Using Revit as a Team. Use Same Builds.

When using Revit on a project, make sure everyone on the team is using not only the same version, (2011, 2012, etc), but the same build number as well.  The build number can be found by clicking on the question mark pull down in the upper right corner, and click the About button….

From there, you’ll see the splash screen of the version, and the build.  The first 4 numbers in the year the build was released, (2010) The next 2 are the month of the release, (09-September), the next 2 are the day of the release, (03-third).  The last four are the actual build number 2115, and the service pack number is new to the newer versions.  Might not be shown for earlier versions.


I’ve seen fatal errors in Revit when teams are using the same version, but different build numbers, and users are syncing their builds local file to the central file, and the central file is receiving updates from multiple builds, when there have been some changes to the software code, and there is a discrepancy  between two items, one new version, one old version, and Revit doesn’t know what to do. 

In order to make sure everyone is using the same build, everyone should be using the latest build.  For 2011, its build 20100903_2115 Web Update 2 Service Pack.  For 2012, it’s build 20110916_2132 Update Release 2.

Armacell Insulation Taking Advantage of Revit MEP 2012 Enhanced Insulation Objects

Designers and engineers who use Revit 2012 MEP building design software can add mechanical insulation to their designs with this Module.

Armacell's most popular insulating products are incorporated into the BIM Module:

  • AP Armaflex closed cell elastomeric foam insulation for piping components and ducts
  • AP Coilflex highly conformable, pliable elastomeric thermal ductliner
  • Tubolit flexible, closed-cell polyolefin/polyethylene pipe insulation for cost-efficient thermal insulation of domestic heating and plumbing lines
  • ArmaTuff thermal mechanical insulation with UV protection for outdoor applications
  • NH/Armaflex halogen free, flexible elastomeric insulation material for marine and offshore environments.
  • UT Solaflex EPDM thermal insulation for high temperature, UV-resistant and oil-resistant applications

Project Spark - A future Revit LT?

Project Spark is a technology preview of a new future Revit Architecture (BIM) solution. Using Project Spark, building professionals can create designs efficiently with real-world building objects, produce more reliable documentation faster, and share files with consultants using Revit or AutoCAD-based products.

Project Spark looks like a striped down version of Revit and does not support conceptual design, analysis, rendering, advanced collaboration, and API.  It may turn out to be a Revit LT version of sorts.  I would guess they would come out with all flavors of Revit, but they are only testing the architectural version.  MEP and Structural hopefully would be available when released.
Currently, you cannot open Revit Architecture or Revit MEP 2012 in Project Spark. Files created in Revit are not supported in Project Spark. However, Revit 2012 files can be linked into Project Spark.
You also cannot open Project Spark files in Revit Architecture or in Revit MEP 2012.  Because Project Spark uses a newer Revit file format, it is not currently possible to open files created in Project Spark with Revit 2012.

They're looking for feedback on the overall concept, usability, and learnability of the product.

You can download the preview here.

Revit MEP 2012 Update 2 – September 2011

In case you are too lazy to search to the Autodesk site... I've posted it here

Update 2 is not a full install; rather it is using service pack technology similar to AutoCAD®- based products. Update 1 is built into Update 2, so you don't need to worry about installing the first one before installing the second one.
Improvements made in Update 2 build (20110916_2132):

Autodesk® Revit® MEP 2012 Enhancements
  • Improves stability when routing ducts which utilize an elbow or takeoff to complete the run.
  • Improves stability when dragging a Panel Schedule into a sheet.
  • Corrects the classification of embedded windows within a curtain wall contained within a linked file which is used as the boundary to create spaces.
  • Improves the regeneration time of Ducts after applying a Visibility/Graphics Override.
  • Improves stability when creating a new zone in the zone editor and specifying an already existing name in the properties palette.
  • Improves performance when adding an air terminal to a system.
  • Retains System Type when coping elements from one project to another.
  • Retains pipe and fitting connections when moving piping layout to another level.
  • Improves the display of duct with insulation and lining for hidden line views when contained within a linked file.
  • Improves display of insulation on segments when viewed in ceiling plans.
  • Maintains the type parameter values for panel schedules viewed on a sheet.
  • Maintains circuits when upgrading Revit MEP 2011 projects in Revit MEP 2012.

Autodesk Revit® Platform 2012 Enhancements

  • Improves stability when switching the visibility setting of linked file from By Linked View to By Host View.
  • Corrects Ambient Shadow on objects which are contained within a mirrored linked file.
  • Improves the import of IFC files which contain overlapping walls.
  • Improves stability when exporting a project to DXF which contains a dimension style that is referenced more than 255 times within the project.
  • Corrects the resolution of the background image when calculating offset and scale.
  • Corrects duplicate column creation when using Create columns by Grid when some columns are already created on the grid.
  • Improves stability when setting a view to Realistic display mode.
  • Improves stability when navigating in 3D view after canceling a Print operation.
  • Corrects silhouette display for perspective views in projects with linked files.
  • Corrects the angle of Photometric Web based light sources when exported to FBX.
  • Retains the original IES files when exporting to FBX.
  • Reduces the scenarios where element IDs may become remapped or removed when Synchronizing to Central.
  • Improves stability when removing layers from floors, roofs and walls.
  • Corrects gbXML export of curtain walls where window openings were classified as air opening when using simple complexity mode.
  • Improves stability when accessing HELP
  • Help
  • Corrects mapping of Cable Tray, Cable Tray Fittings, Conduit and Conduit Fittings when exported to IFC.
  • Improves the consistency of beams being unique objects when exported to IFC.

Easily share your BIM with eTransmit for Revit

Here is a snippit from Autodesk Lab's website...

With eTransmit for Revit, you can:

  • Copy and detach a Revit model and associated files to a single folder for internet transmission. This removes the typical error messages when you copy central files using the operating system.
  • Locate dependent files automatically and include them in the transmittal folder, reducing the possibility of error. All dependent files are automatically converted to use relative paths to ensure that the dependent files can be located by the model.
  • Choose to include related dependent files such as linked Revit models, CAD files, DWF markups, decal images, and external keynote files. You can transmit any Revit (.rvt) model that has been upgraded to Revit Release 2012.
  • Transmit models that are using file-based worksharing or server-based worksharing. eTransmit for Revit will also work with non-workshared Revit models.

Common uses for eTransmit

  • Internal archiving
  • Sending deliverables to clients
  • Model exchange between consultants/partners
  • Model cleanup
  • Sharing models between disciplines


The technology preview will operate until December 31, 2011.
