Description
Technical field
The present invention relates to the method for realizing CAD diagram paper online browse.
Background technology
As the development and popularization of network technology, people are growing to the demand of network application.Conventional CAD systems are
Can not meet the needs of people are to Collaborative Design, data sharing, most of network CADs are also limited to C/S model, can not
Overcome the shortcomings of installation upgrade maintenance is difficult, investment is huge.
The webization of software is the trend of following CAD software development.The demand of people promotes the development of internet, and mutual
The development of networking has deepened demand of the people to network again.Under the demand of network and the interaction of development, traditional software
Industry also receives huge impact.More shortcoming be present in traditional software：1st, software installation and operation need take client it is a large amount of
Hardware resource；2nd, the upgrading of software is inconvenient, difficult in maintenance；3rd, direct data sharing can not be realized with cooperating；4、
Function waste be present in many Large-scale professional softwares；5th, every computer needs separately installed copy, enterprise's application
Invest huge；6th, the bad adaptability in isomerous environment；7th, problem of piracy is serious, is very difficult to avoid completely copy right piracy.
The content of the invention
Present invention aims at provide the method for realizing CAD diagram paper online browse for the deficiency present in prior art
Technical scheme, by the way that CAD diagram paper is changed into Flash file SWF, and can directly be realized by online browse device system different
Browsing and designing for ground model, reduces the space occupancy rate of model data, improve online browse device system practicality and
Flexibility.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
The method for realizing CAD diagram paper online browse, it is characterised in that comprise the following steps：
1) CAD diagram paper is first turned on, and corresponding drawing content in CAD software interface is subjected to frame choosing and replicated；
2) Flash software is opened again, and the CAD diagram paper after duplication is pasted in Flash elements (film clip)；
3) then CAD diagram shape is repaired with toolbar in Flash software；
4) and then Flash action script programs are edited, realizes the Vector enlarging of CAD diagram paper, and dragged with mouse or touch-screen
The varying dimensions of cardon paper；
5) after the size after CAD diagram paper in Flash software determines, preserve file and generate CAD diagram paper Flash file
SWF；
6) online browser plug-in is finally installed, logs in registered user's name and password in the homepage of online browse device system,
Subsequently into online login page, by the Flash finished product file SWF embedded web pages of generation；
7) Flash file is browsed by web browser client, and according to the prompting download plug-in of browser, downloaded
After the completion of can be directly in the ID attributes and color attribute of web browser client interface modification CAD model, and be saved in use
On the computer at family oneself.
The online browse method can be not only avoided in CAD diagram paper downloading process, made because data flow is excessively huge
Do not responded to for a long time into client, and CAD model data can be obtained from the webserver to update at any time as needed
In the client, by the way that CAD diagram paper is directly translated into Flash file SWF, it is ensured that CAD diagram paper is undistorted after upload,
The definition of SWF files is improved, and can be changed by download plug-in and edlin is entered to CAD model, substantially increases CAD diagram
The editorial efficiency of paper, while the conversion between different CAD versions is avoided, make the CAD downloaded by web browser client
Model is directly used in various CAD versions, improves the practicality of online browse device system.
Further, the online browse device system in step 6) includes Flash clients, the webserver, network moulding clothes
Business device, web browser client and OpenGL display modules, Flash clients connection webserver port, network service
Device and network moulding server are shown by network connection web browser client, web browser client connection OpenGL
Show module, by the way that ACIS model discretizations, extraction point-line-surface information are simultaneously stored in an array in certain sequence, then should
Array is transmitted to OpenGL display modules, and OpenGL display modules can rebuild model according to these point-line-surface information, make
Flash finished product files SWF shows apparent, reduces the distortion of image, the change of aberration and the change of size.
Further, authentication module, HTTP request module and request processing module, identity are provided with the webserver
Authentication module and HTTP request module difference connection request processing module, user enter the webserver by Flash clients
HTTP request module, and online browse device system is logged in after authentication module is verified, facilitates user to upload or download CAD
Drawing, while CAD diagram paper can be directly directly read on web browser, realize that distributed collaborative operates.
Further, network moulding server include ACIS-OpenGL bridges, model management module, moulding land parcel change trace module,
ACIS moulding devices and ACIS discretizers, model management module connect respectively ACIS-OpenGL bridges, moulding land parcel change trace module and
ACIS moulding devices, moulding land parcel change trace module connection ACIS moulding devices, ACIS moulding devices connection ACIS discretizers, ACIS discretizers
Connect ACIS-OpenGL bridges.
Further, web browser client includes socket, mathematical tool storehouse, graphical tool storehouse, geometry kernel library
With ActiveX GUI modules, graphical tool storehouse connects mathematical tool storehouse, geometry kernel library and ActiveX GUI modules respectively, number
Learn tool storage room and connect geometry kernel library and ActiveX GUI modules, geometry kernel library connection ActiveX GUI modules respectively.
The present invention is by adopting the above-described technical solution, have the advantages that：
The online browse method of the present invention can be not only avoided in CAD diagram paper downloading process, because data flow is excessively huge
Cause client not respond to for a long time greatly, and CAD model data can be obtained from the webserver at any time as needed
To update in the client；It can be saved in the case where being fitted without CAD software directly by real-time performance online browse
The time of download, while selective download can be carried out according to being actually needed, reduce the occupancy of hard drive space；It is clear by downloading
The dynamic interaction between web browser client and the webserver can be achieved in device plug-in unit of looking at, and realizes strange land on-time model
Design；The conversion between different CAD versions is avoided simultaneously, makes the CAD model by web browser client download direct
For various CAD versions, the practicality of online browse device system is improved.
