I have some errors in HEC-GeoRAS for ARCGIS 9 that i can't solve.

- When i run STREAM CENTERLINE ATTIBUTES - ELEVATIONS this error message appear: '91, object variable or With block variable not set'. Stream centerline layer has all the fields filled and is a continuos and oriented line.

- When i run XS CUT LINE ATTRIBUTES - ELEVATIONS this error message appear: 'CalcXSReachlenghtWK: 20001 No features found in flowpath layer'. Flowpath layer is a copy of centerline layer, it has all the fields filled and is a continuos and oriented line.

Anyone could help me?
I'm using a TIN model and there is a junction with two rivers.

There is no reason to run the Stream Centerline > Elevations...RAS doesn't accept the elevation data, so skip it.

The error message with the XS Cut Lines > Elevations makes no sense. It gives you a flow path error? It looks more like you are trying to compute flow paths, but the flow path feature class is not properly created or specified.
