In Revit 2014, enhancements to the Material Browser dialog include:

The Material Editor functionality which has been integrated into the Material Browser dialog. To edit a material, select it in the Material Browser, and edit information in the tabs in the right pane, now referred to as the Material Editor panel.

There is an editable Materials Classification system to allow for rapid search within a Project or Library, in conjunction with the Breadcrumb UI element contained in the Material Browser and now you can assign, sort, and organize materials by class.

In Revit 2014, the following layer standards for exporting DWG and DXF files have been updated to reflect the latest changes.

• American Institute of Architects (AIA)
• ISO standard 13567
• Singapore standard 83
• British standard 1192

Also you can find import improvements for IFC, and DWG/DXF.
Textures, line patterns, line weights, and text are now included in 3D DWF exports.

When an imported instance containing 3D solid geometry is exploded in the Family Editor environment, the 3D solids are now preserved. Each 3D solid becomes a free form element, which can be used for cutting, joining, and other form operations. These free form elements can be edited by dragging the shape handles on planar faces.

In Revit 2014, the new user interface options enable you to configure the double-click behavior to edit Families, Sketched Elements, Views & Schedules on Sheets, Assemblies, Groups, and Component Stairs.

These default actions may be modified in Options -> User Interface -> Double-click options. In the Customize Double-click Settings dialog box you can specify double-click behavior for entering edit mode for the mentioned element types. Depending on the element type, you can choose to have double-click:

• Do nothing
• Enable editing of the element type properties
•  Enable editing of the element (or in the case of Views/Schedules on sheets, double-click can activate the view) 

Revit has previously enabled the following dialog windows to "dock" or "stick" to the left, right, top, and bottom of the Revit Application Window.

The following windows can be moved and resized, and either floated or docked:

•  Project Browser
• System Browser
• Properties palette
• Reconcile Hosting window

They can also be grouped so that several windows (represented by tabs) occupy the same space on the screen.

  In Summary:  Use tabs to work more efficiently with a familiar workflow for dialog windows.
