or columns within a drawing into three-dimensional beams or columns by locating all attribute labels within the drawing containing beam or column information, locating all two-dimensional graphic objects corresponding to the attribute labels, converting the attribute labels to simple text without Unicode formatting, and converting each two-dimensional graphic object into a three-dimensional graphic object based on the corresponding simple text.
