UK Electrical Symbols

[Katalyst777]

Looking over the Pro 2012 and X4 Premier trial versions, it looks like only the Premier would let you change actually the 2D CAD Block that is associated with a 3D Symbol.

Although, in Pro, you could create your own library of CAD objects (or import them from a DXF if you find a good one online somewhere) for the electrical items, block them together, and add them to the Library Browser.

You could also import images of the 2D symbols to place in floor plan view.
