I have had problems with importing some IFC models into Microstation CE or Bentley Open Buildings Designer lately. The program says that the IFC model is missing some IFC data and terminates. However, my free IFC viewer and WectorWorks Landmark open these IFC models without any issues. Is there a way to fix this behaviour?
Hi Yrjo,
I also experienced this issue since moving to Microstation Update 17 (and PowerPlatform software based on this) and support responded with this:
MicroStation Update 17 is more secure than previous builds and the reason for the file not being opened.
It is possible to set the following undocumented variable IFC_ALLOW_DEPRECATED_SCHEMA=1 that will allow for this file to be opened in Update 17 as with previous versions. (However you might not want too and perhaps instead look at the original publishing source/file).
As mentioned above, the var is not currently documented in the help, and this is currently being reviewed internally.
Regards,

I completely agree, if this is an IFC file from a partner you work with regularly. Or anyone who's open for some feedback.
But in many cases, we are already happy to receive an IFC at all ... Let alone setting any requirements for those IFC's.
