Summary

Created vertices from linestring geometries when convering GIS object to Model object.

Example

import wntr

wn_path = "io.inp"

wn = wntr.network.WaterNetworkModel(wn_path)
wn_gis = wn.to_gis()
wn_from_gis = wntr.network.io.from_gis(wn_gis)

# print vertices
for link_name in wn.link_name_list:
    link = wn.get_link(link_name)
    print(link.vertices)
# prints
# [(15.0, 5.0), (20.0, 5.0)]
# []
# []
# []
# []
# []

for link_name in wn_from_gis.link_name_list:
    link = wn_from_gis.get_link(link_name)
    print(link.vertices)
# now prints
# [(15.0, 5.0), (20.0, 5.0)]
# []
# []
# []
# []
# []
