Hello All,
We have a requirement of rendering precast models in our app. we are evaluating babylon for the same.
The precast models are in .pxml format. In future we might also support .unitechnik format.
Is this possible using babylon.js? If yes can someone pointout on the approach or method that can be used
This is not something we support by default but you could certainly create a loader for them and this would be an awesome contribution if you were willing to contribute it back 
You can have a look at our loaders to heavily find inspiration on how to create a loader in babylon.
sure i will check, i will in that case first need to understand pxml file specification
