Compared with traditional CAD, BIM is really how much progress

What are the differences between CAD and BIM

1. The concepts are different.

Building Information Modeling (BIM) is a new tool for architecture, engineering and civil engineering. It is to describe those three-dimensional graphics-based, object-oriented, architecture-related computer-aided design.

Computer Aided Design (Computer Aided Design) refers to the use of computers and their graphic equipment to help designers carry out the design work. yd119.cn/article/917

2, the characteristics of different.

BIM has the following characteristics: it can be applied not only in the design, but also in the whole life cycle of the construction project; design with BIM is digital design.

CAD designers usually start designing with sketches, and the heavy work of turning sketches into working drawings can be given to computers; the design results automatically generated by computers can be quickly made into graphics, allowing designers to make timely judgments and modifications to the design.

3, different functions.

BIM model can not only draw conventional architectural design drawings and component processing drawings, but also through the visual display of the building, coordination, simulation, optimization, and produce professional drawings and deepening drawings, so that the engineering expression is more detailed.

CAD first of all it is a visual drawing software, many commands and operations can be achieved in a variety of ways such as menu options and tool buttons. Such as entity drawing, key point editing, object capture, labeling, bird's eye view display control.
