Get the measured value - autodesk-forge

Question

I have forge on a web page with a modal I created. The behavior of the program should be: the user presses a Button it starts the measurer tool and it gets the measurement.
However, I struggle to get the distance that have been measured and I couldn't find anything that helps online
Appreciate your help,

Answer 1

You can get the list of all measurements with this function :
const measureExtension = viewer.getExtension('Autodesk.Measure');
var measureList = measureExtension.getMeasurementList();
This will give you an array of measures that look like this :
[{
"from": "Vertex",
"to": "Vertex",
"distance": "260.7 mm",
"deltaX": "29.4 mm",
"deltaY": "14.8 mm",
"deltaZ": "258.7 mm",
"angle": "0.0 °",
"area": "NaN",
"arc": "0.0 mm",
"location": "X: 0.0 mm\nY: 0.0 mm\nZ: 0.0 mm",
"text": "",
"unitType": "mm",
"precision": 1,
"picks": [
{
"intersection": {
"x": 35.7674868316803,
"y": 35.74486039263916,
"z": 28.212904609725967
},
"modelId": 1,
"viewportIndex2d": null,
"snapNode": 14
},
{
"intersection": {
"x": 6.363343438640598,
"y": 50.51345608813477,
"z": -230.43969448657225
},
"modelId": 1,
"viewportIndex2d": null,
"snapNode": 16
}
],
"type": "Distance"
}]
Also if you want to execute something everytime a new measure has been made, you can subscribe to MEASUREMENT_COMPLETED_EVENT:
viewer.addEventListener(Autodesk.Viewing.MeasureCommon.Events.MEASUREMENT_COMPLETED_EVENT, (event)=> {
/* HERE YOUR CODE */
});
