Urban planning and design based on autocad to expand gis function

Computer-aided design is more and more widely used in urban planning and design. Compared with traditional manual drawing, it has the characteristics of easy modification, easy transmission and communication. The advantages of using AutoCAD to assist urban planning and design are introduced, as well as some techniques of AutoCAD software in urban planning and drawing, such as the application of layers, raster image references, tiles, table making, and virtual printing. First of all, this article detailed the content of urban master plan, the requirements of the results, and the relevant content of AutoCAD urban planning software, and analyzed the application development process and application content of AutoCAD urban planning software in urban master planning in detail. The example part takes villages and towns as an example, and takes the overall planning results as the basic goal. It compares the application of AutoCAD in each stage of the overall planning in detail, and demonstrates the specific ideas and steps of AutoCAD for planning, thereby analyzing the advantages in the overall planning and design process. The technical process of AutoCAD-assisted master planning was obtained. © 2020 CAD Solutions, LLC,.
