:'''Note:''' If 'Use DTM' was selected, please continue through the steps below. Otherwise, <u>do not</u> complete these steps; continue to the <u>[[XPSWMM_Conversion_TUFLOW_Structure | Convert XPSWMM Model to Recommended TUFLOW Structure]]</u> section.
XPSWMM provides two options for preprocessing the DTM to be used in the TUFLOW model, both options are outlined below. As
=== Option 1 (recommended) - Use Original Source Elevation Data Imported to XPSWMM
<ol>
<li> Locate the original 'Grid' file (.asc or .flt/.hdr format). Save it to the folder where XPSWMM writes the .tcf during its simulation preprocessing. By default, this is the '''2D\Data''' folder. <br>
Line 37:
<li> Tick on 'Use grid file for topography' and select '...' to navigate to the Grid file saved in the '''2D\Data''' folder. This file will be read directly into TUFLOW.
<li> Click 'OK' to save the settings.
<li> If these steps worked as expected, skip 'Option 2' and continue to the <u>[[XPSWMM_Conversion_TUFLOW_Structure | Convert XPSWMM Model to Recommended TUFLOW Structure]]</u> section. Otherwise, proceed to
</ol>

=== Option 2 - Export DTM Data from XPSWMM
<ol>
<li> In the XPSWMM Layers panel, under 'Topography', right click on '''DTM''' and select 'Export DTM Data'.
