Boundary |
Indicates if the given curve loops compose a valid boundary on the view's detail sketch plane.
Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax
public static bool IsValidBoundaryOnView( Document document, ElementId viewId, IList<CurveLoop> curveLoops )
Public Shared Function IsValidBoundaryOnView ( document As Document, viewId As ElementId, curveLoops As IList(Of CurveLoop) ) As Boolean
public: static bool IsValidBoundaryOnView( Document^ document, ElementId^ viewId, IList<CurveLoop^>^ curveLoops )
static member IsValidBoundaryOnView : document : Document * viewId : ElementId * curveLoops : IList<CurveLoop> -> bool
Parameters
- document Document
- The document.
- viewId ElementId
- The view Id.
- curveLoops IListCurveLoop
- The curve loops to be checked.
Return Value
BooleanTrue if the given curve loops are valid as described above, false otherwise.

Exception | Condition |
---|---|
ArgumentNullException | A non-optional argument was null |

The curve loops are valid if projections of the loops onto the views's detail sketch plane do not intersect each other;
each curve loop is closed; input curves do not contain any helical curve;
and each loop is planar and lies on a plane parallel to the views's detail sketch plane, but not necessarily the same plane.
