This designing realized the automatic designing of engineering drawing and automatic extracting of information.
In addition, it implemented the automatic drawing of engineering diagrams and access to information in railway signal engineering design.
Reading Information to Engineering Drawings.
During the engineering design of the signal,it is necessary to read many types of information of engineering drawings, including statistics track section of the signal, the number of transponders and graphics information conversion and so on, which use graphic objects to traverse.
The application of the AutoCAD secondary development technology in computer aided design not only improves the efficiency and accuracy of drawing, but also greatly dispenses with much labor, which will definitely be an inevitable result in the future areas of civil engineering,mechanical engineering and Traffic and Transportation Engineering.

A new trend for reverse engineering: robotized aerial system for spatial information management Jesús Fernández-Hernandez1, a, Diego González-Aguilera1, b, Pablo Rodríguez-Gonzálvez1, c and Juan Mancera-Taboada1, d 1 Cartographic and Land Engineering Department.
Nowadays, the evolution of the electronics and new materials has provided the use of low cost unmanned aerial platforms (UAVs), which permit to obtain aerial images to derive competitive geomatics products in the different reverse engineering fields.
Thus, the use of UAV’s has been expanded notably in the reverse engineering field, mainly for works where other technologies, such as conventional aerial photogrammetry [4], remote sensing [5]; or topographic methods [6] are not enough of adequate.
However, compared with UAVs for military purposes, the civil UAV’s will require the following features: low cost and size; development focused on specific demands, and high-quality results.
The key to success lies on flight planning, since allows us to optimize field work accomplishing several geometric requirements which are mandatory in some applications such as engineering and architecture.

Engineering supervision system in our country has developed for twenty-four years, has become a basic system in engineering construction, was formally incorporated into construction method, therefore the development of supervision industry into the legal track.
But in engineering construction supervision, despise the idea still generally.
Engineering do well construction unit 's credit; do not, it is the responsibility of inspect manage unit, the owners were blamed for the supervision efforts not to reach the designated position, often be the owner as a scapegoat; construction units to inspect manage engineer command will also turn a deaf ear to, refused to perform.
The owners as their own tools, can only represent their interests, project management in the site inspection, engineering measurement and data collector.
Construction supervision responsibility includes civil, administrative, criminal three class.

Introduction Geotechnical engineering is a speciality of Civil Engineering which deals with the properties, behaviour and use of earth materials (soil and rocks) in engineering works [1].
Determination of soil conditions is the most important in civil engineering works.
Understanding the behaviour of various soils is an important concern to the engineer.
So it is important for engineer to know how various soils behave in solving geotechnical problems.
