What I'm trying to do is use a point layer for three distinct displays but utlilize the layer once. So I will have three different scales that the layer will be accessed from multiple mxd's and I want them to be driven off a field called scale ( or something like that). Will using representation rules allow for this? Can I have the layer be dynamic and know when it gets to a certain scale to turn off\on different point features. Or any other thoughts on how to accomplish this?
