Exporting IFC quantities

Post by Sebaztian »

Hello everyoneç

Sorry if this question have been aswered before, i have a model that i exported to IFC, this model have steel profiles and concrete elements. The question is how could i get the some properties of freecad exported to IFC, at this moment this properties are not exported.

In the ifc file there is a line that refere to a quantities, but no quantities are exported.

#16455=IFCPROPERTYSET('0yo9mpk9j7iBt1iBqJ$OK0',#5,'Qto_Beam_BaseQuantities',$,(#16452));

in my experience the ifc export in freecad works best with simple copies. if i want to get information from freecad into the ifc file, i rename the parts with the desired information. if the recipient wants them as attributes, i add them with usbimviewer

So the only way that i could transfer information is editing the IFC file after is exported?

no, that's just the most stable and secure method (in my opinion)

the BlenderBIM Add-on in Blender is a full ifc editor..
some ifc to json or csv is also possible.. even scheduling..

there is some work on having a 'live-link' between FreeCAD and BlenderBIM (may be via sverchok) but i do not know the state of it.
