shrug-l: Reprojection Issues

[Kristal Walsh]

It would tend to make me question the native projection of the dataset.
I have on several occasions interactively defined the dataset in exactly
the same projection and only an import would work.  By this I mean, if
you have other data in the SPCS projection that do line up with your
Albers data, then import that spatial reference information to your
feature classes instead of interactively choosing your coordinate system
and datum. There are also several variations of NAD83 in the ESRI
coordinate system files; make sure to grab the right one.  Good luck!

Good Morning Shruggers, 

We are having issues with reprojecting feature classes we have extracted
from our DGN files.  I have extracted the data we needed into feature
class form, and defined their projection in Florida State Plane North.
All of our DGN files are created in the Florida State Plane NAD83
coordinate system.   

However, I am attempting to reproject these feature classes into Albers,
but, everytime I bring them into ArcMap they look exaclty like they did
when they were defined in State Plane.  They are not lining up with any
data that is in the Albers projection.   

Does anyone have any ideas on what might be going on?  I have seen this
happen before, but only when we did not define the projection before
attempting to reproject, but in this case, that isn't the issue.  I have
also attempted this process on shapefiles vs. feature classes as well,
and nothing seems to work. Thanks!
