ArcGIS 10.4

Is there a reason that in ArcGIS 10.4 when I Define Projection a raster the z-coordinate is not showing? I've tried the same raster on 10.6 and it projects the z-coordinate but for what I am working on it requires me to use the older version since a toolbar is not yet available for the recent ArcGIS.

Grids usually don't have attribute tables. The values are stored in the cells of the raster.

Hey guys, after trying another run, i found where the problem is. You must keep the basin name e.g. Subbasin155 as the same as the basin table header name e.g. basinheader155. Which means in the process of running HEC-GeoHMS, its better not change anything that being set as default...

HEC-GeoRAS and HEC-GeoHMS for ArcGIS 10.6

Hello! I know there is a version of HEC-GeoRAS and HEC-GeoHMS for ArcGIS 10.5. I need these two plugins for ArcGIS 10.6. Does anybody know where I can find such versions? I searched in this link, but for version 10.6 doesnt exist yet. Do I have to downgrade the arcgis version? http://downloads.esri.com/archydro/ Thanks

Flow directions in the 4 cardinal directions only (North, East, South and West)

Hello! I would like to know if there is a way to calculate the flow directions in the 4 cardinal directions only (North, East, South and West). Indeed, ArcGIS transfers the flows in the 8 directions, which I don't want. Does anyone have any idea how to proceed?
