From the developer:
PowerCad-PNL provides a live 2D interface to view your project's electrical system layout in Autodesk Revit MEP. Unconnected panelboards are displayed and boards can be renamed. The program also helps you find panelboards within your model with a function that locates a view where the panelboard is visible and selects it. The cable length between boards and the load on each board is displayed in the 2D interface.
