Hi guys, this is the process I want to follow - but I am unsure how to do it:

1) Build surface mesh in Gambit (I can do this) 2) Import surface mesh into T-grid and build boundary layers (I can also do this)

...3) How do I import the T-grid mesh with boundary layers back in Gambit?

in gambit, file->import->mesh

Yeah, I tried that, but it takes forever! Do I import 3d or Surface?

To date, the progress bar runs to 90% (1 million node mesh), and just hangs there

go to defaults in gambit and change the tri mesh value to -1, it may work, jus give a trial,
