There are quite a few different content ‘standards’ being bandied about lately, from ANZRS to the Revit Model Content Style Guide.

There is a partial list of these content standards at the page below:

scientific investigation demands repeatability of results that can only be achieved by sharing of experimental models. A common set of building models could reduce the time required for researcher data collection and facilitate associated research and education.

Model 1. The Duplex Apartment Model (release 2.0)

The duplex apartment model was originally created by a student who developed this building as part of a design competition. This model was first used at the Dec 2009 COBie Challenge event. The model provided here is the second version of this model completed by designers at Kristine Fallon and Associates.


Model 2. Office Building Model

The two story office building model was developed based on the published sample floor plans for a specific type of mid-size office building built in the United States.


Model 3. Clinic Building Model

The Clinic Model was developed based on an actual federal medical and dental clinic building at a location in the South-West United States. The model also comes with a set of redacted design drawings. A full set of operations and maintenance manuals are also available but have not yet been redacted, so cannot yet, be posted to this public repository.

Jose doesn’t seem to think they are super-important:

Outside of Revit there are tools for managing and finding families that are more powerful and faster than any naming convention would ever allow anyone to do. And these tools have only started showing up. I’m certain that within a year there will be more options available than published naming standards.

Inside of Revit things could quickly change as well. I don’t have any specific knowledge of how or if Autodesk plans to sort out the challenges of finding families within the project browser (and if I did, I wouldn’t be able to tell you), but anyone can see that the current solution is sub-par. An improvement could come as soon as within a few months.

And Jose, I certainly agree that ‘the current solution is sub-par…’

The review process for the NATSPEC National BIM Guide has been completed and it is now available for use.
Learn more about the project or download the NATSPEC National BIM Guide document set v1.0. [390 KB]
The associated NATSPEC BIM Object/Element Matrix can be downloaded separately here. [4 MB]

NATSPEC is a specification framework that is widely used here in Australia.  I received an email from Mark Cronin today that alerted me to the significant number of BIM related resources they have developed or facilited.

The main portal link is:

On the projects page you can find links to a number of other resources, such as:
NATSPEC BIM Scheduling project
Start date: 2010 Status: Complete
NATSPEC undertook this project as an initial response to subscribers’ requests to develop a standardised Australian practice for the exchange of digital building information. The goal of the project is to recommend a consistent, systematic approach to allocating properties to BIM objects to facilitate the generation of useful schedules.
View pages about the project
or download the project report.

Further information on BIM scheduling can be found at the Resources page

buildingSMART BIM survey
Start date: 2010 Status: Complete
NATSPEC hosted a survey on current patterns of use of BIM in Australia as part of the economic study commissioned by the Australian Government’s Built Environment Industry Innovation Council (BEIIC) to examine the potential for BIM to improve the productivity of the building sector. (See BEIIC BIM Economic study.)
See a summary of the survey results in Chapter 5 of the BEIIC study report

Thanks again to Mark Cronin for the heads-up on this one!

For instance, there are links to multiple different ‘standards’ and guides.  A few are listed below:

A process for seamless, efficient, reproducible exchange of accurate and reliable that is widely and routinely utilized among all tools and stakeholders.
Online and print magazine covering AEC, MCAD, and GIS
The reading room for computer aided design
This twice-yearly publication provides articles of interest to the community. A live version with web content is being planned to augment the current product.
Presentation by Howard Ashcraft, Hanson Bridget and Dennis Sheldon, Gehry Technologies
These documents define how data is represented, shared, and managed between the myriad of software applications used in the structural steelwork industry.

Watch this page – pretty soon, the Australian and New Zealand Revit Standards (ANZRS) will be available for download…

The ANZRS document pack is not yet available for download. It will be made available within 2 weeks subsequent to its launch at the 2011 Australasian Revit Technology Conference, 26-28 May at Jupiters Gold Coast. Please come to the launch and/or revisit this page after that time.

Interesting undertaking to develop a new RFO Style Guide (RFOSG), to enhance the possibility of sharing content – over at the Revit Forum.

Here is the latest PDF version:
Revit Style Guide v0.2 pdf

And here is a sample of some of the contents:
Naming Conventions     4
Separators and Case     4
System Families     4
Loadable Families     5
Materials     7
Fill Patterns (Surface)     8
Fill Patterns (Cut)     8
Line Patterns     9
Line Styles     9
Line Weights     9
Text Styles     9

It is also in a nice ‘open’ format:
