Namespace: Autodesk.Revit.DB.Mechanical
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

The MEPSection type exposes the following members.

Name | Description | |
---|---|---|
![]() | FixtureUnit | The fixture unit of the section. |
![]() | Flow | The flow of the section. |
![]() | Friction | The friction of the section. |
![]() | FrictionFactor | The friction factor of the section. |
![]() | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. |
![]() | Number | The Section number. |
![]() | ReynoldsNumber | The Reynolds number of the section. |
![]() | Roughness | The roughness of the section. |
![]() | TotalCoefficient | The loss coefficient of the section. |
![]() | TotalCurveLength | The total length of all segments in the section. |
![]() | TotalPressureLoss | The total pressure loss of the section. |
![]() | Velocity | The velocity of the section. |
![]() | VelocityPressure | The velocity pressure of the section. |

Name | Description | |
---|---|---|
![]() | Dispose | Releases all resources used by the MEPSection |
![]() | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object ) |
![]() | GetCoefficient | Gets the loss coefficient for the specified element id in this section. |
![]() | GetElementIds | Gets all element ids that are contained in the section. |
![]() | GetHashCode | Serves as the default hash function. (Inherited from Object ) |
![]() | GetPressureDrop | Gets the pressure drop for the specified element id in this section. |
![]() | GetSegmentLength | Get the length for the specified segment id in this section. |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object ) |
![]() | IsMain | Check whether the type of fitting in this section is main. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object ) |

This is the base class for duct and pipe section. This class is mainly for pressure loss calculation. It is a series of connected elements (segments - ducts or pipes, fittings, terminals and accessories). All section members should have same flow analysis properties: Flow, Size, Velocity, Friction and Roughness. One section member element which contains more than one connector can belongs to multiple section. e.g.: One Tee which has 3 connectors, usually, it belongs 3 sections. One segment which connect to a tap will be divided into 2 sections.
