I have just finished designing a 56km road. On completion we have been asked to tie the road to the national grid used by our local authorities. My coordinate system is WGS84 and the national grid is ARC 1960. The xyz shifts, given by the surveyor, between the two coordinate systems in WGS84 are δy=-63.447 δx=-13.931 δz=-0.232. I have tried having a geocentric translation on civil 3d 2012 but to no avail. What would be the simplest approach to applying this shift without having to start from scratch?
