Hello,

I used FME Workbench 2017 to generate an IfcSpaces from shape file with footprint polygon and height information. I managed to create space geometry but I could not create longitude and latitude for IfcSite. These values were empty ($). Is there a way to fill theses values with FME Workbench 2009 ? Knowing that today I use a not very powerful method which consist in replacing the text of the end line of IfcSite definition : .ELEMENT.,$,$,$,$,$) by another one with right values : .ELEMENT.,(42,45,2,206849),(0,-25,-12,-380875),0.,$,$)

Or perhaps is there a way to write ifc_object_placement for IfcSite which could be another solution to have correct placement ??

Thank you in advance for your help

Best regards

Bruno

Hi @brunohilaire,

Please try setting the RefLatitude, RefLongitude and RefAltitude attributes on the site feature in FME 2019.1 or higher.

You can get the latest version of FME 2019 from www.safe.com/download.
