Import
Selecting the Import button displays a series of dialogs for the import of 3D reference points contained within an ASCII file. Once the input ASCII file has been defined, you are provided within the Reference Import Parameters dialog. This dialog allows you to specify which projection, spheroid, and datum were used to collect these reference points. If the data is in a different projection, spheroid, and datum, the software transforms the data so that it conforms to the reference projection defined for the block. Once OK has been selected, you are presented with the Import Options dialog, which enables you to define specific ASCII format information associated with importing the ASCII file.
