Has anyone created a 3d STEP file viewer for Ignition Perspective?

I am by no means a web developer but using resources online and a lot of AI help I was able to implement a DXF viewer that runs on Three.js hosted by the Webdev module. For anyone interested this library i used to get started. [GitHub - vagran/dxf-viewer: DXF 2D viewer written in JavaScript](https://github.com/vagran/dxf-viewer)

From what I have found the Three.js library does not support step files, it looks like there are some ways to implement step files in Three.js but not being a web developer I have hit a bunch of road blocks trying to get it working.

I do not want a big conversion process either, our CAD server auto create STEP files for all our 3d objects, so I want to be able to just utilize the existing framework rather than adding complexity by doing a file conversion to STL or some other file format.
