A Room Calculation Point setting has been added to all family types that are room-aware, e.g., furniture, doors, casework, specialty equip, generic models. When these families are placed in a project, sometimes portions of their geometry are located outside a room, space, or within another element, which results in no calculable values being reported. Enabling the Room Calculation Point enables you to move the location of the calculation point to fall inside the required space.

The room calculation points also have to/from room functionality for doors so the you can better control how the door calculates which side is the To side and From side.

  In Summary:    You can improve design accuracy and ensure room/space calculations account for all elements for more accurate energy analysis.

When creating an instance project parameter (Text, Area, Volume, Currency, Mass Density, URL, Material, and <Family Type> only), you now have the option to allow the value to vary for different group instances. The user can edit the parameter value for an element in a group instance without changing the value for corresponding elements in other group instances.

  In Summary:   This features gives more flexible data reporting and increased support for COBie requirements.

Now in addition to energy analysis of conceptual massing elements, in Revit 2014 you can perform energy analysis using detailed Revit models. The building elements simulation option creates an Energy Analytical Model directly from your Revit building elements and sends it to Autodesk Green Building Studio for simulation using DOE2.2. Once the analysis is complete, you can review and compare results as you continue to iterate the model and inform your design decisions. 

This innovative new algorithm automatically identifies and places analytical spaces and surfaces and creates gbXML.

 This new feature works both with and without the placement of Revit room / space objects - thereby facilitating whole building energy simulation with (as little as) "one click".  The tool also accounts for more complex model geometry like sloped walls, varying wall thickness and plenum spaces.  There is no need to prepare the model for analysis or rebuild a separate model.

  In Summary:  You can conduct more reliable, repeatable whole building energy analysis with less time and skill.

Architects, MEP and structural engineers, and contractors can create exploded views of any 3D view, including perspectives.

Exploded views can be used to illustrate the relationship model elements have to the model as a whole. This information can be used in construction documents to show design intent . In any 3D view (including perspective), model elements can be moved by using the Displace Elements tool. You use this tool to create displacement sets and move them along their X, Y, and Z axes to a specified distance away from the model. Then, you can draw paths  that connect these elements back to their original model location.

 In Summary:  Visualize the building elements and how they are connected with the ability to create "exploded" 3D diagrams views.

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.

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) 

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, 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, you can select multiple detail items or imported raster images, and use the Send to Back, Send Backward, Bring to Front, or Bring Forward tools to move them all in one operation.

The second enhancement enables you to use the align tool on a divided surface in the Conceptual Massing Environment. You can align the UV grids on a planar divided surface by using a straight edge of the surface as a reference, or an external reference. This method enables you to rotate the grid to be aligned to the edges you select.

In Revit 2014, you can change a rectangular crop region or callout view to a non-rectangular shape.

When you select a crop region there are two new features available on the Modify| Structural Plan tab, on the Mode panel (Edit Crop and Reset Crop features).

Using the tools on the Modify and Draw panels you can edit the crop region as needed. You can modify the existing lines or delete the lines and sketch a completely different shape.
