Definition of Hanger Attributes

The following chart explains what attributes mean, and also lists attributes that users must define when they are building new parts. The meaning of many attributes is obvious, such as nominal size. However, there are other attributes for which users may need explanation.  

Most columns below are self-explanatory. Note the following points:

 

Class Attribute Name Required Type Value Discrete list location Definition Usage More Information
Support Part Hanger Specification No string discrete Chapter names in material spec catalog   1) Allows the user to select the required Hanger from the catalog during placement time.
2) Propagate attribute values from the specification to the Hanger being placed.		  
  MaterialCategory No string discrete Discrete Values directory   During Hanger placement, this attribute can be used to filter the catalog in order to select the required Hanger. The value will also propagate to the Hanger if a value is not already defined.  
  PartName No string discrete Family in design rules catalog Name of part under a Part Type
(I.e. Type = "Rack Trapeze Style"; Name = "Overhead Trapeze")		 During Hanger placement, this attribute can be used to filter the catalog in order to select the required Hanger.  
  SymbolName No string discrete Family in design rules catalog Name of specific part under a Part Name

Rack NumberOfTiers Yes integer single n/a The number of tiers attribute must be defined to allow proper geometry visualization. The geometry of the tiers should be tied to this parameter. During the geometry definition, the user will have to define rules that will drive the geometry display of the tiers. If the value of the "NumberOfTiers" attribute is set to 2 by the user, then the geometry corresponding to the 2 tiers should be displayed. All other tier geometry should be deactivated. Will be calculated when a hanger is inserted in a loft or when a hanger replaces a section. The user may also key in this value.

  TierWidth Yes length single n/a Hanger section Width. Defines the Width of the Lofted Pathway. This attribute should be associated to the geometry of the section that is included as part of the Hanger definition. This is important to ensure that the geometry will resize correctly when this parameter is modified.  Will be calculated when a hanger is inserted in a loft or when a hanger replaces a section. The user may also key in this value. In Edit Parameters, if this parameter is changed and the hanger has cables routed through it, the cables may be adjust accordingly.

At placement time, value is propagated to the hanger from a default that is defined by the Hanger specification or the project (PRM). During Cable routing, the growth factor is used to validate the computed cable route path. If the Hanger that is included in the computed cable route path is overloaded due to Growth factor limitation, then the cable route path will be rejected. If (Percentage Fill + GrowthFactor) > 100, Hanger will be an overloaded Hanger
  KeyStationNumber No string single n/a Key station name(alpanumeric). This name is defined based on several rules: The geometric position of the Hanger (Compartment, Deck, etc.), a unique sequence number within a specific Deck, etc. The Key station name gives the user the ability to determine the location of the Hanger by looking at this defined name. A classified hanger is very likely to have most of the cable passing through in its immediate network vicinity.
  CableVolumeHeight Yes (Electrical) length single n/a Hanger section Height. Defines the height of the Lofted Pathway. The geometry of the Hanger section must be associated to this attribute.  The "CableVolumeHeight" will drive the geometry definition of the section. The attribute should be defined based on the available number of Tiers attribute such that if the number of tiers changes, the value of this attribute must change. The value of the parameter must be defined during part build. The value should be computed form the NumberOfTiers and the TierSpacings
  RackSize Yes (Electrical) length single n/a Total available space that can be used for cable routing for the Hanger. The growth factor is included in the RackSize definition. When you insert Hanger on a Loft, the Hanger TierWidth will be computed based on the RackSize. The cable route will be computed based on the Hanger RackSize availability. The Hanger is considered full if the Racksize is totally used.  RackSize = NumberOfTiers * (TierWidth - (NumberOfLegs * LegWidth))
  TierHeight Yes length single n/a   Required when trying to compute the space available between 2 Tiers. The space available will determine if a cable can be routed. 1) Can be automatically valuated using a design table.
2) When a design table is used, the user must associate this design table to the Hanger. The design table can contain values for all Tier related attributes.
3) Available space = TierSpacing - CableCleanrance - TierHeight
  CableClearance Yes length single n/a Minimum space that must be available between the top of the cable to the bottom of the higher tier 1)  Value is propagated to the hanger from a default that is define by the Hanger specification or the project (PRM)
2)  Required when trying to compute the space available between 2 Tiers. The space available will determine if a cable can be routed.		 Available space = TierSpacing - CableCleanrance - TierHeight
  TierMaterial Yes string single n/a   During Hanger placement, the user can select the TierWidth in the "Section Definition" fields. For this purpose, the TierMaterial is required to help locate the required TierWidth in a design table. If a design table is used to define the TierWidth, then the TierMaterial will be used to ensure uniqueness of each row in the design table.
