Namespace: Autodesk.Revit.DB Class: FilledRegion

FilledRegion.CreateMaskingRegion(Document, ElementId, IList<CurveLoop>)

Method

Description:
Creates a view-specific masking region from the given boundaries.

Remarks:
View-specific masking regions can be created in models and 2d families. The line style of the boundaries will be set to thin lines by default.

Parameters

Parameter	Type	Description
document	Document	The document in which to create the masking region.
viewId	ElementId	The view Id.
boundaries	IList	The boundaries.

Return Value

Type	Description
FilledRegion	The newly created masking region.

Exceptions

Exception	Condition
ArgumentException	The document is a 3d model family. -or- Details can't be drawn in the view. -or- Masking regions and Filled regions can't be created in this document or view. -or- The input curve loops cannot compose a valid boundary, that means: the "curveLoops" collection is empty; or some curve loops intersect with each other; or each curve loop is not closed individually; or each curve loop is not planar; or each curve loop is not in a plane parallel to the view's detail sketch plane; or input curves contain at least one helical curve. -or- Thrown if the viewId is invalid, or the view does not support the detail items creation, or if the boundaries are empty, open, or self-intersecting.
ArgumentNullException	A non-optional argument was null
