Find custom point coordinates with Forge - reactjs

Question

I work with Autodesk Forge (node.js, javascript (worked with it a little), React (completely new !)).
I have a rectangle 3D object. At each corner is a point with real world coordinates (lat, lon, z).
These coordinates can be displayed with the property panel in the viewer.
I want to access them from the code, but I cannot find them anywhere.
At first, I thought they would be at :
window.NOP_VIEWER.model.getData().metadata
but nothing !
Here is a picture of what I can see in the viewer. Since I can see them in the property panel, I should be able to access them !
I tried to use this :
window.NOP_VIEWER.model.getBulkProperties('1',
function(properties){console.log(properties);},
function(error){console.log(error);})
It returns an amazingly long list of field names (if think that's it).
When I try to put it in a variable it returns 'undefined'. So I cannot access what is inside anyway.
Also tried getProperties() but I think I did not write it in the right way, it doesn't work either.
I also tried som GET request to find the object properties, but all I got was this :
{
"data": {
"type": "objects",
"objects": [
{
"objectid": 1,
"name": "Model",
"objects": [
{
"objectid": 2691,
"name": "Sols",
"objects": [
{
"objectid": 2692,
"name": "Sol",
"objects": [
{
"objectid": 2693,
"name": "Dalle en béton - 250 mm",
"objects": [
{
"objectid": 2694,
"name": "Sol [236041]"
}
]
}
]
}
]
},
{
"objectid": 2711,
"name": "Modèles génériques",
"objects": [
{
"objectid": 2712,
"name": "Point_Georeferencement",
"objects": [
{
"objectid": 2713,
"name": "Point_Georeferencement",
"objects": [
{
"objectid": 2714,
"name": "Point_Georeferencement [236831]"
},
{
"objectid": 2715,
"name": "Point_Georeferencement [236836]"
},
{
"objectid": 2716,
"name": "Point_Georeferencement [236843]"
},
{
"objectid": 2717,
"name": "Point_Georeferencement [236846]"
}
]
}
]
}
]
}
]
}
]
}
}
But I cannot find a way to access the points' names or their values !
Can anyone help with this, please ?

NOP_VIEWER is a global variable to access the current Viewer. From that you can call:
.getProperties(): this requires 1 dbId, an easy way to try it is with:
NOP_VIEWER.addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT, function (e) {
e.dbIdArray.forEach(function (dbId) {
NOP_VIEWER.getProperty(dbId, function (props) {
console.log(props)
})
})
});
.model.getBulkProperties(): this received an array of elements and just return the properties you specify:
NOP_VIEWER.addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT, function (e) {
viewer.model.getBulkProperties(e.dbIdArray, ['RefX', 'RefY'], function (elements) {
elements.forEach(function(element){
console.log(element);
})
})
});
And you may also combine it with .search() (see here) or by enumerating leaf nodes.
