<br>The <font color="blue"><tt>Create TIN Zpts Write TIN </tt></font> command creates and writes a .2dm mesh file to the same location as the GIS layer (in this case the TUFLOW\model\gis folder). The .2dm TIN can be viewed, checked and modified in QGIS. This can then be read into the model directly using the <font color="blue"><tt>Read TIN zpts</tt></font> command for any subsequent model simulations.
<br>Our intention for the 2d_mat layers created in this module is for them to build upon the existing commands which modify roughness. We would like for the new layers to overwrite the existing layers at the location of the proposed development. This process of layering and building up the model is a powerful tool in TUFLOW that minimises data duplication and provides a means of quality control. We need to ensure that the commands reading in our new 2d_mat layers are read in after the existing commands.<br><u>'''QGIS - SHP'''</u></li>

Once the model has compiled and the simulation started, we can review the check files to ensure the changes have been correctly applied. The following section of this module outlines how the generated check files can be used to review each of the key changes we have made to the model. Note that there is often more than one check file that can be used to review each component of the model. The below steps outline just how some of these check files can be used.
'''Review Created TIN'''
From the <b>TUFLOW\check\2d\</b> folder open within QGIS:
Line 160 ⟶ 155:
The FMT_M02_001_DEM_Z.TIF is a grid of the final zpts used by TUFLOW after processing of each of the layers within the TGC. It can be read by most mainstream GIS software and also visualised in SMS.
'''Review Changes to Roughness'''
From the <b>TUFLOW\check\2d\</b> folder open within QGIS:
Line 170 ⟶ 165:
*By right clicking on the grd_check layer within the table of contents and click Properties. Once the properties dialogue window is open select the Symbology tab. Choose the Unique values option under Categories in the left-hand list and map the Value Field of interest.
'''Review Pipe Network'''
From the <b>TUFLOW\check\1d\</b> folder open within QGIS:
