An RD3 file is Topcon's proprietary file format for handling alignment data.
- To import an alignment, go to Data > Alignment > Import/Export > From RD3...
- You will be prompted to locate the RD3 file you wish to import. If the file is on a USB drive, you will need to navigate to the D:\ drive or USBHardDisk, depending on the type of data collector you are using.
- Highlight the file and hit the Open or Import button.

- If successful, Pocket3D should display the screen shown at right.
Even though an alignment file is being imported, Pocket3D will still give the message of "Imported 1 Surface(s)".
Importing an alignment will automatically make it the active alignment for stationing and offset values.
