Quick question: can C3D process raw/fbk files using SPC/combined factors/Geoid's, etc.?

Raw - No
Fbk - Yes

Thanks, but my real concern is whether it will process/adjust using combined factors and Geoid's.

It's best to do all that before bringing it into C3D. Obtain your correct coordinates then import.

Carlson has the option in the raw file processing to adjust using a scale factor, Earth curvature, and/or combined factor.

This is what I'm looking to see if C3D has processing/adjusting options like that.

I'm not talking about having a SPC system setup in my dwg/project.

The top lines of the FBK file usually have a line "SF 1.000000" for scale factor. You can change that to apply a scale factor to the distance measurements. You can add that line if it isn't already in the file. You can also add that line in other parts of the file to apply a different scale factor to the following measurements, such as when the survey covers a huge area with differing combined scale factors, or if the crew accidentally switched their units to meters somehow.
