I was recently working with a client on getting electrical receptacles to show with a solid gray fill to represent when the receptacle is connected to an emergency power circuit. Since receptacles are shown as annotative symbols in plan views, it created a different situation than can be done in non-annotative families. In non-annotative families, you can create the solid fill and send it to the back so linework can be seen on top of the fill. With an annotative family, fill patterns are in masking regions and will cover any linework that might also be in the family. This meant that a different approach needed to be utilized to get the circular solid gray fill to not cover the symbolic lines going through the electrical receptacle.
This article will look at how to create the fill to display correctly, and also how to make the fill display only when you specify that the receptacle is on an emergency power circuit.
