class ifcpatch.recipes.SetRefElevation.Patcher(src, file, logger, elevation=0)#

Sets the reference elevation of all IfcSites

To completely reference model coordinates, a reference elevation should be specified on the IfcSite. This is often omitted or not possible by proprietary BIM applications. This patch lets you set the reference elevation attribute explicitly.

Note that this does not physically shift the Z coordinates of anything. The reference elevation is simply a numerical attribute.


elevation (float) – The elevation to set.


# All IfcSites will have their reference elevation set to 42.
ifcpatch.execute({"input": "input.ifc", "file": model, "recipe": "SetRefElevation", "arguments": [42]})
