Although most people would prefer to have files in state plane coordinates. If data was provided in un-projected space, would you consider the data unusable in Arcmap for use with the parcel fabric? Let me know of your thoughts. I have data that is both in projected and un-projected space.
I can clarify more when people comment on this.
Thanks,
Dave
Dave, I don't think you will be able to create a parcel fabric or load data into it that does not have a defined projection which is the same as the feature dataset. A parcel fabric can only exist in a geodatabase feature dataset and the properties of a feature dataset require that it have a projection and all feature classes within it have the same projection. Does help answer your question or is there something more?
Thanks,
Ben
