Starting with MWO version 15, units are tied to a specific Layout Process File (LPF). This allows hierarchical, multi-technology designs to use different units based on the technology. For instance, a hierarchical design composed of PCB and integrated circuits may have one length unit tied to the PCB and another tied to the IC. This simplifies the layout editing of each technology. Previously, the entire project was forced into a single set of units. This video demonstrates how to setup a project that will support LPF dependent units.
