Autodesk® Revit® MEP 2011 Update 1


Download is the latest update for Autodesk® Revit® MEP 2011 software as part of AutoCAD® Revit® MEP Suite 2011 software.  There are separate downloads for the 64 bit and 32 bit versions.

Update 1 is not a full install; rather it is using service pack technology similar to AutoCAD®- based products. Prior to installing the Update 1, please verify that you have already installed the First Customer Ship build of Autodesk Revit MEP 2011.  This is how Autodesk has been pushing updates out lately, which is different than in years past where you had to download and install a whole new build of the program. 

The service pack can be applied to both the standalone and suite versions of Autodesk Revit MEP 2011.  This is also different than in years past.  Autodesk used to have different downloads for the Revit MEP build and the Revit MEP Suite build.

For a list of improvements, please download the Autodesk® Revit® MEP 2011 Update Enhancement List: or see them below.

Revit MEP Alternatives to AutoCAD Procedures

Todd Shackelford just got an article published on Autodesk University's Tech Talk site. Check his article out by clicking the link in this sentence

It is safe to say that most MEP engineers who are trying to make the switch to Autodesk© Revit© MEP have arrived there by way of a DWG-based product. With years of refined processes in place, it can be difficult for established firms to find solid footing in unfamiliar software that seems to play by completely different rules. Finding ways to incorporate time-tested methods from the AutoCAD© days and improving them for use in Revit MEP can help make the difference between success and failure. The following example shows how Revit MEP can improve upon a layering trick that is used often in AutoCAD.

Places to Find Revit Content

Chris Mounts has created a list of places to get content. 

There has been a ongoing discussion thread on LinkedIn group Club Revit in which members have been sharing links to Revit content. Chris has summarized, sorted and combined the contents into a more usable list.

Pressure Drop Calculation

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.
