I am working on a zoning project for a small town in Montana and the layers I made into shapefiles from DGN files I have are in an unknown local coordinate system. I want to change them to a global coordinate system (e.g. WGS 1984 or State Plane Montana), but I have no idea how to start. Every time I define the projection, my layers are VERY disproportionate and in a totally wrong location. How to I go about changing local coordinates?
