Automatically designable and adjustable engineering graphics system and its building method and using method

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 ...
