FW: Bluebeam compare PDF documents

Image
Bluebeam has a really nice feature to compare 2 pdf documents. Under the menu Document > Compare document, then select the PDFs to compare.

Bluebeam will highlight areas that have changed. It also scroll locks the view so as you pan and zoom – both views remain synchronized.




FW: BIM Buzz

Pretty good site for buzzwords- here are the ones I have run across the most: http://www.cdi-grp.net/BIM_Terminology.html
IFC – Industry Foundation Classes, is a data exchange method that specifies elements that are used in building construction in an agreed manner that define a common language for construction.  IFCs provide a foundation for the exchange and sharing of information directly between software applications of a shared building project model. The IFC data model is a neutral and open specification that is not controlled by a single vendor or group of vendors. It is an object oriented file format to facilitate interoperability in the building industry, and is a commonly used format for BIM.  The format is known as ifcXML. ifcXML2x3 (current version) is currently supported by Autodesk, Graphisoft, Nemestchek and Bentley. http://www.iai-international.org/

FW: Revit Tip- COPING in 3D - peaked brick example

Image
To create the coping that sweeps in 3 dimensions we can use an in place family. (One of the few instances in place is useful)

Create a coping profile – load it into your project.

You can use the same in place family to create the coping for the entire building.

To start: Create an in place family Create a sweep Set the work plane- use "pick work plane" Sketch the path - Use the pick tool for the ridge Add "tails" horizontally so we can join them up later (in image 3) Finish the sketch Select the coping profile for the profile.

Finish the first sweep.

The second sweep will be hosted to the "top" of the wall- reference planes to "host" the base sketch could be used as well…

Once the pieces have been created- Then the multiple planes can be "joined" under the modify tab- this will get rid of the seams- final product shown below:

I am still looking for a 3d sweep/sketch…

Question for those with projects spanning multiple versions of Revit... What strategy has been employed - (1) Upgrade to the latest (assuming all participants are willing/able) or (2) pick a version and stick with it for the duration of the project?

(Knock on wood… )
Revit really hasn't had significant issues with upgrading large projects in the past 3 releases(2009, 2010, 2011). I hope 2012 will be as painless.

For anyone planning to maintain a stake in the industry- Autodesk's subscription option is a no-brainer. And- If everyone is on subscription - then it is a limited issue to keep every project current to the latest release.

Some adopt 'wait till the first patch is released' – which seems be about half way through the release cycle these days; but personally- I would rather test and upgrade ASAP so the new features in the new releases can be leveraged.

Autodesk seems to have done a great deal more R&D as well as substantial beta development for Revit... So where this was an issue with stuff being broken before, they have been pretty good about not releasing junk that is broken or prone to blow up.

In 2009 and converting between previous versions I have seen sheets get mangled, some content in views drop o…

FW: USACE-ISC 3D BIM Visualization | Autodesk Revit for CoS Projects | Bradley BIM

This looks promising...

If this is the case The USACE who currently requires Bentley BIM (a competitor of Autodesk) on Center Of Standardization projects - will include Revit as a platform in their 2012 BIM roadmap.
