Process of P3DM products plan, data reachs the administrative function of graph archives

State committee of science and technology puts forward 72 　 the enterprise of before 2000 95% , designing institute place throws drawing board, the development of CAD software product through a few years, promotion and application, the application of partial area and company in technology of personal computer CAD, especially the use respect of software of 2 dimension CAD, obtained delectable positive result, basically threw drawing board, make plot, job giving a picture is changed more scientificly, standardization, standardization, conform with international. Meanwhile, we also should see, the function of software of 2 dimension CAD is very finite still, module is not perfect still, far the computational advantage that did not produce personal computer, so, the application of technology of personal computer CAD should develop to deeper administrative levels. Products of 2 CAD of dimension personal computer classify 　 1.

Graphical platform software: Be like: AutoCAD, MicroStation. These software and specific application have nothing to do, complete main graphical operation, and open sex is very good. Because be the popular software on the world, its graph pattern is more general, format of each version graph can well compatible. 2.

The software of CAD of 2 dimension machinery that home develops completely independently: Because be developed for mechanical design technically, so software is in it is better to accord with international, practical aspect; But the advanced sex of software, compositive sex, open sex, support that sets external still have bigger difference with foreign software, especially software whether continuance goes down, waiting with the compatibility of popular software on the world is the key that decides this kind of software lives. 3.

Be based on the appreciation software that AutoCAD platform develops: The advantage of before this kinds of software was absorbed two kinds of software, development is rapidder. This kind of software divides again for two administrative levels: (1) had the blueprint that accords with GB, national condition only setting, tag, symbolic library, graph library, parameter changes the function such as design, editor, design personnel is used easily, the plot, speed that become a figure had rise substantially. This kind of software is a standard " throw drawing board " software. (2) go up in afore-mentioned foundations, increased computation, simpler parameter to change graph library to build library tool and drawing government function. These functions are to face " design " , but practical very poor, developer and user are out of line badly. Be like drawing government function basically is " after the event " management, after plot saves file to disk, again its put in storage, input this blueprint information, divide administrative levels government, have search simply reach preview a function, preliminary if use top-down means,solved applied CAD, the graphical part of the spare parts is managed by the blueprint after assembling a technology, but process of this function and plot, design has nothing to do basically, and need repeats type message, so design personnel is used lesser or never had used, efficiency is not actually tall, not practical. The application of technology of 2 dimension CAD analyses personal computer of 2 home company, designing institute place 　 1.

Numerous enterprise, designing institute, individual is being used Chinese use AutoCAD each version software, be like: AutoCAD10, 12, 13, when 14 version, different level land did work of a few settings, development, especially big company, designing institute made graph layer, line model, the CAD cartography standard such as color, development is confined to do a few those who be badly in need of is commonly used a library, make design personnel to be able to begin the work with AutoCAD software, plot, editor, tag wait for a function to did not increase. So, a lot of enterprises, designing institute already basically " swing " drawing board, tell at drawing board plot relatively, plot speed had a few to rise, editor, revise went to the lavatory a lot of, but efficiency rises not much, compare with investment very unworthily. 2.

A few medium and small businesses, designing institute place bought the software that appreciation develops on AutoCAD 2 times, a few enterprise used own copyright software, to odd Zhang Tu the scale of paper is told, in plot, tag, the respect that become a figure is more convenient, quick, preliminary achieved throw drawing board, promote efficient goal. 3.

A few large companies, designing institute place has special demand on product development, have characteristic of oneself industry, enterprise. General plot designs systematic software to cannot satisfy their requirement, on a lot of AutoCAD 2 times development software cannot suit an user well already some settings are normative; The graph archives of type of the put in storage in the software of 2 dimension CAD on the market manages a function to also cannot make an user satisfactory. So, these large companies, designing institute still is given priority to with using AutoCAD platform software. The products plan process of 3 enterprises, designing institute place and each phase workload 　 1.

Above all, before the design work of enterprise, designing institute place begins, answer already project approving, undertake whole plans, conceive product structure, careless draw product assembles general drawing, tear open component graph, part drawing again, this is top-down design, meeting couple falls to be designed up oneself or also mix design mode sometimes. 2.

Part drawing design: Plot (contain an editor, revise) workload and dimension, symbol tag (contain an editor, revise) workload is usable next graphs express: If use top-down means, the graphical part of the spare parts by assembly drawing " dismantle a plan " and into, the time that scale graph takes up will be fewer. Accordingly, other 10%50% tags the user 40% plot were bought at present 45%20% of department of design of plot of on the market 2 dimension tags a project to set 25% plan 4 plot 10% other after 123123 all software, the scale of part drawing decreases greatly into graph time, efficiency rises. 3.

Assembly drawing design: Outside removing a logo, main job is serial number / condition of list, technology. If use means of from bottom to top, the graphical part of assembly drawing by part drawing " assemble " and into, the time that scale graph takes up won't be too much, such serial number / condition of the processing of name detailed list, technology is tagged appear very important. The workload of departmental cent is the same as part drawing basically. 4.

Project design: From the point of the angle of project, product, design process control, design is harmonious (dimension column of harmonious, caption / list data is coordinated) , the processing of list (output of collect, classification, statistic, forms for reporting statistics) , the design is summed up (file directory of design catalog, design, a few necessary forms for reporting statistics) , , call these jobs " the project is designed " . So a whole products plan, the workload of departmental cent is as follows roughly: Current, the great majority that sells on the market software of general mapping system does not support 2 dimension " the project is designed " function, these work to be able to be finished by hand only, serious obstacle of CAD efficiency and quality rise. The P3DM tool of company of the Milky way of change of 4 Tsinghua Beijing is based on afore-mentioned analysises, use ObjectARX of tool of Autodesk company newest development and advanced development language, the PCCAD7 that company of the Milky way of Tsinghua Beijing change rolls out recently.

0(is based on AutoCADR14 edition) plot of 2 dimension machinery increased P3DM to assist a tool in design management software, the meaning of P3DM is Product Design Process, Da-ta, Drawing Manager; namely management of archives of products plan process, data, graph. The object that face is design branch or design personnel, she is different from the archives of intention of style of put in storage of low before administrative levels to manage already, also manage unlike the data of company level product that crosses a branch (PDM) . The characteristic of P3DM is extremely as close together as union of process of plot, design, automatically, process of plot of real time monitoring, design, do not bring redundant add workload to design personnel, be about to archives of data of the design process of project, product, product, graph and assemble a relation organic land management rises. Of P3DM tool roll out the state that ended 2 dimension CAD systems of our country to be able to assist plot only. P3DM not only will " design " the function introduces successfully in system of 2 dimension CAD, and come to the user care all the time and look forward to for years " design administration " functional infuse in system of 2 dimension CAD. P3DM is an effective design government tool not only, she is a function designs compositive environment formidably more. Everything what the member that P3DM system solved a design encounters in products plan process manages and coordinate an issue. She has the following characteristic, can fulfil the following function: 1.

With PCCAD7.

System of 0 plot design is not had seam compositive. 2.

Comprehensive management and control design a process. Support the from above to below of the product, from bottom to top and mixture design pattern. 3.

Indication product assembles relation and component sort. 4.

Manage blueprint attribute data. Establish blueprint information automatically, be like: Name of name of position of image, filestore, file, blueprint, code name, material, amount, graph, the information such as scale. 5. Support is additional blueprint is added narrate information. 6.

Of the blueprint that finish found, open, the operation such as memory. 7.

Assemble relevant: Ranking list and information of correspondence of inferior caption column are automatic and associated. 8.

Immediate in P3DM editor revises caption column and list data. 9.

List (BOM) processing: The collect of class of the project that finish, product, classification, statistic and forms for reporting statistics. 10.

Blueprint statistic function: The statistic of the project that finish, product (blueprint page number, A4) , design catalog generate. 11.

Discharge graph function: Reach a product to the project automatically all or appoint blueprint to undertake discharging a graph, identify blueprint size, direction and scale automatically. Concentration outputs blueprint paper. 12.

Offer graph archives to govern a function: Concern through product, project, task and their clear assembly and concern logically, classification stores and manage different electronic graph archives. 13.

Offer a variety of blueprint to inquire a function, get the blueprint of need and inquiry blueprint information quickly. The place on put together is narrated, have " the project designs management (P3DM) " the PCCAD7 of the tool.

0 version technology practical, module perfects advanced, function. From plot, tag, the respect such as graph of management, statistic, platoon is all-around the work efficiency that the land improves an enterprise to design a section, achieved truly shorten products plan is periodic, raise the goal of market competition ability, to our country application of CAD of 2 dimension machinery is sure to rise extremely those who be in postpone an action.
