    Description

    For transfomation of coordinates inside of Civil 3D / Map 3D there are two possible ways. The differences between parameter- and affine transformation is shown. The affine transformation is using NTV2 files. In many cases there file for download from surveying offices, but you can also create your own. How that works and the way to implement the NTV2 files into your system are shown.
