ORD IFC Export

Hi All

We have recently tested the IFC Export functionality in ORD 2018 Release 3. We have an expert in IFC who has spotted the following error, highlighted below:

"

Just to note a couple of aspects of the sample openroads IFC file that isn't compliant with the schema.

First, the project line has a reference to ($) which isn't valid.

#2=IFCPROJECT('1ltWbrLqb6OgXtpp_gmwDL',#3,'C1485-Corridor-N7-NB-Bridge','',$,'',$,($),#9);

The item that should be referenced is in the file, and I manually changed this line to:

#2=IFCPROJECT('1ltWbrLqb6OgXtpp_gmwDL',#3,'C1485-Corridor-N7-NB-Bridge','',$,'',$,(#22),#9);

It's nice that openRoads is already using new features of IFC4.  The mapconversion line also needs an adjustment.

#30=IFCMAPCONVERSION($,#31,0.0,0.0,0.0,$,$,$);

The first attribute SourceCRS is not optional.  This should also reference the IfcGeometricRepresentationContext

#30=IFCMAPCONVERSION(#22,#31,0.0,0.0,0.0,$,$,$);

"

This is causing incompatibilities with other packages. Is there an expert on IFC who we could discuss these kinds of issues with?
