Problems solved by technology

First build a 3D model and then convert it into a 2D production drawing. This design method requires a high level of ability for the designer to manipulate 3D software, and the cost of modeling is high, making it difficult to modify.
Due to the busy business, many design tasks and many changes in design schemes, it is not easy to modify the 3D model, and the quality of personnel is limited, so the use of 3D software in most companies and enterprises is mostly in a semi-suspended state
Because the 3D software has many bugs, it is difficult to control; the 3D model has a large amount of data and occupies a large amount of memory; therefore, the speed of 3D modeling is slow, and the computer runs slowly

Embodiment Construction

[0042] The hardware configuration of the computer in the present embodiment is: more than 915 mainboards of the computer, dual channels of memory data; two memory 512; CPU: more than 2.4G; more than Geforce6200 graphics card; more than 8M hard disk cache. The graphic design module of the computer is Pro / ENGINEER 3D software of PTC Company, which has the function of accepting variable parameters and displaying variable parameters and their values ​​in graphics, and the annotation function in the layout of the 3D software has the best effect good. The computer also has another graphic design module as required, which is AUTOCAD. The reason for using AutoCAD is: in view of the poor time-consuming and labor-intensive two-dimensional drawing function of Pro / ENGINEER three-dimensional software, the two-dimensional drawing control function is relatively unsatisfactory, and relatively Compatible with the dxf file of R14 AutoCAD, and AUTOCAD has strong two-dimensional drawing functions...

Abstract

The disclosed method to auto design and adjust engineering graph comprises: building and storing the 2D master control graph with some elements set as the controllable variable parameters and generated variable parameters, and creating the relation formula between parameters as knowledge rule design method; recalling the graph to input new value for controllable parameters and calculate new parameter values by computer, and then auto generating the production graph by a computer. This invention can improve 10-100 times for the design speed compared to the 1-2 months time by common technical staff.

Description

Technical field [0001] The invention relates to a system for automatically designing and adjusting engineering graphics, its establishment method and its use method. Background technique [0002] At present, many designs mostly use: people get the result value of engineering graphics according to a certain knowledge rule and calculator, and then manually enter it into the electronic drawing board to obtain product design and production drawings. This design method is time-consuming and prone to human error. [0003] In order to shorten the design time, avoid human error, and reduce the waste of manpower and material resources in the production process, companies and enterprises try to use 3D software to solve the problem. The 3D model is established first, and then converted into 2D production drawings. This design method requires extremely high ability of the designer to manipulate 3D software, and the modeling time and cost are high, and modification is not easy. Due to ...
