The HvacSpecDefaults sheet in the HVAC.xls workbook defines the defaults in specifications that are available to you for HVAC routing. Currently, the workbook contains two specifications: Spec-0 and Spec-1.
SpecName
Type the name of the HVAC specification (for example, Spec-0).
TransAngle
Type a description of the transition angle. An example is 90 degrees.
TurnType
Type the name of the type of turn feature.
BendDiaMulti
Type the multiplier that you want the software to use for calculating the bend diameter.
BendAng1
Type the maximum number of degrees allowed for the first bend angle when associated with NumMiters1, or the corresponding default number of miters for angles. An example is 60 degrees.
BendAng2
Type the maximum number of degrees allowed for the second bend angle when associated with NumMiters2, or the corresponding default number of miters for angles. An example is 60 degrees.
BendAng3
Type the maximum number of degrees allowed for the third bend angle when associated with NumMiters3, or the corresponding default number of miters for angles. An example is 60 degrees.
NumMiters1
Type the number of miter cuts required for angles in the first mitered elbow.
NumMiters2
Type the number of miter cuts required for angles in the second mitered elbow.
NumMiters3
Type the number of miter cuts required for angles in the third mitered elbow.
RectDWRatio
Specify the ratio of the depth to the width of the rectangular cross section.
OvalDWRatio
Specify the ratio of the depth to the width of the oval cross section.
MinstraightLength
Type the minimum length to allow for a straight feature.
MaterialType
Type the material type for the HVAC component. Examples are CarbonSteel, CastIron or Concrete. The combination of the values in the MaterialType and MaterialGrade columns must be unique.
MaterialGrade
Type the material grade for the HVAC component. Examples are Fine, Annealed, or Tempered. The combination of the values in the MaterialType and MaterialGrade columns must be unique.
Thickness
Type a value for the thickness measurement for the duct material.
Tightness
Type a value for to indicate the water-tightness of the HVAC duct.
