I want to display the file name of the 3D model (may be a single part or an Assembly) on the Drawing's itle block,

I realized that uising the below only shows the file name of the Drawing file rather than the 3D model:

"CAD File name: \$PRP:"SW-File Name", i.e., SW-File Name is actually the file name of the 2D Drawing, and not the 3D model.

How do I do it correctly?

Thanks,

Victor
