In O-Calc there are a number of options available to customize the tension on a span. These options can be found by selecting a span, and selecting the **Tension Sag** filter in the Data Entry Window.

    

When **Table** is selected, a Tension Table can be created by selecting the light blue dot to the right of the word “Tension”. That will open the **Span Tension vs Length** window.

Under the **Value** dropdown, span lengths can be added or removed. The tension at a given span length is linearly interpolated using the table.

When the desired span lengths are added, the tension at each length can be set.

Table must be saved under the **File>>Save **option before closing this window.
