TUFLOW Message 1178

TUFLOW Message
ERROR 1178 - Reading channel network data. Check 1d_nwk layer has correct attributes.

Alternate Message
ERROR 1178 - Reading 1D network layer. Check 1d_nwk layer has correct attributes.
ERROR 1178 - Reading 1D network layer with extended attributes. Check 1d_nwk layer has correct attributes. Use "Read GIS Network Extended Off == " to use standard attributes.

Message Type
ERROR

Description
An error has occurred whilst reading 1d network data (1d_nwk). This may occur if the attribute types in the file do not match what TUFLOW is expecting for a 1d_nwk command.
It can also occur if ten or more extended attributes are used, omitting fields from the 1d_nwke layer.

Suggestions
Always use an empty 1d_nwk template file as the GIS entry for 1d_nwk inputs. DO NOT create empty 1d_nwk template files manually yourself. Use either TCF command, Write Empty MI Files == or Write Empty SHP Files == to create these template files. Also, ensure the layer has the correct attributes and ensure that the Read GIS Network == command is only used for network data, not 1D boundary or table links.
If ten or more extended attributes are used omitting fields from 1d_nwke layer, specify Read GIS Network Extended Off == command instead.
