Design and Optimization of CAD System for Building Construction Drawings based on BIM

Abstract

In the course of evaluating and analyzing the effectiveness of CAD system, it is difficult to analyze the construction data automatically by means of image. On the basis of these, the article researches the CAD system of architecture layout and its optimizing approach using BIM technique. This paper sets up an efficient evaluating model for CAD system in the construction planning by using Tabu Search Method. Based on Web of Things and BIM techniques, we set up a variety of CAD graph groups for the construction planning. Based on the needs and data of various building items, we can analyze the CAD system efficiently, and then we can evaluate the precision and suitability of the CAD. It is proved that the IOT technique can be utilized efficiently in constructing CAD system with Tabu Search Strategy. According to building items, BIM technical plan is chosen, which is the most suitable for CAD drawing. Therefore, the total reliability of CAD system can be increased efficiently.
