CreateMapped Method (View, IList(XYZ), IList(XYZ), IList(PathOfTravelCalculationStatus))

Creates multiple new paths of travel by mapping each of a set of start points to each of a set of end points and provides creation result statuses.

Namespace: Autodesk.Revit.DB.Analysis
Assembly: RevitAPI (in RevitAPI.dll) Version: 20.0.0.0 (20.0.0.377)
Since: 2020

Syntax

C# 
public static IList<PathOfTravel> CreateMapped(
	View DBView,
	IList<XYZ> pathStarts,
	IList<XYZ> pathEnds,
	out IList<PathOfTravelCalculationStatus> resultStatus
)
Visual Basic 
Public Shared Function CreateMapped ( _
	DBView As View, _
	pathStarts As IList(Of XYZ), _
	pathEnds As IList(Of XYZ), _
	<OutAttribute> ByRef resultStatus As IList(Of PathOfTravelCalculationStatus) _
) As IList(Of PathOfTravel)
Visual C++ 
public:
static IList<PathOfTravel^>^ CreateMapped(
	View^ DBView, 
	IList<XYZ^>^ pathStarts, 
	IList<XYZ^>^ pathEnds, 
	[OutAttribute] IList<PathOfTravelCalculationStatus>^% resultStatus
)

Parameters

DBView
Type: Autodesk.Revit.DB View
The floor plan view to use when computing the shortest distance.
pathStarts
Type: System.Collections.Generic IList XYZ
The start points of the path. The Z coordinates are ignored.
pathEnds
Type: System.Collections.Generic IList XYZ
The end points of the path. The Z coordinates are ignored.
resultStatus
Type: System.Collections.Generic IList PathOfTravelCalculationStatus %
Result statuses of each path of travel creation. The order of statuses corresponds to the order of elements in the array returned by the function.

Return Value

The array of newly created path of travel elements, or a null reference ( Nothing in Visual Basic) if no path between the two points is found. The number of elements is the number of start points multiplied by the number of end points. The order of elements corresponds to the order of end and then start points in the argument arrays: s0->e0, s1->e0, ... , s0->e1, s1->e1... etc. There are some additional conditions that are checked and if any condition is true the a null reference ( Nothing in Visual Basic) value is returned:
  • View has crop box active and start or end point lies outside of the crop
  • Start and end points are too close

Remarks

InvalidOperationException is thrown if PathOfTravel cannot be created for the following conditions:
  • View has crop box active and crop box is split
  • View model outline area is larger than the current limit (2,000,000 sq.ft.)
  • View export contains too much geometry (more than 200,000 lines)
ArgumentException exception is thrown if arrays of start or end points are of zero size or if the total number of paths of travel attempted to be created is more than maximum allowed (50000).

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException View is not in a family or a document in in-place edit mode. -or- View is not a floor plan view.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions InvalidOperationException The document containing DBView is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- This operation cannot be performed while the document is in edit mode. -or- The Path of Travel calculation service is not available
Autodesk.Revit.Exceptions ModificationForbiddenException The document containing DBView is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document containing DBView is being loaded, or is in the midst of another sensitive process.
Autodesk.Revit.Exceptions ModificationOutsideTransactionException The document containing DBView has no open transaction.
