HydroSWMM is installed with a series of themes that the user can select in order to view the model. (Advanced users can add to or edit these themes). Click on File > Theme Settings > Default Theme Settings reveal the following settings:
Choose a pre-loaded default theme (themes will be discussed in more detail further on in the guide) to be used when loading a model. The drop-down list provides a list of all the available themes.
Next, choose a default theme to be displayed after a model has been analysed (for now click Reset to none to have manual control over the theme to be displayed). Once the desired settings have been entered, click the OK button to close.
