© 2012 Autodesk The Confluence of AutoCAD® Mobile, Desktop, and the Cloud Albert Szilvasy Software Architect, AutoCAD Engineering Team

© 2012 Autodesk Summary  This is a developer oriented presentation  An overview of how the technology landscape is changing  How we are evolving AutoCAD to fit into this landscape  Some future looking content  My guesses are educated but future is uncertain  The future is not static: please provide feedback both positive and negative

© 2012 Autodesk Agenda  State of the art in  Cloud  Client device (phone, tablet, laptop, desktop)  Browser  Evolution of the desktop application  Office 2013/Office 365  How is AutoCAD evolving?  How can developers prepare?

© 2012 Autodesk Cloud  Heavily overloaded term  From strictly technical: on-demand computing infrastructure …  To anything that you do with a connected application  How does it matter to my application?  Storage  Compute  Data and Services from others  Connectivity

© 2012 Autodesk Cloud providers Rent a virtual machine Sophisticated services Database as a service Identity directory Notifications Autoscaling Etc.

© 2012 Autodesk Cloud storage  For an application there are 2 aspects: 1. Storing customer data in the cloud  Drawing files  Other data (e.g. comments) 2. Acting on the customer data already in the cloud  A360  Skydrive, Gdrive, DropBox, Office 365  APIs to access data are important

© 2012 Autodesk Cloud Compute  Amazon started with allowing you to rent a virtual machine  Maximum control and responsibility  Easiest to migrate legacy server applications  Azure introduced this capability recently due to it popularity  The execution environment has become more managed  Amazon Elastic Beanstalk  Azure Cloud Services  Google AppEngine  More software readily accessible as virtual machine image  AWS marketplace AWS marketplace  Azure VM images Azure VM images

© 2012 Autodesk Cloud Data and Services  Applications (client or cloud) can access a vast array of data online  Machine friendly presentation  Lot of XML/JSON-based formats  Bing/Google/Nokia maps  Azure Data Marketplace Azure Data Marketplace  OData format is widely used OData  Every major website exposes some level of programmability  Facebook, Twitter, Google (+, apps, search), Microsoft (messenger, skydrive, search)

© 2012 Autodesk Cloud Connectivity  Client applications can rely on inexpensive servers  No upfront investment, easy to scale  E.g. Windows Intune (use the cloud to manage PCs)  Interesting pattern  Most work happens on the client  Requires minimal cloud storage or compute  Still provides mobile, browser access  Virtual Private Cloud  Rented servers are isolated from internet  Connect to on premises network via encrypted channel (vpn)

© 2012 Autodesk Client Devices  Trends  Desktops are getting more parallel (6-8 core CPUs)  The difference between laptop and tablet is disappearing (touch screens)  Software stack unification  iOS/Android on tablet and phone  Windows on tablet, phone and desktop  Sandboxed execution  Apps are purchases from Store and run with well understood rights  More apps each with limited, focused function  Challenge for developers  Support multiple operating systems  Support parallelism  Break down your large application into smaller apps

© 2012 Autodesk Browser  The virtual machine that works across all OS-es and device types  One programming language: Javascript, becoming an intermediate language  Google GWT, Dart Google GWTDart  Microsoft Typescript Microsoft Typescript  HTML as a UI framework  2D and 3D graphics  Canvas and WebGL  More device access  Local storage, sensors

© 2012 Autodesk Office 2013/Office 365  The most widely used desktop application suit  Historically many parallels with AutoCAD  Large C++ code base  Rich client programmability (vba,.net)  Large 3 rd party developer community  Similar UI elements (e.g. ribbon, task panes)  No reason to believe the future will be very different  Looking at Office today may inform the future of AutoCAD and vice versa

© 2012 Autodesk Office 2013 vs. AutoCAD 2013  Sign in with Microsoft account  Save/Open from SkyDrive, SharePoint  Browser-based viewing/editing in Office Web Apps Office Web Apps  Apps for Office: Javascript/HTML extensibility  Server-side: Word, Excel, PowerPoint services in Sharepoint  Sign in with Autodesk account  Save/Open from A360, Buzzsaw  Browser-based viewing/editing in AutoCAD WS  ?

© 2012 Autodesk Apps for Office  A webpage displayed inside Excel, Outlook etc.  The webpage is hosted on remote server, it can be updated without having to install anything on the client  The only thing that needs to be installed is an xml file  The webpage can access the host app via JavaScriptvia JavaScript  This is allows the webpage to use the power of the Office app  HTML/Javascript is portable  The same app can work in the desktop or web version!  Mobile can also work but the form factor does not lend itself very well to extensions (small screen, tricky to get right)

© 2012 Autodesk Demo: Creating an App for Outlook

© 2012 Autodesk Apps for Office cont.  Servers to host webpages for the app  Provided by Microsoft – simple no need for additional accounts, infrastructure  Provided by developer – very flexible but requires more work  Office Store to sell your application Office Store  Users take less risk since the app is just a webpage (sandboxed by the browser)

© 2012 Autodesk AutoCAD Futures  What happens if AutoCAD follows a similar evolutionary path as Office?  Apps for AutoCAD – JavaScript/HTML extensibility  It is already happening: Design Feed in AutoCAD WS  AutoCAD services on the server – Process DWG files on the server AutoCAD Add-in Mobile/Browser app AutoCAD Add-in Web Site

© 2012 Autodesk Apps for AutoCAD  JavaScript/HTML rendering is readily available in open source  Chromium, Chromium Embedded ChromiumChromium Embedded  Inject our own functions into the Javascript context Acweb.dll (.net) AutoCAD CefSharp.dll (.net/c++) HTML/Javascript Chromium (C++)

© 2012 Autodesk Demo: Javascript/HTML integration in a AutoCAD

© 2012 Autodesk How developers can prepare?  Learn HTML/Javascript/CSS  Learn to build websites  ASP.NET or another stack  Building Apps for Office is a good way to practice

© 2012 Autodesk Server friendly components  The economy of the cloud comes from maximum resource utilization  Host as many task as possible on a given hardware  Running the entire AutoCAD with UI is expensive  nobody is there to see it, interact with it  Need components that are server friendly  RealDWG = DWG DOM  AutoCAD Core Engine = Real DWG +

© 2012 Autodesk Exposing AcCoreConsole.exe as a service  It has not been done. How would we do it?  AcCoreConsole.exe /i /s  Inputs  Uploaded  Service to HTTP/GET from a web address  Outputs  Downloaded  Service to HTTP/PUT,POST to a web address  Script  Custom commands (autoloader package)

© 2012 Autodesk How can developers prepare?  Start building CRX applications  It is like an ARX application but  C++  Don’t link acad.lib .NET  Don’t reference acmgd.dll  Lisp  Don’t use vla, vlax  Learn HTTP/REST  Live API Live API  Google Apps API Google Apps API

© 2012 Autodesk Local File Server AutoCAD Core Engine Service Upside down Cloud Web Site Mobile/Browser App AutoCAD Core Engine Service AutoCAD Core Engine Service AutoCAD Core Engine Service

© 2012 Autodesk Upside Down Cloud  Use the computers on the local network  To process dwg files, extract or imprint data  Use the computers in the datacenter  To coordinate and manage the local workstations and their “jobs”  Store metadata  Interact with the users on mobile device, browser  Original design data never leaves the premises.  Service is cheap to provide because all heavy duty computation is done on hardware that is paid for.  You can do it now. AutoCAD 2013 ships all you will need.

© 2012 Autodesk Summary  Desktop applications will need to be more connected  Javascript/HTML is the lingua franca of the client. Learn it.  Websites will need to be more programmable  REST is the lingua franca of the programmability. Learn it.  The difference between desktop, cloud, mobile is rapidly disappearing  Difficult to predict the future.
