Convert/upgrade ifc2x3 to ifc4?

Hi,

I wonder if there a way to convert/upgrade an ifc 2x3 to ifc4? The ifc 2x3 was created in revit but I don’t have access to it so I wonder if there is a way to work around it with the upgrade. I wanna open it in archicad but for it to function the way I want I believe it needs to be an ifc4.

You could try with BlenderBIM

Can convert ifc4 to ifc2X3? Thank you!

The Opensource BIMserver has basic conversion functionality as well.

We also provide a cloud based application to convert into 4X3 where you decide the new Spatial Structure and the objects assigned to it, possibly changing their classes
