Photometric lights and mental ray materials allow views to be rendered inside of Revit. Environment settings and entourage add life to the rendered scenes.
The first image was a precanned view but I added some light fixtures, and rendered the scene to be a night scene and adjusted some settings to show off the lighting.
The second image was already completed by Autodesk, and I just exported it out of the project. But these are just objects in Revit that have materials assigned to them, and light fixtures that have ies photometrics and light sources attached to them.
There isn't much for setting up of lights in the rendering proceedure. Other than the ability to turn some lights on and some lights off in light groups and you can also dim the light groups in Revit rendering. The lights will render as what they are in the family. Last is the Light Source Definition that is new in 2009. You can choose the shape and distribution that the light gives off. This and the IES photometric file can be used for both point-by-point analysis in 3rd party programs and for renderings in Revit MEP.

Content is very important to our business. In addition to the new content of last years content extension, which more than doubled the MEP components available for use in Revit MEP, a significant amount of new content has been added to the 2009 version:
- Commercial condensing units up to 130 tons
- Air-cooled and water-cooled vertical packaged systems up to 60 tons
- Horizontal and vertical belt-drive DX and CW fan coils, stacked fan coils, and ceiling-mounted fan coils
- Packaged air handlers up to 25 tons
- Gas-fired and electric commercial packaged rooftop units to 130 tons
- Down-flow, vertical, and horizontal high-efficiency water source heat pumps up to 20 tons
- Occupancy and daylighting sensors
- Consolidation of Revit Architecture light catalogs with Revit MEP catalogs
- Volumetric and direct-indirect lights.
You can support sustainable design efforts using Revit MEP 2009 by using built-in duct, pipe, and electrical sizing tools dynamically interact with the BIM and built-in heating and cooling load analysis tools to optimize system design for maximum efficiency and more accurately predict the performance of building systems. Export to gbXML (green building extensible markup language) and API (application programming interface) links allow industry-standard tools such as Integrated Environmental Solutions’
Sustainable design tools in AutoCAD Revit MEP Suite include:
- Duct sizing
- Pipe sizing
- Plumbing fixture unit sizing
- Electrical feeder sizing
- Panel schedule loads
- Heating/cooling loads
- Solar shading
- gbXML export to trace 700, IES
, and others
- API link to IES
- Intel Core™ 2 Duo, 2.4 GHz or equivalent AMD Athlon processor
- Windows XP Professional SP2 or later
- 4 GB RAM
- 4 GB disk space
- Dedicated video card with hardware support for OpenGL spec 1.3 or later
Revit MEP can be run immediately after downloading and installation in a fully functioning trial mode for 30 days. Upon first use of Revit MEP, a licensing wizard will be displayed. Select 'Run the product'. To later register the product, choose "Product and License Information" from the Help menu and follow the registration instructions in the following sections.
After Trial mode has expired, Revit MEP may still be used in Demo mode. In Demo mode you can open existing Revit files, view and print them and explore Revit MEP and all its functionalities prior to any purchase. However, if you create a model in demo mode or change an existing model, you will not be able to save or print those changes. In order to use Revit MEP in Demo mode select the Demo/Viewer radio button in "Product and License Information" dialog accessible from the Help menu.

If you change the view properties so it is displaying using a coordination disipline instead, the walls will become darker, and the piping will be hidden behind the wall objects. But it will not display the piping with hidden lines.
If you create plan views using Coordination disipline, you can see the pipe that goes through the wall or under a light fixture or another pipe as disappearing.
When in plan mode, and the view set to a mechanical disipline, you can see those pipes passing below other MEP objects as hidden lines, but not shown hidden through the wall objects as shown below.
To do this, you'd probably need to use a basic line tool for this. Perhaps there will be more control provided for this feature in the future. For now the above workaround may help.
