Hello, ​@couch.

Thank you for posting to the community.

Not personally, but since it’s an API format, you could try with the HTTPCaller, or if it supports the OpenAPI Specification with the OpenAPICaller.

However, we do support the Bentley i-model Interchange Format and we have a reader for it in FME Form. If the i-twin model API works with it.

Hope this helps.
