I am a developer who's currently trying to add another button to the Autodesk Forge Viewer. I can only find one example on the Autodesk website which explains this and I feel like I would understand more through a discussion or example.
I currently have a very basic viewer, which asks for a bucket name and model then once it uploads the model it shows the model in the viewer with all the generic buttons, how do I go about inserting my own button?
Below is the viewer.html used in my basic viewer:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="https://developer.api.autodesk.com/viewingservice/v1/viewers/three.min.css"></script>
<link rel="stylesheet" href="https://developer.api.autodesk.com/viewingservice/v1/viewers/style.min.css" />
<script src="https://developer.api.autodesk.com/viewingservice/v1/viewers/viewer3D.min.js"></script>
</head>
<body onload="initialize()">
<div id="viewer" style="position:absolute; width:90%; height:90%;"></div>
<script>
function authMe () { return ('eyJhbGciOiJIUzI1NiIsImtpZCI6Imp3dF9zeW1tZXRyaWNfa2V5In0.eyJjbGllbnRfaWQiOiJJTzY5cVJGYk5kNGlVcWlnS3FnR2xzREdzSk1zQVNBYyIsImV4cCI6MTUzNjMzMDYwMiwic2NvcGUiOlsiZGF0YTpyZWFkIiwiZGF0YTp3cml0ZSIsImJ1Y2tldDpjcmVhdGUiLCJidWNrZXQ6cmVhZCJdLCJhdWQiOiJodHRwczovL2F1dG9kZXNrLmNvbS9hdWQvand0ZXhwNjAiLCJqdGkiOiJ6Q0U5R0FMOGFHNWhOdlFFSjhqeExFZDVqTjc1MXV1UjA0UENIME9mYzRRT0k5b2pkRXhyeUE1MmJwdHdsdU5XIn0.FM1P50Ldu1H1LygYXwtP77Kr3128xFZKMgoaBmtXqF0') ; }
function initialize () {
var options ={

} ;
var viewerElement =document.getElementById ('viewer') ;
//var viewer =new Autodesk.Viewing.Viewer3D (viewerElement, {}) ; / No toolbar
var viewer =new Autodesk.Viewing.Private.GuiViewer3D (viewerElement, {}) ; // With toolbar
Autodesk.Viewing.Initializer (options, function () {
viewer.initialize () ;
loadDocument (viewer, options.document) ;
}) ;
}
function loadDocument (viewer, documentId) {
// Find the first 3d geometry and load that.
Autodesk.Viewing.Document.load (
documentId,
function (doc) { // onLoadCallback
var geometryItems =[] ;
geometryItems =Autodesk.Viewing.Document.getSubItemsWithProperties (
doc.getRootItem (),
{ 'type' : 'geometry', 'role' : '3d' },
true
) ;
if ( geometryItems.length <= 0 ) {
geometryItems =Autodesk.Viewing.Document.getSubItemsWithProperties (
doc.getRootItem (),
{ 'type': 'geometry', 'role': '2d' },
true
) ;
}
if ( geometryItems.length > 0 )
viewer.load (
doc.getViewablePath (geometryItems [0])//,
//null, null, null,
//doc.acmSessionId /*session for DM*/
) ;
},
function (errorMsg) { // onErrorCallback
alert("Load Error: " + errorMsg) ;
}//,
//{
// 'oauth2AccessToken': authMe (),
// 'x-ads-acm-namespace': 'WIPDM',
// 'x-ads-acm-check-groups': 'true',

) ;
}

Here you can find an example of creating the basic skeleton we use in most of our samples to add buttons to the UI toolbar of the viewer.
