Thank you. And excuse my ignorance, but how do wrl files relate to the 3dxf files that FF uses?

There's a chapter on that in the manual starting on page 149, but the short version is the .wrl files are in VRML format which FrameForge can natively read and internally convert into true FrameForge 3D Objects including hinges and optional parts if set up according to our guidelines.
