In AutoCAD MEP, although many windows have been migrated to the Properties Palette (such as PipeAdd), some still remain, such as the DuctAdd window. If you are using Vista, you may have noticed that the 'Pin' control on these windows (which allows the windows to auto-hide) is not visible due to the Vista themes... however, if you right-click on the title of the window, there is an 'Enable Rollup' option that will accomplish the same thing.
New RDB Link Tool for Revit Family Available on Autodesk Labs!
Check out the new RDB Link Tool! The RDB Link tool enables you to export data from the elements in a Revit project and maintain relationships against data that exists outside of Revit. The tool allows for both import and export of the project data and will allow the user to make changes on the database side that affect the data within the project once imported. Learn more by visiting Autodesk Labs and downloading today!

Did you know that you can now change the display of centerlines for all round elbows in AutoCAD MEP 2010? The new command is “DisplayStraightCenterlines”
You can independently control the setup for Conduit, Duct and Pipe or set all of them to the same setting.
Centerline display for elbows. Select domain to change setting
[Conduit/Duct/Pipe/All]:
The settings are saved in the drawing so if your company prefers the centerlines on Elbows to show as intersecting make the change in the Templates.
this image shows the different displays of Piping, but all other round elbows will look like this also.
If you’ve been calculating heating and cooling loads in Revit MEP 2010, you may have wondered how the new Building Service parameter affects the analysis.
Heating and cooling load calculations are affected by variables that are extrapolated from the Building Service type. The most important variable is the Calculation Type, which is set to either Constant Volume, Variable Air Volume, or Radiant.
Most of the building service types are Constant Air Volume or Radiant (almost the same). The Variable Air Volume types include the acronym “VAV” in their naming convention.
There are also smaller characteristics determined by the service type, such as whether Use Reheat or the Fan Configuration (Blow Through or Draw Through) is used. These inputs help determine some of the zone-specific loads. Currently all of the service types use draw-through as the fan configuration.
The following table indicates the Building Service type variables that affect the heating/cooling load calculations.

In AutoCAD MEP 2009, we made some changes to how electrical panel schedules are created. In prior releases, the panel schedules were generated by VBA code and were difficult to customize. They are now based on AutoCAD tables and users can create their own schedule "templates" to match their company standards. You can even bring in an existing Microsoft Excel schedule to speed up the creation process.
We have published a white paper which explains in more detail how to create your own custom panel schedules. Link to whitepaper: AutoCAD MEP Panel Schedule Whitepaper

You can now download the Revit MEP 2010 Families Guide. Some highlights in this year's guide:
The Family Editor overview and concept chapters now contain more MEP-specific examples.
The tutorial exercises include more background information to explain why you are performing certain Revit-specific operations.
The tutorial exercises also include more images that make it easier for you to see where to click when performing a step. Other images have been added to show you the desired outcome of the step.
I'd like to start by thanking Kyle for his previous efforts in running this blog. I'm not sure that my writing style is as flavorful as Kyle's but I hope that I can help effectively manage this blog going forward. I'll start by introducing myself.
My name is David Pothier and I'm the new Product Manager for Revit MEP. Although new to this position, I'm not new to Autodesk, MEP or Revit. I started my MEP career working for a small consulting engineering company in Harrisville NH where I was lucky enough to build my MEP skills as well as learn AutoCAD. After 4 years working there, I went over to the dark side (yes, I'm a Star Wars fan) and started working for a software company called DCA Engineering which then became DCA Softdesk and then Softdesk before being acquired by Autodesk just over 12 years ago.
Over the 19 years I have worked in the software business I have filled many roles. I have worked in product support and QA. I have done product design and even development where I was the primary developer for the plumbing software in Softdesk S8. I have worked with our sales channel as a partner recruiter but I have spent the majority of my time working as an Applications Engineer where I demonstrated our architecture and MEP solutions to thousands of customers across North America.
As the new Product Manager, I'm really excited by the opportunity to help make Revit MEP the software solution that everyone wants it to be.
You can expect regular posts on this blog going forward. However, unlike the past, this blog will now be used to provide information on all Autodesk's MEP solutions including AutoCAD MEP and Revit MEP. As Kyle mentioned, this isn't just me or Kyle contributing but the MEP team at Autodesk. You can expect tips and tricks, informational posts, industry news, etc. Our goal will be to start with a post each week on tuesdays and thursdays so be sure to check back often.
Thanks
Dave Pothier

Alright, let’s be honest, Inside the System’s been a bit quiet lately. Well, more than quiet *dodges tumbleweed*. That’s going to change in a major way starting today, and we’re pretty excited about it. Today marks the re-launch on Inside the System, but under a different, broader mission. That mission is:
Mission: Possible
We have a broad set of solutions at Autodesk that address the needs of the Building Services Industry (aka MEP), and Inside the System serves as a conduit between Autodesk and the industry. Through this conduit, we seek to provide insight into our solutions, the industries they serve, and the customers that use them.
This is no longer an effort driven primarily by myself and others in Product Management, but rather the entire Product Team. This means that you will be hearing from a variety of folks across different functional groups, each bringing a different perspective and area of expertise. We think this will be the best way to communicate with all of you, and provide the information you need to be successful with our solutions.
So, without further ado, let’s get the ball rolling with some MEP-related goodness!
