You want to know what the product key for your Autodesk® Revit® 2011-based product is.

Autodesk's 2011-based software requires both a serial number and product key to successfully activate.

Product keys are used to differentiate software sold on its own from those sold as part of a suite. Ensure that you select the correct product key in order to successfully activate your software.

The product key is provided along with your serial number in the following places:

• If you received physical media, the product key is on the reverse of the package along with the serial number.
• Emails from Electronic Fulfillment notifying you of your new serial number also include the product key.
• Contract administrators can log on to Subscription Center to check for their serial number and product key.
• The Autodesk Business Center (ABC) can provide this information. Their toll-free number is 800-538-6401.

Revit 2011-based Product Keys:

• 240C1 - Revit Architecture 2011
• 241C1 - AutoCAD Revit Architecture Suite 2011
• 595C1 - AutoCAD Revit Architecture Visualization Suite 2011
• 255C1 - Revit Structure 2011

Pressure Drop Calculation

From: Revit MEP

I got an call from a client last week asking about some of the calculations that Revit MEP does.

I am trying to get results for Duct Pressure drop in Revit MEP.



Can you please share your ideas, as how can I achieve this?

This post has some additional information but is based on the Revit MEP calculation white paper from Autodesk. Revit MEP Duct Sizing calculations

Revit MEP computes pressure losses in ductwork based on the geometry and roughness of the ductwork, air

density, and air viscosity. Values for Air Density and Air Viscosity are specified in the Mechanical Settings.

Roughness is specified in the type properties for duct/duct fitting component families.

The following example shows how Revit MEP calculates the pressure drop for a 100 foot segment of 36"x24" duct carrying air flow of 12,000 CFM. Pressure drop is defined as:

This values checks with the Hydraulic Diameter parameter shown in the Properties of the Duct in Revit:

The velocity is based on the cross sectional area:

After determining the friction factor, the pressure drop can be calculated:

The value for the calculated pressure drop matches the value found in the duct’s properties in Revit MEP.

Worksets, Links & Filters in Revit 2011

Worksets, Links & Filters in Revit 2011

In Revit 2011 view filters now work across linked Revit files. This allows additional flexibility when creating view filters for the project.

Along with this, Revit can now read the worksets through a linked file. This is great to control visibility of a workset in a link, or to use in conjunction with a view filter.

One item to keep in mind is when you create a view filter, which is filtering by workset, the workset in the linked file will be read. So if you have your Revit link placed on a specific workset in the host project, Revit actually looks inside the linked project for each individual elements workset.

Example scenario is as follows…

1. You have 3 linked models; LinkA, LinkB & LinkC.

2. Each link is on a unique workset in the host project; LinkA, LinkB & LinkC.

3. You wish to create a view filter to override the color of the display for the entire link.

4. Because Revit is looking into the linked file, it will not see the workset assignment of the overall link for filtering purposes. Instead elements on a given workset, in the linked model, will be filtered according to the view filter in the host project.

If you would rather override the color of the entire link instance, you can navigate to Properties > Visibility/Graphic Overrides > Revit Links > Display Settings > Custom > Model Categories.

You can select all of the model categories at once with the SHIFT key, and apply a surface pattern / color as needed.

This will override the link display similar to the example image below:

Hope this helps!
