===From DEM===

The cross-section can be generated by cutting a section from an open raster layer. This can be done by using "From DEM > [select desired DEM]" then drawing a line in the map window (left-click to add a vertex, and right-click to finish). The drawn line will not be used when generating the spatial location of any 1d_xs feature and can therefore be drawn anyway and does not need to intersect the arch bridge polyline (e.g. it could be drawn upstream of the bridge as a representative cross-section).<br>

 

The graphic layer can be cleared from the map window using "Clear Graphic". The graphic layer can also be exported to a SHP file by using "Graphic -> Layer".
