The document discusses DocdokuPLM, a solution for managing product lifecycle using web technologies, targeting CAD designers with capabilities to handle various file formats and synchronization through a cross-platform application built on Node.js and WebKit. It outlines features such as a command line interface, 3D file previews, and the challenges associated with developing plugins for multiple CAD platforms. The presentation highlights the advantages of using modern web technologies while addressing potential drawbacks like increased resource requirements.

- 2. We are DocDoku 2 We help industrial organizations digitize their business Based in France ● Toulouse ● Paris Committed to the Open Source, we make DocDokuPLM: ● https://github.com/docdoku/docdoku-plm ● Twitter: @docdoku #PLM #HTML5 #Java #BigData #WebGL #IoT #Industry
- 3. About me 3 Tech experience ● 10 years in Web Technologies ● JavaScript developer ● Java EE developer Morgan Guimard ● DocDokuPLM dev leader ● Technical trainer
- 4. Agenda 4 1 – Introduction to Product Lifecycle Management 2 – Working with CAD files 3 - Our cross-platform solution
- 5. 1 - Introduction to Product Lifecycle Management
- 6. 6 Manages the entire lifecycle of a product from its conception to its disposal. Integrates people, data, processes and business systems and provides a product information backbone. Product Lifecycle Management
- 7. PBS? 7 Product Breakdown Structure A hierarchical listing of assemblies and components, and the quantities there-of, necessary to produce a final product
- 8. Parts 8 Each node of a PBS is a part Stores every information of a component, as its name, custom attributes, and its geometry file. The part number is its identifier. You may find the same part at multiple PBS levels. V54S3434RTX
- 9. Assembly / Leaf 9 ● Assembly nodes stores the structure informations ● Leaves stores the geometry ● Assemblies and leaves are both considered as parts Example: An office desk
- 10. Everything is tracked 10 ● Through Check-in / Check-out mechanism ● Iteration (1, 2, 3...) and Revision (A, B, C...) Example: Part 100 A.3 A is the revision, 3 is the iteration and A.3 is the version ● Iteration = minor changes ● Revision = major ones
- 11. 2 – Working with CAD files
- 12. Working with CAD files 12 ● Our target: CAD designers ● They are editing lot of files / large files Check in / Check out ● Those files need to be synchronized on a server ● Collaborative work is a main topic
- 13. Standard formats ? 13 Some formats are standard ● STEP, IFC, OBJ, … And some other formats are not standard ● SLDPRT, CATPART, … We're trying to convert any format, even if not standard
- 14. CAD files content 14 Depends on the format, can contains ● Geometry only ● Structure only ● Both Managed server side with DocDokuPLM server ● Converting many formats to a WebGL format ● Extracting the structure from CAD files and creating the PBS ● May require proprietary SDK to parse some none standard formats
- 15. Multiple editors 15 Many edition tools / platforms ● Windows - Mac OS X - Linux ● AutoCAD, SolidWorks, CATIA, BIM Editor ... ● Developing a plugin for all of them isn't realistic ● Should also be maintained for every software update
- 16. How can we help every CAD designer ? 16 Editor plugins ? ● Not realistic: too many editors, versions, languages Operating system integration ? ● Would be a great solution, but requires more than a single code base The easiest way for us is a cross platform application
- 17. 3 – Our cross platform solution
- 18. Command line interface 18 Fits for most advanced users... ● Scriptable ● Lightweight ● Easy to use ● Check in / Check out and synchronize files from command line with a single command ● ...but lacks a graphical user interface to easily make bulk operations $ dplm checkin some-part-number
- 19. Choosing a cross-platform technology 19 Native ? Web based ? What do we need ? ● Read and write the user's FileSystem ● Be able to interact with our JSON WebServices ● Interact with our CLI ● Have a responsive design for each display ● 3D preview
- 20. Node Webkit 20 Just a nutshell ... ● Wrapping NodeJS and a Webkit browser ● Let's keep a standard API: HTML5 ● And let's use NodeJS low level API
- 21. NodeJS brings us ... 21 … exactly what we need ● Ability to walk the user's FileSystem to discover CAD files ● Read CAD files contents to display them in a 3D preview ● An API to interact with our CLI (Directly in java or bash) ● FileSystem watchers to detect any change made on a file ● An easy way to work with JSON objects
- 22. Webkit browser 22 Helps us to : ● Create a responsive design ● Keep a single code base for each platform ● Allow HTTP connections and easy JSON parsing ● Load 3D file with WebGL technology for a live preview
- 23. Pros and cons of this choice 23 We like... ● One code base, and code reuse ● Standard API ● Fast development process ● Latest web technologies can be used ● Easy to package We don't like so much… ● App size (must embed Webkit and NodeJs) ● Requires more RAM and CPU ● Hard to mimic the OS look and feel ● May have bugs for NodeWebkit (notification, file system changes)
- 24. Our web based solution 24 DocDokuDPLM ● Built with NodeWebkit ● Using AngularJS as the main framework ● Using NodeJS API
- 25. Architecture 25 User's desktop DocDokuDPLM APP DocDokuCLINodeJS Webkit + AngularJS DocDokuPLM server FSCAD editor
- 26. Remote and local navigation 26 ● Allows the designer to browse remote and local folders
- 27. File change detection 27 ● Allows the designer quickly see which files are out of sync ● Green tick icon means synchronized ● Orange cloud icon means modified
- 28. Recursive download 28 ● Allows the designer to check out / download a whole structure within a single action ● Select existing baseline
- 29. Synchronizing a whole folder 29 ● Allows the designer to check in / upload a whole folder
- 30. 3D preview 30 ● Allows the designers to see their files in 3D before uploading them ● The same 3D engine is used in the DocDokuPLM server
- 31. To come soon 31 We'd like to bring the following features to our solution ● Desktop notifications (synchronization done, etc…) ● Better errors handling ● Shortcuts to open a part in the user's favorite editor from our app ● SMART check-in order when pushing many files in a single operation ● ...
