The present invention relates to a drawing sharing method for 3D printing based on the Internet and a project hosting method using such a method without downloading the drawing for 3D printing. The drawing sharing method for 3D printing of the present invention includes converting a drawing for 3D printing into a streaming file in a drawing production server, and accessing and reviewing and marking up the converted streaming file by general users, and Storing the information in a collaboration database. According to the present invention, all companies involved in the project can jointly design and review 3D printing drawings and share related information without downloading hundreds of megabytes of 3D CAD models or 2D drawings. You can share.

The present invention relates to a drawing sharing method for 3D printing based on the Internet, and more particularly, to a drawing sharing method and a method for enabling a plurality of users to collaborate on a three-dimensional model using the Internet. A project hosting method for managing the performance of a project. In modern times, due to globalization and segmentation of companies, many performers, such as client, design supervisor, and construction companies, work together to carry out a project. There is an increasing demand for implementing a collaborative work environment, such as working for a company. Due to the increasing demand of the related industry, a project hosting service providing a collaboration environment using the Internet is provided. Project hosting service refers to a service that enables all relevant companies to carry out a project to jointly design and review the drawings for 3D printing and to share related information with each other. However, the conventional project hosting service uses a method in which users access the Internet to download necessary 3D printing drawings to a computer of a related company, and then modify drawings in the downloaded state. However, such a download method requires a 3D printing drawing to be downloaded to a third party computer, so that the design drawing is leaked, and the leaked drawing can be arbitrarily processed and reused. Due to security problems with such drawings, many companies are reluctant to adopt the aforementioned download method when providing a project hosting service. In addition, due to the nature of the web browser, it is almost impossible for a plurality of users to jointly review on the Internet after downloading a large three-dimensional CAD model or a two-dimensional CAD file whose file size is several hundred megabytes. Therefore, the project hosting service using the conventional download method is applied only to two-dimensional drawings or documents having a small file size, and there is a problem that cannot be applied to three-dimensional models such as drawings for 3D printing.

In order to solve the above-mentioned problems, the present invention provides a 3D printing that enables the relevant companies performing the project to jointly design and review large 3D models or drawings and share information related to the project without downloading the 3D printing drawings. An object of the present invention is to provide a drawing sharing method. Another object of the present invention is to provide a project hosting method using the drawing sharing method.

To this end, the present invention includes a general directory for storing the downloadable 3D printing drawings, and the drawing sharing server having a drawing production server, characterized in that it includes a download prohibited directory for storing a download prohibited drawing or a 3D printing drawing. In the method, the step of uploading a drawing for 3D printing to the drawing production server using the Internet, and when uploading a drawing for 3D printing to the download prohibition directory, the uploaded drawing for the 3D printing attribute data Converting into a streaming file consisting of a base and graphic data, and those who want to modify the 3D printing drawing, accessing the drawing production server to mark up the part to review and modify the streaming file; The server collaborates on the marked up content. And a step of storing at the other base.

Hereinafter, a drawing sharing method for 3D printing according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a system for implementing a drawing sharing method for 3D printing according to the present invention. Hereinafter, with reference to FIG. 1, the structure of the said system is demonstrated.

Drawing production server 110 for implementing a drawing sharing method for 3D printing in accordance with the present invention includes a file conversion unit 112, a collaboration database unit 114 and a common directory 116, the server 110 ) Is connected to each other using a communication network, for example, the Internet and the like, the computer 100 of the drawing maker and the computer 120 of a general user who wants to modify and review drawings for 3D printing in the server.

The common directory 116 is composed of a general directory for storing downloadable 3D printing drawings and a download prohibition directory for storing non-downloadable 3D printing drawings. On the other hand, the file conversion unit 112 converts the 3D printing drawing stored in the download prohibition directory into a streaming file consisting of graphic data and attribute data. And through the collaboration database 114, the general user reviews the streaming file and stores the result.

Hereinafter, a drawing sharing method for 3D printing implemented in a system having the above-described configuration will be described in detail with reference to FIG. 2. First, in step 200, the drawing maker produces a drawing for 3D printing, and then uploads the drawing to a drawing production server using the Internet. In this case, the server provides a general directory that can be downloaded and a download prohibition directory that cannot be downloaded. Thus, the 3D printing drawings uploaded to the general directory are downloaded to the user's computer (step 210), reviewed and modified (step 212), and the modified 3D printing drawings are uploaded back to the general directory in the server ( Step 214). Meanwhile, in step 220, the 3D printing drawing stored in the download prohibition directory is converted into a streaming file consisting of attribute data and graphic data by the server and then stored again in the download prohibition directory. In this case, the 3D printing drawing is converted into a streaming file by a file converter, for example, an optimizer server. Therefore, when the user accesses the 3D printing drawing of the server using a web browser, the server displays the user's field of view. Only objects contained in are transmitted to the user's screen in the form of a stream. When the user changes the direction of time, the server transmits corresponding graphic data in a stream format again. Such a streaming method has an advantage that, compared to the download method, even if the size of the data is large, it can be immediately accessed and the security can be maintained since no data remains on the user's computer. Next, in step 222, the person who wants to review the drawing for 3D printing accesses the server using the Internet and accesses and reviews the streaming files stored in the download prohibition directory. After the review, the results are stored in a collaboration database built on the server in markup form (step 224). Subsequently, in step 226, the server may send markup data stored in the collaboration database by e-mail to people associated with the job, and may also be displayed through a web page in the server. In addition, it is also possible to convert the contents of the e-mail or the matter of delivery into voice data for transmission using a mobile phone.

Hereinafter, a project hosting method using the above-described drawing sharing method for 3D printing will be described in detail with reference to FIG. 3. First, the process of registering and setting up a project will be explained. In step 400, a customer who wants to perform a project connects to a project hosting server using the Internet, and inputs quotation request information about the project (step 402). The request for quotation includes information required by the service provider to calculate the quotation, such as project volume and period. When the customer enters the request for quotation information about the project, the contractors view the registered projects (step 412) and submit a quote (step 414). Subsequently, in step 420, the customer compares the quotations submitted by the service providers with their registration information, selects a service provider, and enters into a project execution contract.

Next, in step 422, the drawing collaboration and review software for 3D printing or a viewer or engineering software for documents not to be downloaded for security is determined, and the maximum number of users for each software is set. Next, in step 424, a public directory that can be shared among businesses related to the project is set in the server. At this time, a general directory that can be downloaded and a download prohibition directory to prohibit download are set. In step 426, all users related to the project are registered and their rights are set. At this time, each user's name, e-mail address, telephone, fax and job title can be specified. When a user is registered, the server sends a mail to the user, and the user connects to the server and his information. It is desirable to be able to record in more detail. Once the users are registered, the server classifies the users into groups and assigns rights to each group. In this case, the user is granted permissions such as view, edit, delete, update, and the like stored in each directory. As described above, the registration and setting work of the project is completed. As described above, when the registration and setting of the project for executing the project is completed, the project hosting work using the drawing sharing method for 3D printing is started. First, in step 428, the customer or each related company puts documents related to the project execution such as project specification, project execution guideline, drawings, engineering data, etc. in the public directory built in the server, wherein the file format is office Document, CAD file, or image file. Once the file is placed on the public directory, the server simultaneously distributes e-mail to the user group with the purpose and description. Next, in step 430, each user accesses the files in the public directory according to the permissions given to him and performs the project. In this case, the documents uploaded to the general directory may be downloaded to the user's computer, and then modified and reviewed according to the user's authority and then uploaded to the general directory. However, documents in the download prohibition directory can be reviewed without being downloaded to the user's computer, but cannot be modified directly by the administrator. When the document is uploaded to the download prohibition directory, the server converts the uploaded document into a streaming file consisting of attribute data and graphic data using the optimizer server and stores the document again in the download prohibition directory. Users of related companies wishing to review the document access the streaming file using the Internet, review the result, and store the result in a markup form in a collaboration database in the server. The server can then send markup data stored in the collaboration database by e-mail to users associated with the project, or display the content via a web page.
