Secondary development method of cloud CAD platform based on B/S architecture

Abstract

The invention provides a secondary development method for a cloud CAD platform based on a B / S architecture, and the method comprises the steps: starting an integrated development environment under a UI condition set in a cloud CAD working space, and carrying out the program editing; in response to an editing operation of a user in the integrated development environment, starting a code verification module and a scene space which run synchronously; after an editing completion signal of the user is further detected, the code verification module carries out grammar verification on codes in the integrated development environment; the method comprises the following steps of: verifying a code, sending the verified code to a server side, carrying out code analysis and execution by the server side, returning an execution result in real time, and displaying a model represented by the execution result in a scene space to a user in real time. By adopting the scheme, the defect of insufficient practicability of the existing development technology is overcome, an additional development environment does not need to be built, an API is flexibly organized, debugging and execution of the program are conveniently and efficiently realized, the execution security is high, and the method has the characteristic that the method does not influence each other when being used by multiple users.

Description

technical field [0001] The invention relates to the technical field of system secondary development and optimization, in particular to a secondary development method of a cloud CAD platform based on a B / S architecture. Background technique [0002] CAD (Computer Aided Design), as a computer-aided design tool, uses computers and graphics devices to help designers perform various types of design work, and is widely used in engineering and product design in different fields. The secondary development of CAD tools is one of the research directions in the field of computer-aided design. [0003] With the continuous development of the CAD platform, its secondary development technology also needs to be updated in a timely manner. Most of the traditional CAD systems are stand-alone modeling tool software. The working method of the secondary development is: open an appropriate amount of Geometric modeling API interface, users can implement their own functions based on its open inter...

AI Technical Summary

Problems solved by technology

[0004] 1). The user cannot directly operate, modify and edit the server program on the browser side;

[0005] 2). The server-side program needs to run all the time, and it is used by many users at the same time, so it is not suitable for the interruption and restart process caused by compilation;

[0006] 3). The security of the platform system cannot be guaranteed during the secondary development process. User programs need to be executed in an independent environment, and it is impossible to avoid the impact of a user's program on the use of other users or the internal operation of the system;

[0007] 4). It is difficult to give full play to the advantages of convenient functions of the cloud platform, and it is impossible to realize the convenient sharing of programs among different users
