You have to add the Subgrid to Coordinate System Manager for it to show up
in the list
Go to Windows Start key - Trimble Office - Coordinate System Manager
In there Select Geoid Models
Press the + button in the icons at the top of the dialog
Name the Geoid and the Export Name (use the same name) and then pull down
the list where it says File Name - your Subgrid File should be in that list.
Once you have created it in CSM - then you can select it in TBC.
As I said earlier - I am trying to find out if Subgridding happens
automatically (it should and maybe it has been broken in v5+ if it worked
in earlier versions of BC-HCE) - my main source of this level of detail is
reluctant to go hunt this down for me - (it must be tough to find that in
the code base if he is being that tricky ....) so I have no way of telling
what is happening there - I can hunt around some more tomorrow. myself.
SCS900 and Siteworks and now Earthworks I understand all can use the full
Geoid Model without subgridding - however these older systems are more
tricky because they were developed for hardware that was not as good as
that available today - and while we would love to be able to go back and
fix all of the old code bases for legacy products, it just is not
economically viable to do so unfortunately - and as you can see with each
version of Firmware and Software things changed and improved with time but
when you go way back to 12.4 etc, there is no way that we can fix every
version that we ever created etc.
Hope that this is helpful at least
