The German Autodesk AEC team have put together a step by step tutorial on exporting a PAT file from AutoCAD and then importing it into Revit.

They have even shown how to correctly scale the imported PAT files numerically – rather than the haveAguessAndSee method that I generally use.

Steve Stafford tweeted a link to this thread. It shows the major milestones in Revit development, including company acquisitions, product renaming and discipline-specific additions.  For example, here are the release dates of the very early versions:
Revit Technology Corporation
1.0 2000 04
2.0 2000 08
2.1 2000 10
3.0 2001 02
3.1 2001 06
4.0 2001 11

In most cases the language barrier does not matter too much – you should be able to follow most of his workflow.  Here is a video of that Dubai building:

A while ago I posted about Trimble (Trimble Acquires Tekla)

Now, Trimble is developing plug-ins for various CAD softwares (including AutoCAD and Revit), which essentially will allow users to add ‘points’ to their models for easy export to the Trimble field surveying hardware.

SUNNYVALE, Calif., Sept. 27, 2011 /PRNewswire/ — Trimble (NASDAQ: TRMB) today announced updates to its Trimble® Point Creator software platform by introducing plug-ins for CAD and Autodesk® Revit® users. Existing users of Autodesk Revit 2012 (Architecture, MEP, and Structures versions) and popular CAD platforms, such as AutoCAD®, AutoCAD® MEP®, Bricscad, and ZWcad can operate natively within the Trimble Point Creator application to create 2D and 3D points. The points are then easily transferred to the Trimble LM80, Trimble MEP, and Trimble Field Link solutions for construction layout in the field.

If you want to be notified when these plug-ins are released, go to:

Check out the big list of BIM Resources at the following BIMtoField Page:

  • BIM Project Execution Planning Guide, Penn State – If you have time to read only one resource, this is the one. The Penn State team just released version 2.0 of the BIM Execution Plan in June 2010. This guide includes a complete outline of BIM implementation.
  • National institute of Building Sciences (NIBS) – Focused on gathering a number of organizations from government, professional, industry, labor and consumer interests. There are two projects that are of particular interest to the BIM community.
    • BuildingSMARTalliance – A council of the National Institute of Building Sciences and a driving force behind industry leading projects on a number of fronts.
