Revit MEP
When Duct Settings is selected, the right pane displays a set of parameters that are common to all the duct systems in a project. The Conversion branch below Duct Settings let you define default parameters that are applied separately to supply, return, and exhaust duct systems in your project.
Duct settings, duct sizes, and duct types can be copied to another project using the Transfer Project Standards feature.
The following parameters specify the default duct types, sizes, and settings:
- Use Annot. Scale for Single Line Fittings:
Specifies whether duct fittings are drawn at the size specified by the Duct Fitting Annotation Size parameter. Changing this setting does not change the plotted size of components already placed in a project.
- Duct Fitting Annotation Size:
Specifies the plotted size of fittings and accessories drawn in single-line views. This size is maintained regardless of the drawing scale.
- Air Density:
- Air Viscosity:
- Rectangular Duct Size Separator:
Specifies the symbol to be used in showing rectangular duct sizes. For example, when an x is used, a duct that is 12 inches high and 12 inches deep would be shown as 12” x 12”.
- Rectangular Duct Size Suffix:
Specifies the symbol appended to the duct size for rectangular ducts.
- Round Duct Size Suffix:
Specifies the symbol appended to the duct size for round ducts.
- Duct Connector Separator:
Specifies the symbol used to separate information between 2 different connectors.
- Oval Duct Size Separator:
Specifies the symbol to be used in showing oval duct sizes. For example, when an x is used, a duct that is 12 inches high and 12 inches deep would be shown as 12” x 12”.
- Oval Duct Size Suffix:
Specifies the symbol appended to the duct size for oval ducts.
Conversion
When Conversion is selected, you can specify the elbow angle increment and parameters used by routing solutions for both Main and Branch systems.
- Elbow Angle Increment:
The Elbow Angle Increment setting at this level is applied to both Main and Branch for all systems. The Elbow Angle Increment determines how the value of the angles for elbows will be used by routing solutions.
Branch
When Branch is selected, you can specify the following default parameters for the branch ducts in the each system type (Exhaust, Supply, Return):
- Duct Type:
This the default duct type for branch ductwork.
Offset:This is the height of duct components above the current level.
Flex Duct Type:This is the default type for flexible duct for branch ductwork (Flex Duct Round : Flex - Round, or None).
Maximum Flex Duct Length:This is the longest length of a flexible duct segment that can be used in routing solutions for branch ductwork.
Rectangular
When Rectangular is selected, the right panel lists rectangular duct sizes available for a project and shows which sizes can be specified from the Options Bar. Although only one value is used to specify duct size here, it can be applied to height, width, or both. The Delete Size button removes a selected size from the table. The New Size button opens the Duct Size dialog, where you can specify new duct size to be added to the project.
Oval
When Oval is selected, the right panel lists oval duct sizes available for a project and shows which sizes can be specified from the Options Bar. Although only one value is used to specify duct size here, it can be applied to height, width, or both. The Delete Size button removes a selected size from the table. The New Size button opens the Duct Size dialog, where you can specify new duct size to be added to the project.
Round
When Round is selected, the right panel lists round duct sizes available for a project and shows which sizes can be specified from the Options Bar. The Delete Size button removes a selected size from the table. The New Size button opens the Duct Size dialog, where you can specify new duct size to be added to the project.
You can select how size values will be used:
- Use in Size Lists:
When selected for a specific duct size, the size appears in lists throughout Revit, including duct layout editor, duct modify editor, flex duct and flex duct modify editor. When cleared, the size does not appear in these lists.
- Use in Sizing:
When selected for a specific duct size, Revit determines the duct size, based on calculated system air flow. When cleared, the size is not used by the sizing algorithm.
