I have now posted a new version of the Sincpac-C3D that adds some significant enhancements geared toward Surveyors.
The main improvements are the new DISPLAYPOINTS and DISPLAYPROFILE commands. With these commands, I'm exploring some alternatives to reports, because I'm really not happy with the way they work. In many respects, these two commands are "dynamic, interactive reports, that can still dump the data out to a CSV file, with no need for extracting the data from a formatted web page". In other words, I think they are more-useful for Surveyors than the reports Autodesk gave us.
There's also a command for adding Station/Offset to point descriptions (so the Station/Offset appears in exported PNEZD files, unlike Station/Offset Labels), a command for pruning PVIs from existing profiles, a command for converting an EG profile into an FG profile, and a command for cleaning up duplicate vertices in polylines (all kinds).
That's just the new commands in this release. The Sincpac-C3D already contained a wealth of routines that help in the Surveyor's line of work, and some of the existing commands have also been improved in this version.
And this is still just the beginning. The DISPLAYPOINTS and DISPLAYPROFILE commands offer only a glimpse of the functionality that I envision.

It's already to the point where I can't imagine any Surveyor trying to use Civil-3D without the Sincpac-C3D. It just saves way too much time, and makes arduous tasks so much easier. Eventually, my goal is to make Civil-3D+Sincpac-C3D the only sane choice for Surveyors. I haven't concentrated on replacing the FBK process yet, since so many other third-party providers have already covered that one, but I think I'm addressing a lot of needs that no one else is.

Crazy? Maybe, since according to JP, the Surveyor market isn't big enough for Autodesk to care about. But I'm a Surveyor, and I think this technology has more potential than any other solution out there, once the "holes" left by Autodesk start getting filled in (as best we can fill them with third-party technology, anyway).
