Ah, that's why I don't see the option. The symbol is an electrical object, but the associated device is just a wireframe CAD block. I would think there's a way to associate, for example, a stove fixture with the appropriate relative utilities so that when the stove is relocated, the gas & electric moves with it. Is that not the case with CA, or would I need to make the "stove" a different type of block, such as converting it to an electrical object?
