:* Input TIN File: Select the relevant XPSWMM Input TIN file.
:* Output File Format: 'ASCII Grid File Format'.
:* Cell Size Value: Choose a suitable DTM resolution. This resolution should be finer than the hydraulic model resolution. Typically, a DTM resolution is 1/10th5th (orto smaller)1/10th of the hydraulic model 2D cell size is common. <br>
::'''Note:''' XPSWMM requires an integer cell size value for this export step. For example, Cell Size Values of 1 , 2, 3, 4 , 5 ... are suitable. The XPSWMM export will not function if you specify a decimal cell size value (eg. 0.5, 2.5 etc.).''
<li> Click 'Export'.
<li> Save the file to the folder where XPSWMM writes the .tcf during its simulation preprocessing. By default, this is the '''2D\Data''' folder. <br>
