Revit 2025 API
Path |
For a floor plan view, calculates the paths from each start point to its closest destination and return the path end points.
Namespace: Autodesk.Revit.DB.Analysis
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax
public static IList<XYZ> FindEndsOfShortestPaths( View DBView, IList<XYZ> destinationPoints, IList<XYZ> startPoints )
Public Shared Function FindEndsOfShortestPaths ( DBView As View, destinationPoints As IList(Of XYZ), startPoints As IList(Of XYZ) ) As IList(Of XYZ)
public: static IList<XYZ^>^ FindEndsOfShortestPaths( View^ DBView, IList<XYZ^>^ destinationPoints, IList<XYZ^>^ startPoints )
static member FindEndsOfShortestPaths : DBView : View * destinationPoints : IList<XYZ> * startPoints : IList<XYZ> -> IList<XYZ>
Parameters
- DBView View
- The floor plan view to use when computing the points.
- destinationPoints IListXYZ
- Destination points. The input Z coordinates are ignored and set to the view's level elevation.
- startPoints IListXYZ
- Start points for which shortest path end points are calculated.
Return Value
IListXYZEnd points of paths calculated from each start point to its corresponding closest destination. If a path cannot be calculated the corresponsing end point is set to the corresponding start point.
