Autodesk Revit Architecture 2013 Enhancements 
- Improves stability when closing a sketch editor, such as slab, site, etc., which create a large number of points. 
- Improves creation of U-shaped winder stairs. 
- Improves stability when editing winder stairs.
- Improves performance when many railings exist within a project.
- Improves stability when support type is not defined for stair. 
- Improves railing representation in coarse view.

Autodesk Revit Structure 2013 Enhancements 
- Improves placement of analytical nodes when in 3D views. 
- Improves stability when enabling “Show Analytical Model Categories in this View” when the Warning dialog is open.
- Improves creation consistency with Physical Wall when coping an Analytical Model Wall.
- Improves stability when editing an Opening within an object which spans to the boundary of an Analytical Surface.
- Corrects the reporting of the “Structural Parameter” on slabs.
- Improves masking of linked files by Mask and Filled regions in Structural Views.
- Improves stability when placing Rebar.
- Improves stability when copying Area or Path reinforcement between projects which have differing value for the Reinforcement Project Setting: “Host structural rebar”. 
- Improves visibility of round rebar when displayed in fine detail level.
Autodesk® Revit® MEP 2013 Enhancements
- Corrects the Slope value on placeholder pipe when slope is greater than 15 degrees. 
- Improves consistency when applying a slope to a layout which contains a transition. 
- Improves stability when splitting pipes which belong to different systems. 
- Corrects visibility of the center line when displaying rise/drop symbols.
- Improves stability when opening a Revit 2012 project which contains a pipe placeholder schedule. 
- Improves consistency of unit formatting within Panel Schedules .
- Improves consistency of adding circuits to equipment that are connected to a pipe or duct system.
- Improves stability when adding a device, which is connected to a wire, to a circuit.
- Improves display of annotation on duct and pipe transitions. 
- Improves stability when inserting duct fittings. 
- Improves stability when viewing Routing Solutions.

There are also several Autodesk Revit API 2013 Enhancements:
- Allows Document.PostFailure to be used to post multiple errors during a single transaction that do not reference an ElementId.
- Improves stability using UIApplication.DoDragDrop when a Revit command (such as the Wall tool) was active.
- Improves stability by disabling keyboard shortcuts (except view zoom shortcuts) when a PreviewControl is active.
- Improves stability in ReferenceIntersector.FindNearest() when no matching target pick is found.
- Corrects validation logic to allow NewFamilyInstance to place face-based families on transformed family instances.
- Dimension.Above and Dimension.Below now update the dimension after their data is changed without requiring any user action.
- The properties MechanicalSystem.SystemType, ElectricalConnector.SystemType,
PipeConnector.SystemType are obsolete in Revit 2013. Instead query the parameter
RBS_DUCT_CONNECTOR_SYSTEM_CLASSIFICATION_PARAM on ConnectorElement.
- Corrects data reported with ConnectorManager.UnusedConnectors.
- Fixes a file corruption that could occur when extensible storage data was added to an element in a central file.
- Improves stability when saving a file with extensible storage data that overwrites an existing file that also contains extensible storage.
- RVT Links created with RevitLinkType.Create will remain loaded when the RVT containing the link is reopened.
- Previously, setting 'suppressBendRadius' to true in method Rebar.GetCenterlineCurves() would cause both fillet bends and user-drawn, parameterized arcs to be omitted from the collection of curves returned by the method.  The method now omits only the fillet bends; the drawn arcs are included along with the straight edges.
- Updates Rebar.GetCenterlineCurves() method with an additional argument: a MultiplanarOption (enum), which should be set to IncludeAllMultiplanarCurves or IncludeOnlyPlanarCurves.  This argument controls whether all curves of a multi-planar Rebar instance are returned, or only those which lie in the primary plane.
- Enables method Rebar.ComputeDrivingCurves().  This method returns a collection of curves that includes the lines and arcs that drive the shape, but excludes fillets and hooks.  It is equivalent to calling GetCenterlinCurves(adjustForSelfIntersection=false, suppressHooks=true,  suppressBendRadius=true, multiplanarOption=IncludeOnlyPlanarCurves)
- Improvements have been made in RebarShape methods that deal with matching RebarShapes to collections of curves: CreateFromCurvesAndShape(), RebarShapeMatchesCurvesAndHooks().
- Corrects behavior ot RebarShape.Create() method to not ignore the out-of-plane bend diameter specified in the RebarShapeMultiplanarDefinition argument object, and always used an internal
default value.
