Hi,
The wiring harness module in SE can import txt files containing wire,cable and connection definition and create an automatic wiring harness using predefined connectors on assembly parts (or defined on the fly).
PCBto3D works well to import IFD format: brd/lib, emn/emp, and others (bdf,idb). No succes with PADS format (acs). When importing, the process is sometimes time consumming. One of its advantage is that each feature like different holes are separate entities.
Another PCB import software is Desktop/EDA for Solid Edge (IDF 3D modeler). It is faster, a bit more user-friendly and a bit better with PADS format. The only disadvantage I could see was that the features were grouped and not as easily filtered.
