With the rapid development of the scientific and technical level, people have new requirements on the residential conditions, and meanwhile, the building quality problems in the building industry are increasingly highlighted. The nature of the construction quality problem is the design problem of the construction drawing, so drawing examination is a very important link. At present, CAD software is commonly used in the building design industry to draw drawings, and manually drawn drawings need to depend on engineers or special auditors with abundant experience to judge whether places which violate the national building standards exist in the drawing design, so that the drawing inspection work is quite different due to personal project experience, knowledge storage and working life, and a great deal of manual work also causes that the audit work cannot establish a perfect flow. Secondly, five major professions of building, structure, water supply and drainage, heating ventilation and electricity are divided in the drawings, the drawings cannot be examined singly, if engineers according to different professions carry out according to the working procedures of three-correction and two-examination, the drawing examination time is very long, and even the life cycle of the building is influenced.
