@Konstantin-Tokarev I'm afraid no, I'm not a JS dev. The problem is that JS code I posted in the first message does not work with errors
https://cdn.3dmapping.cloud/18.1.4/javascript/orbitgt_3dm_sdk.js line
1: TypeError: a.call is not a function. (In 'a.call(this,t,e,n,r)',
'a.call' is an instance of ProxyObject)
I was able to identify that calls Array.from() and Object.assign() are missed, but maybe there are more.
