Embodiment Construction

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0038] combine Figure 1 ~ Figure 3 As shown, the present invention discloses a method and device for displaying CAD drawings without plug-ins at the front end of the WEB. By analyzing the CAD drawings at the server, the front-end client uses Javascript scripting language to draw CAD drawings in the Canvas control, so that the front-end client does not have any plug-ins. The plugin displays CAD drawings.

[0039] combine figure 1 and figure 2 As shown, a method for displaying CAD drawings without a plug-in on the front end of the WEB disclosed by the embodiment of the present invention includes:

[0040] Step 1. The server reads and analyzes the CAD drawing file requested by the client, and analyzes all the CAD objects and their attribute values ​​contained in the CAD drawing. Aft...

Abstract

The invention discloses a method and a device for carrying out the no-plugin display of a CAD (Computer-Aided Design) drawing on a WEB front end. The method comprises the following steps that: a server reads and analyzes the CAD drawing requested by a client side and analyzes all CAD objects contained in the CAD drawing and the attribute values of the CAD objects, and all object data is packaged into a Json data / XML (Extensive Markup Language) data format after analysis is finished, and are sent to the client side; and the client side adopts a Javascript script to analyze all CAD objects and the attribute values of the CAD objects in the Json data / XML data, the coordinates of the CAD objects are converted into the coordinate of a local Canvas control, and the CAD drawing is drawn in the Canvas control. By use of the method, the no-plugin display of the CAD drawing on the WEB front end is realized, all mainstream browsers, operating platforms and systems can be compatible, and the device is easy in development and popularization.

Description

technical field [0001] The invention relates to a technology for displaying CAD drawings at the front end of a WEB, in particular to a method and a device for displaying CAD drawings at the front end of the WEB without plug-ins. Background technique [0002] At present, the basic method of displaying CAD drawings on the front end of the WEB is to install a CAD plug-in, and the browser downloads the CAD drawings from the server and loads the plug-in for display. This CAD drawing display method has the following two disadvantages: [0003] 1. Due to the wide variety of browsers and the different interfaces provided by browsers, it is difficult to guarantee the compatibility of CAD plug-ins, and it is difficult to be compatible with all browsers. [0004] 2. Due to the existence of different operating systems and various platforms, the plug-in method cannot be compatible with all platforms and systems. Contents of the invention [0005] The purpose of the present invention ...
