Create Diagnostic Polygons Dialog

The Create Diagnostic Polygons Dialog is used when generating polygons by intersecting subcatchments, existing polygons or GIS sources.

The dialog is displayed when Geometry | Create diagnostic polygons is selected from the Model menu.

The dialog comprises several sections, each of which contains similar options:

Dialog Option	Description
Network Object	Dropdown list of network objects that can be selected for intersection.
Layer	Dropdown list of GIS layers that can be selected for intersection. If the list is empty, it is possible to add layers without leaving this dialog, by clicking on the Browse Layers button.
Selection check box	If one or more objects is/are selected on the GeoPlan, this button can be used to indicate that only the selection is to be considered.
Browse Layers button	Clicking on this button opens the GIS Layer Control Dialog, where layers can be added to the network and displayed on the GeoPlan view.
Apply Themes check box	This check box is ticked by default and indicates that a default theme will be applied to the created polygons so that any suspect polygon is easily visually identifiable. The original polygons are hidden by this default theme.
