Is there any reason why [ System.Data.Spatial.DbSpatialServices](https://msdn.microsoft.com/en-us/library/system.data.spatial.dbspatialservices(v=vs.110).aspx) could not be used directly?

Yes, there is an easy way to do this with xbim. All IFC properties and quantities are published in [several formats](https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD2_TC1/HTML/link/listing-ifc4_add2.htm). And one of these formats is [IFC Property Templates](https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD2_TC1/HTML/annex/annex-a/general-usage/IFC4_ADD2.ifc)!...

Just use reflection. You can also use our pre-computed IFC metadata: ```cs var root = typeof(IfcProduct); var metadata = ExpressMetaData.GetMetadata(root.Assembly.Modules.First()); ```

Thanks, we are glad you like the Toolkit. These methods are used internally my IModel implementations and by IPersistEntity implementations. They are used to store actions so that the transaction...

You can do that.

You can't undo the committed transaction. But you can keep the reference to the transaction and call `RollBack()` when you want to revert all the changes. That closes the transaction...

Hi Adam, yes, we have a plan to implement it in the next few months. What is your use-case for this? We would be very interested if you had any...

Hi all, we have started to work on IFC4x3: https://github.com/xBimTeam/XbimEssentials/tree/feature/Ifc4x3/Xbim.Ifc4x3 This is just an initial code for the schema implementation but allows to do some basic tests and is complete...

Great. Happy to hear any feedback. Here is the overall list of new entities: ```yaml Namespace: Rail IfcAlignment2DCant IfcAlignment2DCantSegLine IfcAlignment2DCantSegTransition IfcAlignment2DCantSegment IfcAlignment2DVerSegTransition IfcAxisLateralInclination IfcDirectrixCurveSweptAreaSolid IfcDirectrixDistanceSweptAreaSolid IfcDistributionBoard IfcDistributionBoardType IfcElectricFlowTreatmentDevice IfcElectricFlowTreatmentDeviceType IfcInclinedReferenceSweptAreaSolid...

Hi @bekraft, thanks for your work! IfcValueHelper is partially generated, so I'll have to change this in the code generator. I run my own comparison on schemas and RC2 changes...
