Revit 2011 Web Update 1

Rather belatedly, I note that the first web update of Revit 2011 was released in the beginning of this month and can be downloaded from the public Revit product pages:

• Revit Architecture > Product Download
• Revit MEP > Product Download
• Revit Structure > Product Download

Here is the list of the API enhancements, which is the same across all three flavours:

• Elements will now be properly joined when the ExternalCommand concludes when using automatic regeneration and automatic transaction.
• ExportImage(ImageExportOptions) no longer throws an exception when given a set of views.
• ElementParameterFilters now operate properly against ElementType elements.
• Improves stability when saving a family and there are event subscribers for Save or Save As.
• Closes the Family editor environment after loading a family via the API.
• Improves stability when using selection APIs to pick grid elements.
• Dynamic Model Update: GetChangeTypeGeometry() now triggers properly when active type is changed.
• Improves stability for Dynamic Model Update: when registering updaters and more than one application is registered.
• The new API SunAndShadowSettings.CalculateTimeZone() uses Revit’s mechanism to calculate the time zone value for a given latitude and longitude. This calculation is more accurate than the results obtained from City.TimeZone.
• Improves performance of display of Analysis Visualization framework when Hardware Acceleration is on.
• VSTA is now allowed for multiple concurrent sessions of Revit; editing the same module by two sessions is prohibited.
• VSTA: Document-level macros no longer become corrupted when the document is workshared and the macro is edited by more than one concurrent session.
• Improves stability when calls to NewFamilyDocument() and PickObjects() are used in sequence.
• VSTA: Revit no longer prematurely exits when opening a project containing corrupted macros.
• The Idling event no longer generates a journal comment for each invocation.
