Setting up and using Environments
Table of Contents
Neara Environments are pre-defined, customisable sets of environmental variables to apply in network model calculations, such as blowout or clearance measurement:
- Temperature;
- Wind;
- Ice/Snow;
- Cable and Structure Load Factors;
- Strength behaviors for poles, plants, and constructions; and
- Creep behaviour for conductors.
Use the Environments menu to view and modify these variables for a project:
Modifying environments
Color
Change an environment's color by clicking on the colour box. This will change the way they are represented in reporting and visualisations:
Enabled
Check/uncheck the Enabled checkbox next to an environment to enable or disable it from being viewed in DXF exports, the Profile view, or blowout visualisations.
Strength States and Derating Factor
Strength states are used in the analysis to derate the maximum strength of construction to a new allowable maximum.
Strength states are used and applied to an environment in the strength column.
For example the environment Max Wind is using the strength state Strength and in this strength state, wood poles are derated by a factor of 0.6:
With this applied factor, you can now see that in the Tip Load analysis of a pole the derated tip load limit is now 6.00 instead of its original strength of 10:
Importing/exporting environments
The environments table can be imported to and exported from a CSV file (or pasted from Excel) to ensure that multiple projects have the same custom environments configuration. Click the relevant links under the main table:
