This tool is useful when a user has a Z shape polygon (2d_zsh) and wants to assign perimeter elevations. The workflow for this process would be:
<ol>
<li>The user starts with a Z shape polygon (2d_zsh) that is read into the TUFLOW Geometry control file (TGC) using the " <tt><font color="blue">Read GIS Z Shape</font><font color="red"> ==</font></tt> " command. Additional line and point layers may also be included.<br>
'''Note:''' Other Z shape layers (points and lines), may also be specified in the model, using the same " <tt><font color="blue">Read GIS Z Shape</font><font color="red"> ==</font></tt> " command (shown in the example below).
<li>Run the tool to generate a new polygon and points layer. The polygon layer will optionally have additional vertices, and the points layer will have elevations assigned.
<li>The TGC command is then updated to reference the newly generated layers, instead of the original polygon. For example:<br>
'''Before:'''<br>
<tt><font color="blue">Read GIS Z Shape</font><font color="red"> == </font> 2d_zsh_example_polygon | 2d_zsh_example_lines !| And2d_zsh_example_points potentially other<font linecolor="green"> and! pointTopography layersFeatures</font></tt><br>
'''After:'''<br>
<tt><font color="blue">Read GIS Z Shape</font><font color="red"> == </font> 2d_zsh_generated_polygon | 2d_zsh_generated_points | 2d_zsh_example_lines | !2d_zsh_example_points And potentially<font othercolor="green"> line and! pointTopography layersFeatures</font></tt>
</ol>
