Syntax
The Alignment type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | Description | The Description of this alignment. |
| DisplayedEndStation | Specifies the station at which the alignment's display ends, in Revit internal model units (standard Imperial feet). |
| DisplayedStartStation | Specifies the station at which the alignment's display starts, in Revit internal model units (standard Imperial feet). |
| Element | The underlying DirectShape element. |
| EndStation | Specifies the station at which the alignment's geometric definition ends, in Revit internal model units (standard Imperial feet). |
| GUID | The GUID of this alignment. |
| Name | The Name of this alignment. |
| StartStation | Specifies the station at which the alignment's geometric definition starts, in Revit internal model units (standard Imperial feet). |
Methods| Name | Description | |
|---|---|---|
 | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Get(Element) | Returns an Alignment object given a Revit alignment element. |
| Get(Document, Guid) | Returns an Alignment in the document given its GUID. |
| GetAlignments(Document) | Returns all alignments in the given document. |
| GetAlignments(View) | Returns all alignments visible in the given view. |
| GetClosestPoint | Calculates the point on the alignment's geometry which is closest to the given model point. |
| GetClosestStation | Calculates the alignment station closest to the given model point. |
| GetDisplayedHorizontalCurveEndpoints | Returns the endpoints of the alignment's horizontal curves. Only the points between DisplayedStartStation and DisplayedEndStation are returned. |
| GetDistance | Calculates the relative distance along the alignment between two stations based on their alignment distances according to Revit Internal Origin Coordinate Base. The distance may be positive or negative depending on the relative positions of the input stations on the alignment. |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetHCurveNormalAtStation | Calculate 2d (X and Y components of returned vector) horizontal normal at given station. |
| GetHCurveTangentAtStation | Calculate 2d (X and Y components of returned vector) horizontal tangent at given station. |
| GetPointAtStation | Calculates the model point for a given alignment station. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| GetVCurveNormalAtStation | Calculate 2d (X and Y components of returned vector) vertical normal at given station. |
| GetVCurveTangentAtStation | Calculate 2d (X and Y components of returned vector) vertical tangent at given station. |
| IsValid | Checks if this object is a valid alignment. |
| IsValid(Element) | Checks if the element is a valid alignment. |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Remarks
The element is a DirectShape.
The element's category is OST_Alignments.
