Create Method

Building Pad Create Method

Creates a new BuildingPad element and adds it to the document.

Namespace: Autodesk.Revit.DB.Architecture
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public static BuildingPad Create(
	Document document,
	ElementId buildingPadTypeId,
	ElementId levelId,
	IList<CurveLoop> curveLoops
)

Parameters

document Document
The document to be modified.
buildingPadTypeId ElementId
The type id set to the BuildingPad.
levelId ElementId
The level id set to the BuildingPad.
curveLoops IList CurveLoop
The boundary of the BuildingPad.

Return Value

BuildingPad
The new BuildingPad element.
Exceptions
Exception Condition
ArgumentException The buildingPadTypeId is not a valid type id for a BuildingPad. -or- The ElementId levelId is not a Level. -or- The input curve loops cannot compose a valid boundary, that means: no curve loop is contained in the given collection; these curve loops intersect with each other for some of them; 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 horizontal(XY) plane.
ArgumentNullException A non-optional argument was null
InvalidOperationException Failed to create the Sketch for the boundary of new created BuildingPad. -or- Cannot find an appropriate hosting topography surface for this BuildingPad. -or- This topography surface cannot be the host of this BuildingPad. -or- The given curve loops intersect with curve loops of existing BuildingPads hosted on the same TopographySurface. -or- There is at least one existing SubRegion which is completely inside or overlap the boundary of current BuildingPad hosted on the same TopographySurface. This behavior is not allowed.
ModificationForbiddenException The document 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 is being loaded, or is in the midst of another sensitive process.
ModificationOutsideTransactionException The document has no open transaction.
Remarks
The document will be regenerated during the creation of building pad element. If the input curve loops intersect the curve loops of existing BuildingPads hosted on the same topography surface, an InvalidOperationException will be thrown. If you need access to the topography surface created by the introduction of this building pad, you can obtain it from AssociatedTopographySurfaceId .
