Sure. Import the HV1.pts and HV2.pts files (PNEZD comman delimited) and then the T9 (rename to .fbk, had to change for attachment to forum). Make a check to a target height using browse to survey observations and see if it updates the elevation.
I'm using C3D 2012 sp2, Win7 64bit, FYI.
The problem is that the Survey Network and Survey Points needed to be updated. Fortunately those can both be set to "Automatic Updated". Unfortunately my drawing crashes as soon as the network and survey points are refreshed.
