Line 6: <li>Import in an empty <b>2d_bc_empty.mif</b> layer from within the '''FMT_tutorial\FMT_M01\TUFLOW\model\mi\empty''' folder.</li> <li>Save the layer as <b>2d_bc_FMT_M01_HX_001_P.TAB</b> in the '''FMT_tutorial\FMT_M01\TUFLOW\model\mi''' folder. </li> <li>Open the <b>~~1D_2D_Points~~1D_2D_Points_P.TAB</b> GIS layer from the '''Module_Data\Module_01\mi''' folder. Select all objects from within this layer, copy and paste into <b>2d_bc_FMT_M01_HX_001_P.TAB</b>. </li> <li>Interrogate one of the digitised points and inspect the attributes. The ‘type’ attribute is ‘ZP’ to denote that it is a z-point. The ‘f’ attribute is the elevation of the bank link in mAOD. </li> <li>Now add the layer <b>~~2d_bc_FMT_M01_HX_001_P~~2d_bc_FMT_M01_HX_001_L.TAB</b> from the '''FMT_tutorial\FMT_M01\TUFLOW\model\mi''' folder created in the previous step. Note that all the 'ZP' points created in the layer <b>2d_bc_FMT_M01_HX_001_P.TAB</b> are snapped to vertices of the layer <b>2d_bc_FMT_M01_HX_001_L.TAB</b>. This is because these two layers work together to define the bank locations and crest elevations. The layer line in <b>2d_bc_FMT_M01_HX_001_L.TAB</b> defines the location and the layer points in <b>2d_bc_FMT_M01_HX_001_P.TAB</b> defines the elevations. <br> [[File:FMT 1D-2D ZP.jpg]]
