Dan, thank you for your help. To better describe our process...we obtain a project scale factor about the center of our project and apply said factor about the origin, for example, if I have a grid coordinate of 500000, 1500000 and a scale factor of 1.000098756, the ground coordinate will be 500049.378, 1500148.134. Once I have completed my cad work, other members of the team need to bring it into Arcmap. Because most resources are on State Plane Grid, I need to be able to import the cad file into Arcmap and reverse the scaling to move the linework back to the grid location.
