The Properties window does not populate any properties even though the 2D view has properties info for the selected room
Here is the function that loads the model. what am I missing?
function loadModel() {
var initialViewable = viewables[indexViewable];
var svfUrl = lmvDoc.getViewablePath(initialViewable);
var modelOptions = {
sharedPropertyDbPath: lmvDoc.getFullPath(lmvDoc.getRoot().findPropertyDbPath())
};
viewer.loadModel(svfUrl, modelOptions, onLoadModelSuccess, onLoadModelError);
}
One line missing in your code, please try the following instead:
var sharedDbPath = initialViewable.findPropertyDbPath();
sharedDbPath = lmvDoc.getFullPath( sharedDbPath );
var modelOptions = {
sharedPropertyDbPath: sharedDbPath
};
However, you should not need to specify the sharedPropertyDbPath manually now. You can take advantage of the Viewer3D#loadDocumentNode to load the model directly. It will automatically determine the path for you. (started from v7 viewer)
const initialViewable = viewables[0];
viewer.loadDocumentNode( lmvDoc, initialViewable, loadOptions )
.then( onLoadModelSuccess )
.catch( onLoadModelError );

I have a simple forge app to view 3d models. At first, I initiated the forge viewer with GuiViewer3D class but then wanted to implement AggregatedView instead.
My problem is that AggregatedView shows the model correctly but it shows it as being "stitched" together. Whereas, if I use GuiViewer3D or Viewer3D, the model looks smooth and clean.
I have looked into the globalOffset but in any solution, the globalOffset is the same, and hence should not be the cause here.
This is how the model should look like (GuiViewer3D)
But this is how it looks like instea using AggregatedView
I am not quite sure what the issue here. I am using an .fbx file as the source of 3d model.
This the code of AggregatedView()
var view = new Autodesk.Viewing.AggregatedView();
function launchViewer(urn) {
var options = {
env: 'AutodeskProduction',
getAccessToken: getForgeToken
};
Autodesk.Viewing.Initializer(options, () => {
var htmlDiv = document.getElementById('forgeViewer');
view.init(htmlDiv, options);
var documentId = 'urn:' + urn;
view.unloadAll();
Autodesk.Viewing.Document.load(documentId, onDocumentLoadSuccess, onDocumentLoadFailure);
});
}
function onDocumentLoadSuccess(doc) {
var nodes = doc.getRoot().search({ role:'3d', type: 'geometry' });
console.log(nodes);
view.setNodes(nodes[0]);
}
function onDocumentLoadFailure(viewErrorCode, viewErrorMsg) {
console.error('onDocumentLoadFailure() - errorCode:' + viewErrorCode + '\n- errorMessage:' + viewErrorMsg);
}
function getForgeToken(callback) {
fetch('/api/forge/oauth/token').then(res => {
res.json().then(data => {
callback(data.access_token, data.expires_in);
});
});
}
Many thanks in advance!
UPDATE:
After setting the global offset to (0,0,0), the geometry still looks "Stitched" together rather than smooth.
The pivot point is not the global offset. Please use viewer.getAllModels().map( model => model.getGlobalOffset() ) to check that instead. For AggreagateView, you can get the viewer instance via view.viewer;
In addition, AggreagateView loads models in the shared coordinate (applyRefPoint: true), so your model might be far away from the viewer's origin. Could you try this to see if it helps?
const options3d = {
getCustomLoadOptions: (bubble, data) => {
console.log(bubble, data);
return {
applyRefPoint: false //!<<< Disable Share Coordinate
// globalOffset: new THREE.Vector3( 543.0811920166016, 9.154923574611564, -1442.591747316564 ) //!<<< uncomment this to specify your globalOffset, but you need to include `applyRefPoint: false` above together.
// createWireframe: false
};
}
};
view.init(viewerDiv, options3d);
Good day,
I am using the latest Autodesk forge viewer and I am trying to take a screenshot that also renders my markups. Right now my code takes a screenshot without any markups. Below is my viewer code. I am loading markups Core and markups Gui extensions. Notice the "takeSnapshot(viewer)" function inside onDocumentLoadSuccess(viewerDocument). The function is defined right before the initializer function.
function takeSnapshot(target){
$('#snipViewer').click( () => {
target.getScreenShot(1600, 920, (blobURL) => {
let snip = blobURL;
$('#sniplink').attr("href", snip);
$('#sniplink').html('Not Empty');
$('#sniplink').css({"background-image": `url(${blobURL})`});
});
});
}
//Autodesk Viewer Code
instance.data.showViewer = function showViewer(viewerAccessToken, viewerUrn){
localStorage.setItem("viewerAccessTokentoken", viewerAccessToken);
localStorage.setItem("viewerUrn", viewerUrn);
var viewer;
var options = {
env: 'AutodeskProduction',
api: 'derivativeV2',
getAccessToken: function(onTokenReady) {
var token = viewerAccessToken;
var timeInSeconds = 3600;
onTokenReady(token, timeInSeconds);
}
};
Autodesk.Viewing.Initializer(options, function() {
let htmlDiv = document.getElementById('forgeViewer');
viewer = new Autodesk.Viewing.GuiViewer3D(htmlDiv);
let startedCode = viewer.start();
viewer.setTheme("light-theme");
viewer.loadExtension("Autodesk.CustomDocumentBrowser").then(() => {
viewer.loadExtension("Autodesk.Viewing.MarkupsCore");
viewer.loadExtension("Autodesk.Viewing.MarkupsGui");
});
if (startedCode > 0) {
console.error('Failed to create a Viewer: WebGL not supported.');
$("#loadingStatus").html("Failed to create a Viewer: WebGL not supported.");
return;
}
console.log('Initialization complete, loading a model next...');
});
var documentId = `urn:` + viewerUrn;
var derivativeId = `urn:` + instance.derivativeUrn;
Autodesk.Viewing.Document.load(documentId, onDocumentLoadSuccess, onDocumentLoadFailure);
function onDocumentLoadSuccess(viewerDocument) {
var defaultModel = viewerDocument.getRoot().getDefaultGeometry();
viewer.loadDocumentNode(viewerDocument, defaultModel);

I have already read this article: https://forge.autodesk.com/blog/screenshot-markups
I have tried doing this method but the instructions are very unclear for me. <div style="width:49vw; height:100vh;display:inline-block;"><canvas id="snapshot" style="position:absolute;"></canvas><button onclick="snaphot();" style="position:absolute;">Snapshot!</button></div>
What is the canvas element here for? Am I supposed to renderToCanvas() when I load the markups extension inside the initialize function or in my screenshot function? Is there some way I can implement the renderToCanvas() without changing too much of what I already am using here? I am not an expert with the viewer API so please if you could help me it would be very much appreciated, I am a beginner please don't skip many steps.
Thank you very much!
Here's a bit more simplified logic for generating screenshots with markups in Forge Viewer, with a bit more explanation on why it needs to be done this way below:
function getViewerScreenshot(viewer) {
return new Promise(function (resolve, reject) {
const screenshot = new Image();
screenshot.onload = () => resolve(screenshot);
screenshot.onerror = err => reject(err);
viewer.getScreenShot(viewer.container.clientWidth, viewer.container.clientHeight, function (blobURL) {
screenshot.src = blobURL;
});
});
}
function addMarkupsToScreenshot(viewer, screenshot) {
return new Promise(function (resolve, reject) {
const markupCoreExt = viewer.getExtension('Autodesk.Viewing.MarkupsCore');
const canvas = document.createElement('canvas');
canvas.width = viewer.container.clientWidth;
canvas.height = viewer.container.clientHeight;
const context = canvas.getContext('2d');
context.clearRect(0, 0, canvas.width, canvas.height);
context.drawImage(screenshot, 0, 0, canvas.width, canvas.height);
markupCoreExt.renderToCanvas(context, function () {
resolve(canvas);
});
});
}
const screenshot = await getViewerScreenshot(viewer);
const canvas = await addMarkupsToScreenshot(viewer, screenshot);
const link = document.createElement('a');
link.href = canvas.toDataURL();
link.download = 'screenshot.png';
link.click();
Basically, the markups extension can only render its markups (and not the underlying 2D/3D scene) into an existing <canvas> element. That's why this is a multi-step process:
You render the underlying 2D/3D scene using viewer.getScreenShot, getting a blob URL that contains the screenshot image data
You create a new <canvas> element
You insert the screenshot into the canvas (in this case we create a new Image instance and render it into the canvas using context.drawImage)
You call the extension's renderToCanvas that will render the markups in the canvas on top of the screenshot image
I have been using following .impl methods in V6*
viewerApp.getCurrentViewer().impl.invalidate
viewerApp.getCurrentViewer().impl.matman()._materials
How to proceed with V7*
Thank you
EDIT :
var options = {
env: 'AutodeskProduction',
api: 'derivativeV2',
getAccessToken: function(onTokenReady) {
var token = accessToken;
var timeInSeconds = 3600;
onTokenReady(token, timeInSeconds);
}
};
var documentId = "urn:" + urn;
Autodesk.Viewing.Initializer(options, function() {
var htmlDiv = document.getElementById('forgeViewer');
viewer = new Autodesk.Viewing.GuiViewer3D(htmlDiv);
var startedCode = viewer.start();
if (startedCode > 0) {
console.error('Failed to create a Viewer: WebGL not supported.');
return;
}
console.log('Initialization complete, loading a model next...');
Autodesk.Viewing.Document.load(documentId, onDocumentLoadSuccess, onDocumentLoadFailure);
});
...
Then I'm using impl methods as below ..
var mats = viewer.impl.matman()._materials;
But I still get the error
Cannot read property 'impl' of null
not sure why but may be my global viewer variable is null , any idea why this is happening or what have i done wrong.
Anything under the impl is typically considered internal implementation, and as such should not be relied on in production code. With that said, the impl property is still available, and if needed, you can use it in Forge Viewer version 7.* like so:
const viewer = new Autodesk.Viewing.GuiViewer3D(...);
viewer.impl.invalidate();
viewer.impl.matman();
I have tried to start the model browser with all nodes collapsed when loading several aggregated models, but it do no collapse all nodes. Is there any way to do this?
Try the code below on these model: https://wallabyway.github.io/federatedmodels-v7/
var ext = NOP_VIEWER.getExtension('Autodesk.ModelStructure')
ext._modelstructure.options.startCollapsed = true
Try to use this one instead. The ModelStructralPanel will read options in its constructor only.
var viewer = new Autodesk.Viewing.GuiViewer3D(container, {startCollapsed: true});
var ext = viewer.getExtension('Autodesk.ModelStructure');
// or
// viewer.unloadExtension('Autodesk.ModelStructure');
// var ext = await viewer.loadExtension('Autodesk.ModelStructure', {startCollapsed: true});
Workaround:
Add this code snippet before opening the modelstructure panel.
var ext = viewer.getExtension('Autodesk.ModelStructure');
ext._modelstructure.addVisibilityListener( show => {
if( show && (!ext._modelstructure.uiCreated) ) {
ext._modelstructure.tree.delegates.forEach( d => ext._modelstructure.tree.setAllCollapsed( d, true ) )
}
});
When creating the viewer, pass the following option to it:
var viewer = new Autodesk.Viewing.GuiViewer3D(container, {modelBrowserStartCollapsed: true});
It should cascade until reaching the model browser.
Background
The option "modelBrowserStartCollapsed" is passed on from the Viewer3D constructor up until the ModelStructureExtension, where it changes name to "startCollapsed" as it is passed to the ViewerModelStructurePanel.
proto.restoreDefaultPanel = function () {
var config = this.viewer.config;
var options = {
docStructureConfig: config.docStructureConfig,
hideSearch: (0, _src_compat__WEBPACK_IMPORTED_MODULE_2__.isMobileDevice)(),
excludeRoot: config.modelBrowserExcludeRoot,
startCollapsed: config.modelBrowserStartCollapsed // HERE
};
var modelTitle = config.defaultModelStructureTitle || 'Browser';
var panelInstance = new _src_gui_ViewerModelStructurePanel__WEBPACK_IMPORTED_MODULE_1__.ViewerModelStructurePanel(_objectSpread(_objectSpread({},
options),
(0, _src_gui_ViewerModelStructurePanel__WEBPACK_IMPORTED_MODULE_1__.generateDefaultViewerHandlerOptions)(this.viewer)),
modelTitle);
this.setModelStructurePanel(panelInstance);
};
The source for ViewerModelStructurePanel shows that it takes the option "startCollapsed" as stated, among other options.
function ViewerModelStructurePanel(viewer, userTitle, ops) {
...
options.startCollapsed = options.startCollapsed !== undefined ? options.startCollapsed : false;
I am struggling to view a pdf in the forge viewer. All other drawings .rvt .dwg .dxf .nwd are showing without any issue.
Initially I received a error
Cannot read property 'loadFromZip' of undefined
Have managed to evade this by adding "loadOptions" into the modeloptions I send through to the viewer. But now I get a error 6 back from the viewer which is a server error. Please if someone could advise what to do.
loadModel() {
var initialViewable = viewables[indexViewable];
var svfUrl = lmvDoc.getViewablePath(initialViewable);
var modelOptions = {
sharedPropertyDbPath: lmvDoc.getPropertyDbPath(),
loadOptions: {}
};
viewer.loadModel(
svfUrl,
modelOptions,
this.onLoadModelSuccess,
this.onLoadModelError
);
}
Thanks in advance
You have to use ViewingApplication rather than Viewer3D or GuiViewer3D to initialize your viewer to view PDF files since there are some additional configuration values for PDF set up by the ViewingApplication automatically.
Also refer to:
Forge Viewer fails to dispaly PDF's
=== Example for passing configs to Viewer instance via ViewingApplication ===
//--- Method 1:
var viewerConfigs = {
extensions: ['MyAwesomeExtension'],
extOpts: {
MyAwesomeExtension: {
buttonColor: 'red'
}
}
};
var viewerApp = new Autodesk.Viewing.ViewingApplication('MyViewerDiv');
viewerApp.registerViewer(viewerApp.k3D, Autodesk.Viewing.Private.GuiViewer3D, viewerConfigs);
// In the constructor of the MyAwesomeExtension
class MyAwesomeExtension extends Autodesk.Viewing.Extension {
constructor( viewer, options ) {
super( viewer, options );
// your options here
const opts = options.extOpts.MyAwesomeExtension;
}
}
//--- Method 2:
// After model was loadded,
var viewer = viewerApp.getCurrentViewer();
var extOpts = {
opt1: true
};
viewer.loadExtension( 'Autodesk.ADN.MyExtension', extOpts );
