Export Method (IList(ElementId))

Exports a collection of 3-D views

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 18.0.0.0 (18.0.0.420)
Since: 2014

Syntax

C# 
public void Export(
	IList<ElementId> viewIds
)
Visual Basic 
Public Sub Export ( _
	viewIds As IList(Of ElementId) _
)
Visual C++ 
public:
void Export(
	IList<ElementId^>^ viewIds
)

Parameters

viewIds
Type: System.Collections.Generic IList ElementId
An array of 3-D views to export

Remarks

Note that the actual export process may differ depending on the type of export context used. For example, when the IModelExportContext is used, Revit is likely to perform several rounds of traversing each view, which may result in invoking the OnViewBegin/OnViewEnd method multiple times for every one view. It is because Revit draws objects in several layers (model layer, annotation layer, etc.) and will traverse each layer individually. In the most common scenario the user will receive two invocations of OnViewBegin/OnViewEnd: In the first round, all model entities will be received, while in the second round all text annotation elements will be received, if any present in the given view.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException One or more elements in viewIds is not a valid 3D view. For example, templates are not considered valid views to export.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions InvalidOperationException The instance of IExportContext is not valid. -or- Rendering is currently not supported in the running instance of Revit. One reason for that to happen is that rendering and material libraries are not currently available.
