Namespace: Autodesk.Revit.DB.Analysis Class: PathOfTravel

PathOfTravel.FindStartsOfLongestPathsFromRooms

Method

Description:
For a floor plan view, calculates paths from points inside rooms to the closests of the destinations. Returns the start points of the longest path(s). If multiple paths have the same longest length, returns multiple start points.

Remarks:
The entire plan is divided in small tiles, and the distance to the closest destination point is calculated for each tile center point. Only tile center points that are located in rooms in the view are taken into account.

Syntax

	View^ DBView, 
	IList<XYZ^>^ destinationPoints
)

        DBView : View * 
        destinationPoints : IList<XYZ> -> IList<XYZ>

Parameters

Parameter	Type	Description
DBView	View	The floor plan view to use when computing the points.
destinationPoints	IList	Destination points. The input Z coordinates are ignored and set to the view's level elevation.

Return Value

Type	Description
IList	Start points of the paths with longest lengths. The array is empty if there are no valid paths from any points in rooms to any of the destination points.

Exceptions

Exception	Condition
