I was able to connect as is with both ArcGIS Pro 3.5 and the latest TBC (2025.21). I was able to read features in from GIS. I believe the issue is that you need a corresponding FXL somewhere along the line to process features codes (putting features on the correct layers) and then write to GIS. See the attached reports from reading and writing. Also, i wouldn't recommend leaving your feature classes in WGS84 but rather the california zone 1 usft, nad83 2011. Lastly, if you are using TBC to generate the GDB to begin with, i would recommend brining the layers into ArcGIS pro and defining based on ESRI's coord system library and clear the vertical CRS. I see that TBC reads in the GDB layers and seems to be multiplying by 3.280833333 to get to USFT from meters. It's already in feet so that definition may be causing the erroneous conversion.

I emailed you access to a zip file of the gdb. Thank you for taking a look.

Andrew, I am very familiar with the GIS module workflow. Might you be willing to share the Geodatabase? Per the most common workflow, TBC is expecting a GDB that was created in ESRI. That being said, you should be able to create a GDB with TBC and connect to it and write to it. The key is being consistent with your coordinate system and datum here. If you have TBC set to something like state plane az central, int foot, nad83 2011, and Geoid 18 int foot, when you create that GDB, it should honor that system (if exported as grid with northern/eastings). Then, you would connect to it via the GIS connection manager and tell TBC that you are considering those systems (GDB and TBC project data) to be the same. Finally, you should then be able to write to GIS. Keep in mind that the schema needs to match identically. in other words, if you tweaked any layers/feature codes/attributes after doing the initial export and connecting to the Geodatabase, you would have write/Read issues.

Guys,
I keep running into an issue with "Write to GIS." I've created a geodatabase by exporting FROM TBC when I try to Connect back TO that database in TBC I get this:

I've tried 'output horizontal' as "Grid" and "Global" when exporting with the same result. If I Click "Yes" here anything I "Write to GIS" will indeed be in a completely different system then the original exported data in the geodata base. All this from the same TBC project. What am I missing here?
