Library Lists for Beam Sections, Shell Properties, and Spring Properties
You can save beam section definitions, shell properties, and spring stiffness properties in property-specific libraries. These libraries are a convenient way to use the same property definition for more than one model. There is no limit to the number of property definitions you can have in a model or in your library. You can use the library lists on the Beam Sections, Shell Properties, and Spring Properties dialog boxes to add property definitions to these libraries, or to move property definitions from a library to your model. For information on how Creo Simulate saves the libraries, see Managing Library Files.
Adding to the libraries — After you create a property definition, use the left arrow button on the appropriate dialog box to move the definition from the Entity in Model list to the Entity in Library list. This places the current property definition in your library. Be aware that Creo Simulate creates and saves the property-specific library file as soon as you move the first property from the Entity in Model list to the Entity in Library list. .
If the property definition you are adding has the same name as a definition already in the library, Creo Simulate tells you that the name already exists and asks if you want to overwrite it. If you select No, Creo Simulate does not add the current definition to the library.
You cannot, overwrite a property definition in the Entity in Model list with a property definition with the same name from the Entity in Library list. If you create a new property definition with the same name as a definition already in the library, the left arrow button becomes inactive.
Editing library definitions — To edit a property definition from the library, use the right arrow button to move the property definition from the Entity in Library list to the Entity in Model list and select Edit to open the dialog box that you used to create the property definition. When you are finished editing, use the left arrow button to move it back to the Entity in Library list.
