This process has the potential to be a real nightmare, - a recipe for data disaster.
from the FG manual
After you have made your changes you can re-coordinate the raw file so the
changes are displayed on the screen and saved in the project database.
Note:
When you re-coordinate the raw file it will process the whole file from
beginning to end. This means if you have changed the coordinate information
for a point there is a chance that it will be changed back to its original value if it
was measured and recorded in the raw file.
It appears this doesn't work in certain areas where data is calculated from measured points. Therefore some points get re-cordinated and some that should dont.
I suggest an insert in the Manual giving more specific details and appropriate cautions would be a welcome addition please.
