Problem
When importing catchments from a data source that does not include the geometry (shape/vertices), each catchment appears as a green pentagon shape. What can be done to better visualize the catchments in the drawing?
Or... how can I import and assign catchment areas for a large number of catchbasins?
Solution
Catchments (or any other polygon element type) that are imported from a data source type that does not include geometry, will import as the default pentagon shape.
There is no way to scale up or down the catchment shapes in the Standalone version, but you can manually change the shape by manipulating the vertices or using right click >add/remove bend. Some other options to consider:
1) Uncheck the catchment layer in element symbology to make them disappear from view (they will still be included in the calculations but won't clutter up your plan view)
2) import catchments from a data source type that does include the geometry such as from a GIS source (ex: shapefiles).
3) (StormCAD) Using Modelbuilder, import the contributing areas directly into the catchbasins instead of importing catchments. (External CA and External Tc fields)
Enhancement #186866 has been filed for the ability to split catchments, though this is something you may be able to do in another platform such as SewerGEMS for ArcGIS.
