How do I change data in existing engineering libraries or add to it? For example, I want to add HDPE to the material library in WaterGEMS.
This example uses the Material library in WaterCAD/WaterGEMS, but the concept is the same for other library types.1) Go to Components > Engineering Libraries and click the plus sign next to "Material Libraries"2) Right click MaterialLibrary.xml and choose "add item" - a new material entry will appear at the bottom of the list. *If you only see the option to "Save as" or "Remove" you should try the following to resolve the issue using the steps found HERE.3) Right click this new material entry, choose rename and enter the name (such as 'HDPE').4) On the right side, enter the friction coefficients, Young's Modulus and Poisson's ratio for your new material, then click close. (Note: The Young's Modulus and Poisson's ratio are only necessary if you need to use the automatic wave speed calculator tool in HAMMER, under Tools > Wave Speed Calculator.)
There may be a case where you want to create a new engineer library file (.XML) instead of using an existing. You may also need to create an XML file because one does not exist, such as for the pump definition library. To create a new library file, you can select the New button and choose "New Library". Give the file a name and click Save to create the file. You can then use the steps above to add data to the new library file.
Again, this example uses the material library, but the concept is the same for other libraries.
1) Go to Components > Engineering Libraries and click the plus sign next to "Material Libraries"2) Click the plus sign next to the .xml file associated with your engineering library (such as MaterialLibrary.xml) 3) Click the item you would like to edit, change the value(s) on the right side, then click the Close button.
For the Conduit Catalogs in Select Series 4 and up the procedure is a little bit different. The first two step remain the same, but the last should be done as shown below.
3) Click on the item you would like to edit (it will be highlighted in blue) and this should bring up the properties for it on the right side of the window.
4) Locate where it says "Catalog Conduit Class Sizes" and click in the cell to the right of that where it says <Collection>. When you do this an ellipsis button will show up. Click that button to access different sizes in that library. Now you can make your changes.
