Hello @dongho.shin  
There are few posts on the forum discussing how to traverse to PRC, for example this [post](https://forum.techsoft3d.com/t/how-to-traverse-a-prc-model-file-using-visitor-pattern-for-rapid-prototyping/1456) may help in understanding how to get A3DRiRepresentationItem.  
Or you can refer to the default sample PRC2XML for traversal or sample Viewer/MeshViewer. The API `A3DRiRepresentationItemComputeTessellation` is used in the sample.

Best Regards,  
Man
