Anchors

The Overhead Design Analysis (OHDA) tool 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, you will need to:

Define specifications in an XML file, as detailed below.
Save the XML file:
- in the Bin folder of your ArcFM installation, the default being C:\Program Files (x86)\Miner and Miner\ArcFM Solution\Bin on a 64-bit system.
- AnchorSpecs.xml must be the filename.

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>	Assembly Creator creates and records a unique id for 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.
