| In the field of engineering design, CAD technology greatly enhanced the efficiency of design and graphics. Application of AutoCAD as a wide range of computer-aided design software, has excellent graphics and a two-dimensional three-dimensional image rendering capabilities. Water Supply and Drainage in the secondary development of CAD professionals to improve the degree of automation to improve the calculation precision and speed, to avoid duplication of data input, improve the design efficiency, water supply and drainage design for an extremely important practical significance and application value. Papers of AutoCAD customization and secondary development to better meet the design requirements for drainage.Customization of AutoCAD, added dozens of line to meet the actual needs of users of water supply and drainage. The development of AutoCAD-based drawing system to simplify and extend the order, making no input or simply enter a few parameters will be able to auto-complete the mapping and multi-step modification. These commands have been customized into a drop-down menu or custom toolbar for intuitive operation. CAD graphics with the establishment of the corresponding external database of direct contact information so that users can click the graphic entities direct access to, modify the graphics attached to information, easy access and management. In order to design an intuitive understanding of the information network, the system set up a database of pipe sections. As an essential element of network management information section of pipe sections including the number, length, diameter, pipe flow, part of the source of the data from the user's original input, part of the calculation results from the procedure. Procedures for the realization of that is simply click the corresponding pipe sections, pipe sections can be enacted in the form of information to view the required data.As the programming of friendly CAD interface that is suitable for the users of,designers of Water Supply and Waste Water profession are able to work thought this interface,which greatly makes the users convenient while using this software. |
