A Method of Aided Planning and Design Based on Autocad General Graphic Objects

Abstract

The invention discloses a method for realizing auxiliary planning and design based on AutoCAD general graphic objects, which comprises the following steps: Step 1, establishing the corresponding relationship between graphic elements and graphic entities of planning and design. Step 2, establishing a graphic entity model of the physical object. Step 3: Read the graphic entity model established in Step 2 through the secondary development interface of ObjectARX for planning and design. The present invention adopts the above-mentioned technical scheme, which is more open and versatile, saves time, improves efficiency, and guarantees application compared with various planning aided design methods currently used in the planning and design industry, and has broad application in the planning and design industry. Application prospects.

Description

technical field [0001] The invention relates to the field of planning and design, in particular to a method for realizing auxiliary planning and design based on AutoCAD general graphic objects. technical background [0002] Planning and design is a complex systematic project. In addition to compiling planning texts, it is also necessary to draw a large number of planning drawings. There are multiple rounds of adjustment and update in the planning process. Planning designers are bound by a lot of low-level drawing work. The emergence of planning aided design software has liberated the hands of planning designers to a certain extent, improved the efficiency of compilation, and standardized the format of results, allowing planning designers to devote more energy to whether the planning itself is reasonable and scientific. thinking. [0003] For a long time, the drawing platform for planning and design drawings has been mainly concentrated on the AutoCAD software platform of Au...

Problems solved by technology

Among the many auxiliary software, some of the software is just a simple integration of some functional tool sets, and the application scope is very small, which cannot completely support the whole process of urban planning and design; the other part is planning aided design software developed by professional software companies. The process support is more comprehensive, and the system integration is also higher. However, in order to improve the drawing efficiency and bind users more closely, the software adopts a large number of "AutoCAD custom object" technology, and the software developed by using this technology draws A graphic object is not a general AutoCAD object entity. It is necessary to install a dedicated analysis program on the corresponding computer client to perform display, browsing, copying, and other editing operations on the graphic object.

Due to the setting of too many technical thresholds and barriers, the versatility and usability of the planning and design drawings drawn by it are greatly reduced, and they cannot be used on computers that do not have the corresponding parser installed, and the graphics results drawn by different software cannot be used universally. It is difficult to convert the drawn graphic results to GIS, and it is more difficult to use the results
