Snapping is probably the source of 95% of TUFLOW pre-processing errors so it is highly recommended that the snapping is check prior to being added a network to TUFLOW.

<li> Ensure that '''1d_nwk_MI01_Pipes_001_L_EG1_ID1''' is referenced in the 1D network Line Layers and select the '''Snapping''' tab.
<li> Select the option to '''‘Use an exclusion radius when checking for snapping’''' and set the exclusion radius to '''‘1’'''. Run the tool. The ‘Exclusion Radius’ will not flag snapping errors for lines if the nearest line end is outside the exclusion radius.<br>

Line 12:
<li> Add the '''1d_nwk_MI01_Pits_001_P.shp''' file to the ‘Input Network Points’ section of the 1D integrity tool. This will enable us to ensure points and lines are both snapped together.
<li> Rerun the snapping tools but on this occasion select the option to '''‘Auto-Snap’'''. Set the '''‘Search Radius’''' to 1m.<br>
