Many of us use Tekla BIMsight or Solibri for IFC viewing, but there is another free option: FZK Viewer. It is just a 10mb download, unzip and go.

It has a Walk tool like Navisworks for easy navigation, and it can even export to a number of formats, including:
DXF (cool! quick IFC to DXF conversion anyone?)
VRML 2
STEP
Collada
Google Earth
CityGML

Additionally, it can open gbXML and GML files. All in all, a handy piece of software to have if you are dealing with IFCs on a daily basis.

Oh, did I mention it can Merge .xyz point cloud files to the scene?

On opening an IFC, it produces a log file that can quickly locate geometry problems:

Something popped up on Exchange recently, got tweeted, and then disappeared… but now its back!

This addin allows simple import of PDFs directly into the Navisworks 2015 Project Browser as sheets that can be reviewed, marked up and quantified. Previously, to accomplish this you could open the PDF in Design Review with vector information, save as DWF and “Import Sheets and Models” to bring the DWF sheet into Navis. As you may know, the 2015 release introduced a lot more Quantification functionality for 2D, and I believe this new PDF importing tool will become a key part of that workflow.

In short, it seems that the sheet import process for Navisworks 2D documets is about to get a lot easier!

I hinted at the document aggregation possibilities in Navisworks back in this post.

I enjoyed reading a recent, brutally honest and candid post by Luke Johnston (not me 🙂 over at Britex. Here are a few pertinent points:
“You only have to scan the room at the various ‘BIM groups’ that exist both online and in person to see that manufacturers are by all definitions underrepresented.

Having been on my own ‘BIM journey’ for the past four years, I think manufacturers are scared. They’re scared by their own ignorance. They’re scared of investing great amounts of time and money into a process or software format today that may be superseded by something else tomorrow. They’re scared of investing in the creation of BIM content only to be told by their clients that they won’t use it for one reason or another.

There have been plenty of times I have been deliberately made to feel out of place by ‘BIM Geeks’, times where I have had to ask stupid questions in a room full of my peers


More than anything right now, I think manufacturers need encouragement and education. Lots of education…

let me convey a personal thank you to all those ‘BIM people’, from all around the world, who have taken then time over the past few years to educate me in all things BIM…”

If anything, I think that some of the points above should give us pause as BIM professionals – are we being inclusive and helpful to manufacturers and non-BIM people? Or are we perhaps trying to preserve an exclusive “BIM club”?

A great way to test if you know What Revit Wants is to try and run a complicated high rise or health facility using model groups. The principle and general functionality of groups is fine, but they can get very difficult to manage if not treated properly. However, they can be mastered.

As Ceilidh Higgins puts it:
Whilst groups are error prone and seem to have a lot of bugs … they are still the best available solution within revit for collecting together repetitive sets of objects. 

She recently presented at RTC on this subject, and she has provided the associated presentation slides for download and viewing.
