Importing IFC files

Post by madetea »

Hi! I have recently installed FreeCAD, and I am trying to import some IFC files. I have tried a few different files, but each time I try and import a file I get an error message along the lines of "Exception ([Date & Time]): Expected 8 attributes, got 5 (entity: IFCORGANIZATION)". Do I need anything else (such as IFCOpenshell) installed in order to import IFC files? My system details are:

OS: Windows 7
Platform: 32-bit
Version: 0.13.1828
Python version: 2.6.2
Qt version: 4.5.2
Coin version: 3.1.0
SoQt version: 1.4.1
OCC version: 6.3.0

I am a complete novice at this, so please forgive me if I am doing something daft. Thanks.

No, not that I know.

Checking our IFC reader I found this comment in the source code:

1) For this reader to function, you need an IFC Schema Express file (.exp)
available here:
http://www.steptools.com/support/stdev_ ... x3_tc1.exp
For licensing reasons we are not allowed to ship that file with FreeCAD.
Just place the .exp file together with this script.

2) IFC files can have ordered content (ordered list, no entity number missing)
or be much messier (entity numbers missing, etc). The performance of the reader
will be drastically different.
