About Me

Jaime Rosales

Developer Evangelist at Autodesk

@AfroJme

Photoshop/Illustrator for visual designers

AutoCAD for interior designers

Rhino/Solidworks/Fusion for industrial designer

Revit for architects

Traditionally

The designer makes up a design

they send it over to their client

client needs to download a software to view the file

Outputs are proprietary formats

Universal formats out there

The problem?

  • Extremely lossy
  • Often lose meta data like quantity, width, height
  • Rendered images and pdf are 3D into 2D

WebGL

JavaScript API that lets browsers render 3D

It's not a W3C standard...

but every browser supports it

It's a difficult technology to master

Autodesk came out with a 3D/2D viewer...

Upload your CAD file

REST API

View on a browser

JavaScript API

It's free!

Would you rather see this on your e-commerce website..

or this?

Client-Side

JavaScript API

On your page

Reference the following JavaScript Libraries:

<link rel="stylesheet" href="https://viewing.api.autodesk.com/viewingservice/v1/viewers/style.css" type="text/css">
                            <script src="https://viewing.api.autodesk.com/viewingservice/v1/viewers/viewer3D.min.js"></script>

Create a div with id "viewer"

<div id="viewer"></div>

Initialize with JavaScript

function initialize() {
                var options = {
                'document' : 'urn:(Your own URN)',
                'env':'AutodeskProduction',
                'getAccessToken': getToken,
                'refreshToken': getToken,
                };
                var viewerElement = document.
                    getElementById('viewer');
                var viewer = new Autodesk.
                    Viewing.Viewer3D(viewerElement, {});

                Autodesk.Viewing.Initializer(options,function() {
                viewer.initialize();
                loadDocument(viewer, options.document);
                });
                }

token

function getToken() {
                            return "GX6OONHlQ9qoVaCSmBqJvqPFUT5i";
                            }

You should write your own token service.

loadDocument

function loadDocument(viewer, documentId) {
                    // Find the first 3d geometry and load that.
                    Autodesk.Viewing.Document.load(documentId,
                    function(doc) {
                    var geometryItems = [];
                    geometryItems = Autodesk.Viewing.Document.
                    getSubItemsWithProperties(doc.getRootItem(), {
                    'type' : 'geometry',
                    'role' : '3d'
                    }, true);

                    if (geometryItems.length > 0) {
                     viewer.load(doc.
                        getViewablePath(geometryItems[0]));
                    }
                    }, function(errorMsg) {// onErrorCallback
                    alert("Load Error: " + errorMsg);
                    });
                    }
