I have several TIN files that I want to merge into a single TIN. Is there a way to do them all at once or append each one to the master surface? As I see it, I will have to merge surface 1 and surface 2 into surface1-2, then the resulting surface 1-2 plus surface 3 into surface 1-2-3, and so on. It gets pretty messy when there are 6 surfaces to be merged.

Neil,
you have got the process right.
You could bring the different TIN files into Modeler which would give you control to change the merge sequence.
Only other option is to append the data at "dat" file stage... and it really depends what form the data is in for this option to be viable.

The TIN's are built from DAT files which were extracted from DEM files . I thought about loading the triangles from all the TIN's and extracting them as graphics into a new surface but that approach doesn't clean up the edges where the TIN's overlap.
In any case I was not able to merge the TIN's due to some error during the process. These are 10 meter DEM's so the TIN's are quite large and I am probably just running out of memory. I may have to keep them seperate for now.
