Missing length data_ifc

When I read an ifc file, the railings don’t get a length parameter.
Thank you again

Hi, this happens because railings (as well as curtain walls or stairs) can’t be kept as parametric objects after being exported to IFC. And the same happens when you import IFC files that contain railing objects generated in other software. The “length” property is calculated on the railing object by VisualARQ when it is still a true VisualARQ railing object. When this object is generated in other software, and you import it as IFC, it is recognized as a block with the ifcRailing category assigned.

Thank you a lot!
