* Only two vertices crossing the 1D network.
* In case of more than two vertices, one must be snapped onto a 1D network vertex.
The 1d_xs or 1d_tab layer references an external csv file (or similar formatted file) containing either a cross-section profile or a hydraulic properties table. The hydraulic properties can also be externally sourced from a Mike 11 or Flood Modeller. Note that structures such as culverts (circular and rectangular only) and weirs, are an exception to the rule. The attribute information supplied within the 1d_nwk table are sufficient to define the hydraulic properties. <br>
