Anchors

Overhead Design Analysis (OHDA) is preset with several types of anchors. You have the option of using the default anchors or creating your own.

Unlike Poles and Cables, a separate XML file is not needed for each anchor.

Creating Anchors

To use your own anchors instead of the defaults, follow these steps:

Define specifications in an XML file, as detailed below.
Name the file AnchorSpecs.xml, and save it in the Assembly Library Location directory. This directory location is defined in the Assembly Creator on the Settings Tab.

XML Structure for Anchors

Tag	Definition
<AnchorSpecs>	Root element.
<AnchorSpec>	Container element for specification tags.
<AnchorType>	Name of anchor, combined with <MaxHoldingPowerMedium> to populate Assembly field in OHDA.
<MaxHoldingPowerSoft>	The anchor's holding strength in pounds (lbs) in soft terrain, displayed in OHDA once user selects Soil Type.
<MaxHoldingPowerMedium>	The anchor's holding strength in pounds (lbs) in terrain of medium density, displayed in OHDA once user selects Soil Type.
<MaxHoldingPowerHard>	The anchor's holding strength in pounds (lbs) in hard terrain, displayed in OHDA once user selects Soil Type.
<SpecUid>	A valid GUID to represent the anchor.

The attributes in all OHDA configuration files are defined using imperial units. The metric setting in the user interface does not change this behavior.
