Hi, I am currently developing a water network model using GIS data. The model is still in progress and hasn’t been finalised i.e. still need to fix error, connect customer meters, add pump curves etc. The model was working fine yesterday but this morning when I tried to open the model, it opened as a blank page. It still shows the elements in the flex table and co-ordinates of nodes but can’t see the network. If I select all pipes or junction and then click zoom to selected it then takes me to the network. But does not show the network when I open a model. The x and y ordinates are shown as NaN m as shown in the figure below. Further to this sometimes I am getting the following notification when I tried to open few other models. I will appreciate if you please help me with this issue. Thanks
