Is it possible to reproject a WaterGEMS, WaterCAD or SewerGEMS model?
As of version 08.11.05.61 (WaterGEMS) and 08.11.05.58 (SewerGEMS),there is no direct tool for doing this in either standalone or ArcMap integrated mode.However, you can utilize the "Project" tool from Arc Toolbox, if you ownEsri ArcGIS. Note that when doing this, you must create a new featuredataset. Unfortunately, this breaks the link between the WaterGEMSdatabase and the geodatabase. Please follow these steps for aworkaround:1) Back up your model.2) Use the Arc toolbox "project" tool to reproject the WaterGEMS model'sassociates personal geodatabase. Choose a new feature dataset in thesame geodatabase, with a different name.3) When done, delete the original feature dataset and then rename thenewly projected dataset to the old name. You will also need to renameeach feature class (PRV, pipe, junction, etc) since a '_1' will beappended to the end. Remove the '_1' from each of these.4) Close Arc Toolbox and open the geodatabase in a database program suchas Microsoft Access. Locate the table named "GDB_ObjectClasses" and notethe range of numbers in the "ID" field (the first number at the top, inparticular)5) Close this table and open the table named "WaterGEMSClassMap". Youwill see a table for "FeatureClassId". Basically, these numbers nolonger match up with the ID's you saw in the "GDB_ObjectClasses". Youmust renumber this field, matching the "FeatureClassId" to the samefeature class type (PRV, pipe, etc) from "GDB_ObjectClasses". Mostlikely, you can simply start with the lowest number you saw in"GDB_ObjectClasses" and increment up from there.6) Open the project in arcmap. It will appear to be reprojected but inactuality, the WaterGEMS database has not been updated with the newgeometry. Export all the layers (pipe, PRV, junction, etc) to shapefiles(this will ensure that labels are exported with it)7) Close ArcMap and open the .wtg file in WaterGEMS standalone. Runmodelbuilder, using all of the exported shapefiles as the source.8) Uncheck all spatial creation options and choose only the label fieldsfor the table linkings for each element type. This should synchronizejust the geometry (x/y)9) Open the project in arcmap. Both the geodatabase and the Watergemsdatabase should be in agreement.In WaterCAD, since you cannot integrate with ArcGIS, you would need toexport each element type to a shapefile (via the export button in theflextables), reproject in ArcGIS, then update the geometry usingModelbuilder.
