IfcBuildingStorey ....Name vs LongName

Mats_Knutsson — Tue, 26 Apr 2022 06:53:09 GMT

Hi,

We are testing a new ifc-app and it shows all my stories as one bottom level (no stories). First I thought this was because this app is looking for IfcLongName while I had the name of the storey in IfcName. So I've added the name of the storey to both IfcName and IfcLongName but it still doesn't work. Are there any other places I can look at? When I open the IFC in a text editor I see all positions without a value gets a $.

How does the IFC work in Solibri? Does it display the information correctly, or they way you want it?

It's apparently OK to use Name as a number. From: https://standards.buildingsmart.org/IFC/RELEASE/IFC4/FINAL/HTML/schema/ifcproductextension/lexical/ifcspace.htm

The following guidelines should apply for using the Name, Description, LongName and ObjectType attributes.

Name holds the unique name (or space number) from the plan.
Description holds any additional information field the user may have specified, there are no further recommendations.
LongName holds the full name of the space, it is often used in addition to the Name, if a number is assigned to the room, then the descriptive name is exchanged as LongName.
