Hi, thank you Vince and Cameron.

Q: Within RAS Mapper, does your 2D Mesh line up with your Terrain (i.e. same projection)?

A: So far everything tells me that yes. Even on the Bald Eagle example I get this error.

Q: Within RAS Mapper, if you right click the 2D Area layer under your geometry and select "Compute 2D Area Hydraulic Tables", what happens?

A: I get this warning:

I guess I have a problem with my projection like you said. I'll work trying to solve this now!

Q: The error states that your terrain file does not cover the 2D boundary. Is your terrain file larger than the 2D boundary extent?

A: I don't know how to answer this because even with the Bald Eagle example I get this error, are the demos are purposely defective?
