PathOfTravel.FindShortestPaths

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.

Autodesk.Revit.DB.View

DBView

The floor plan view to use when computing the points.
IList<XYZ>

destinationPoints

Destination points. The input Z coordinates are ignored and set to the view's level elevation.
IList<XYZ>

startPoints

Start points for which shortest paths are calculated.

Return Value nullNothingnullptr 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 null Nothing nullptr a null reference ( Nothing in Visual Basic) .
