The Library menu provides access to screens to configure poles, conductors, assemblies, components, cable arrangements, mid-cable objects, soil layers, and more:
Poles library
Add, remove, and edit poles in the Project:
Edit individual values
To edit an individual pole's property value, double-click its cell. Changes are saved automatically when you click outside the cell.
Bulk edits
To make it efficient to make a large number of changes to the Pole library, these options are available in the upper-right:
Note: Use Metric units when importing Pole and Conductor values from CSV files
Import: Prompts you to upload, and import one or more poles from, a Comma Separated Value (.CSV) file. To see the expected CSV format, first perform an Export and view the file in a spreadsheet or text editor app. Remember to save your changes in CSV format. Note that Neara sets and uses a unique identifier for each pole in the library and pole names may not be unique. This means that if your CSV file includes a pole with the same name as an existing pole in your library, both will be listed in the library after import.
Replace: This performs two actions, in order:
Removes unused poles
Prompts you to upload a CSV file containing new poles to import
Export: Immediately downloads the current pole library to a CSV file to your computer
Remove unused: Removes all poles from the project's library which are not used in the design in the current project. This cannot be undone, so we recommend that you Export your library first and before running this.
Conductors library
The Conductor library works in a similar way to the Pole library:
Assemblies library
The Assemblies library contains all the existing assemblies that exist in your project, and makes it easy to both bulk edit and finely-tune values:
For more information on using this Library see: Assemblies Library
Components library
Similar to Assemblies, aspects of different components can be modified in this library, to change the physical size and adjust different force tolerances, modifying how Finite Element Analysis (FEA) is calculated:
For more information about the items in this library, see: Create a new Component
Mid-cable objects library
Mid-cable objects are additional objects that can be placed along a cable span to simulate real-world scenarios.
Neara supports the modelling of 4 different types of mid-cable objects that attach to a single cable of a span. These include marker balls, rota markers, vibration dampers and tiger tails.
You can visualise and perform various dynamic analyses such as Finite Element Analysis (FEA) on constructions with these mid-cable objects attached.
For more information see: Creating and attaching Mid-cable Objects to spans
Soil layers library
The Soil layers library manages the different types of soil layers that can be used:
To delete an entire soil layer, click the delete (x) icon on that layer's row.
To modify a soil layer, click the Edit option in that layer's row:
You can modify existing values within each of that soil's layers, and Add Layers within that soil layer. To remove a layer within that soil layer, click the red delete (x) icon. Click Apply to save any changes made, and click outside the popup to close it.
Creating custom components and constructions
To create new constructions, we recommend that you first create the components that form the pole top construction:
Select Library menu
Select Components menu option
To make the component, find a component that reflects the type of component that you are trying to model. For example, if you are trying to make a post insulator, find an existing generic post insulator:
Search up the construction type in the search bar, for example: Post Insulator
Select make a copy (at the bottom right)
Rename the copy and press OK
Enter in your design specs into the available fields and select save
Once you have modelled all your components, you can then fit them together in the Assemblies Library:
Select Library menu
Select Constructions menu item
To make the pole top constructions, find a construction that uses the same number of cables you are trying to model with the new construction.
This example will model a 3 wire vertical construction:
Search for 3 wire vertical to find similar constructions
Click each construction to check its configuration in the the preview
When you have identified a suitable one, select Make a Copy
Give the new construction a name, and click OK
After the copy is created, scroll down inside its configuration to add crossarms and change the type of insulators being used.
Adding Crossarms
Select Add New Crossarm
Select the type of beam to use
Enter in the horizontal/vertical offsets
Select the type of brace to attach
Define the attach offset
Fitting insulators
Select the dropdown Usage type to define your insulators as termination or through unstrained
Select the type of insulators to be used
Attach it to the respective crossarms or pole
Define its offset and angle of rotation
Finally, click Save to save the new construction.
