A drawing apparatus is connected to a compound design apparatus. The design apparatus includes at least a display for displaying a drawing, a data base device for storing therein reference data to analyze the drawing, a storage for storing therein analysis data of the drawing, and a computing unit connected to the drawing apparatus to analyze the drawing. The computing unit may include a drawing evaluating section for extracting a graphic image of a particular mechanism part from the drawing generated by the drawing apparatus and for evaluating the graphic image, an analysis model generator for generating, according to a profile of the graphic image, an analysis model having a mechanism equivalent to the graphic image, an analyzer for reading mechanical characteristic data from the data base device, supplying the data to the analysis model, and analyzing the mechanism, and an analysis evaluating section for evaluating analysis results attained from the analyzer. The analysis results evaluated by the evaluating section are delivered to the drawing evaluating section, thereby evaluating the mechanism part graphic image.
