Autodesk Revit Format Attributes (Feature Representation)

Revit represents building models with three types of elements, known as

  • Model elements,
  • Datum elements, and
  • View-specific elements.

Please see the Autodesk Revit documentation for additional details.

Note  FME reads model elements as features, with information about related datum elements as attributes. View-specific elements, such as annotations, are read along with model elements in floor plan reading mode.

Line Weight tables

The Line Weight table features will contain several list attributes, each representing a column in their corresponding table. For the Model Line Weights table feature, these list attributes will be named after the scale of the corresponding column (for example a column with scale 1” = 1’0” will have an attribute 1:12). The values of these attributes are the entries in the corresponding table. Using our example from before, 1:12{0} will be set to the value in the first row in the 1” = 1’0” column, 1:12{1} will be the second, and so on.

Since there is only one column in both the Perspective Line Weight table and the Annotation Line Weight table, the features representing them will only have one list attribute named Line Weights.

If the element is a sub-component, this attribute will be set with the ObjectId of its parent component.

UniqueId

The unique ID of the feature. This ID is consistent for the lifetime of the element, even across multiple file sync operations.

WorksetName

If the element belongs to a workset, this attribute will be set to the name of the workset that the element belongs to.

BUILDING_LEVEL Field Attributes

These attributes contain information relating to the level of a building on which the feature is found. Stair (and some other) elements have two sets of these attributes: one for the level at their bottom (BaseLevel), and one for the level at their top (TopLevel).

Attribute/Trait Name

Contents

BuildingLevel

The level of the building that the feature is located on.

BuildingLevelElevation

The elevation of the feature’s building level.

BuildingLevelIsStory

The level that the feature is on is a building story.

BuildingLevelRoomOffset

The room offset of the feature.

Hosted Element Attributes

Elements that are hosted inside of other elements, such as doors, will have these additional attributes on their features.

Attribute/Trait Name

Contents

HostId

The ObjectId of a feature’s host element.

HostFeatureType

The feature type of a feature’s host element.

HostObjectFunction

The function of a feature’s host element.

Additional Parameters as Attributes

Additional built-in parameters will be read as attributes on features if they have been set on the corresponding Revit elements. These attributes are prefixed by their parameter set name, if applicable.

Attribute/Trait Name

Contents

Elevation

The elevation of this instance of the feature.

PointElevation

The elevation point of this feature.

Additional Parameters as Attributes for Piping Discipline Features

These parameters can be found on features from the piping discipline only.

Attribute/Trait Name

Contents

CalculatedSize

The calculated size of the feature.

Drain

The drain for this feature.

SupplyFitting

Whether this feature is a supply fitting.

SupplyPipe

Whether this feature is a supply pipe.

Trap

The trap for this feature.

WidthDiameter

The diameter of the feature.

Sub-attributes for Features with Connectors

Duct, electrical, pipe, cable tray and conduit elements have connectors to other elements of the same kind. These connectors are displayed as a list with several sub-attributes.

Attribute/Trait Name

Contents

DomainType

Which domain this connector falls under.

FlowDirectionType

The flow direction of this connector on the feature.

IsConnected

Whether this connector is connected to another connector logically.

IsPhysicalConnector

Whether this connector is connected to another connector and is visible in Revit.

Type

The type of connector on the feature.

User-Defined Parameters as Attributes

Family, Project, and Shared Parameters

FME will read family, project, and shared parameters from Revit elements as attributes on features if they belong to a supported parameter set. These parameter sets include:

  • Text
  • Title
  • Identity Data
  • Data
  • General
  • IFC
  • Phasing
  • Dimensions
  • Graphics
  • Analytical Properties
  • Electrical
  • Mechanical
  • Structural
  • Plumbing
  • Construction
  • Green Building
  • Constraints
  • Other

The parameters will be prefixed with the name of their set, similar to built-in parameters.

Schedule Parameters

FME will read schedule values as attributes on features. If an element belongs to a schedule, FME will attempt to read each column in that schedule and set attributes of the form <schedulename>.<columnname>. Note that not all column types are supported at this time.
