PathOfTravel.FindShortestPaths

Method

Description:
For a floor plan view, calculates paths from each start point to its closest destinations. Returns the path, represented by an array of XYZ points.

Remarks:
The calculation is done in a floor plan with one or more destinationPoints and one or more startPoints. The shortest path is calculated from each start point to its closest destination point.

Syntax

public static IList<IList<XYZ>> FindShortestPaths(
	View DBView,
	IList<XYZ> destinationPoints,
	IList<XYZ> startPoints
)

Public Shared Function FindShortestPaths ( 
	DBView As View,
	destinationPoints As IList(Of XYZ),
	startPoints As IList(Of XYZ)
) As IList(Of IList(Of XYZ))

public:
static IList<IList<XYZ^>^>^ FindShortestPaths(
	View^ DBView, 
	IList<XYZ^>^ destinationPoints, 
	IList<XYZ^>^ startPoints
)

static member FindShortestPaths : 
        DBView : View * 
        destinationPoints : IList<XYZ> * 
        startPoints : IList<XYZ> -> IList<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.
startPoints	IList	Start points for which shortest paths are calculated.

Return Value

Type	Description
IList	Array of paths calculated from each start point to its corresponding closest destination. If a path cannot be caculated the corresponsing sub-array is set to an empty array.

Exceptions

Exception	Condition
ArgumentException	View is not a floor plan view.
ArgumentNullException	A non-optional argument was null
InvalidOperationException	The Path of Travel calculation service is not available -or- This functionality is not available in Revit LT.
