Though this recent paper might be interesting to our members:

 
I'd be interested in hearing any comments you may have.

I've never had any luck exporting IFC models. I have no confidence in the reliability of the data.

Although a brief might ask for an IFC, most clients (in my experience) lean on Revit/Navis for interrogation, and so we often deliver a Revit model as well; The disclaimer being that if you want an accurate information, stay away from the IFC.

If the Revit export were more robust, the IFC (or Bentley's i-model) platform might have legs.

Hi Elliott.
 
Its my belief that the IFC format is not actually at fault.  I've used IFC products like Solibri which were perfectly accurate.
 
IFC is getting a bad name from the software houses implementation of IFC. 
 
I had a very intresting conversation with Arto of Salford Uni about this, who wrote a paper on IFC and that's what he also thinks, and that IFC will be our future deliverable.
 
Hopefully Autodesk's release of the IFC converted to open source will help.
 
Its a fantasinating subject and key to reaching the "Level 3" requirement mentioned in the goverment report.

I carefully worded my "If the Revit export were more robust" because I thought this might be the case. 

Have software vendors opened up their IFC converter to help drive the industry forward, or are they simply saying; "our product works and if you want it to talk to something else, then do it yourself"...?

Well that is an intresting question.
 
I suspect its an adminitance that it is needs to be open source in order for it to be implemented in a non-commerical way and thus effective way.  In other words, it can be implemented to sit at the same level as everybody else with perhaps requirement to change the Revit software, rather than IFC been made to flex and bend to the Revit way of working and vice versa for Bentley, and all the other software houses.
 
Basically, IFC needs, in my opinion to be given more status as a deliverable.  You couldn't imagine Autodesk or Bentley saying, "You can't produce Adobe PDFs because it doesn't fit our way of working", people would say "well we can't use your product, because we can't communicate our design".
 
You're also right, I suspect that there is a relcuntance, a little like Autodesk previous relcutance to support DGN in opening the up too much at this stage.  I'm sure they would like to see them capture a bigger market share of BIM deployment, i.e. your design partners using Revit, therefore you have to, before making it too easy to deliver truly interoperable information and thus enable software neutral BIM design.

Hello 

I hope you are doing well. I would request you to fill this BIM survey in the below mentioned link

https://docs.google.com/forms/d/e/1FAIpQLSdWvXApHWSNKusQK3Y8Eu52SdJAr_FPZlbWM-i-eBxvQe-hdg/viewform

The main intention of the survey is to identify the interoperbility issues during IFC exchange and the survey wouldnt take more than 10 minutes of your time


Many thanks

Aravindh.R
