Mapping IFC Paramaters and Export

[Anonymous]

Hello Revit Community,

i am working on IFC Export. I want to create Models and Export them into clean IFC files for CAFM usage etc.

But i still have Problems with the export. Here a generice furniture Family called "Möbel_Allgemein_pi".

 

The Parameters grouped under IFC Parameters are SharedParameters and Instance.

I want to Export These Parameters to IFC.

So the ifc structure is:

IfcFurniture 

      Pset_FurnitureTypeCommon

              NominalHeight

              Nominal Length

              Nominal Depth

I use the IFC Export Add-In.

     IFC Version IFC4 Design Transfer View

     Property Sets: Export Revit Property Set, Export IFC common property sets

The Export only brings following data:

 

i know the most of the data are revit properties, but even there my shared Parameters are not listed.

What am i doing wrong?

Thank you in advance!

Kind regards

Raymond

Can you try the following?

You have now placed your parameters NominalHeight, Nominal Length and Nominal Depth grouped under "IFC Parameters".

Edit the family and group those three parameters under a different group (e.g Other).

Load the family into a project and export to IFC and see what happens.

Beste Louis,

thanks for your idea. Yesterday later the day i found the solution.

It worked with this way: http://revitiq.com/creating-custom-ifc-property-sets/

You just have to be aware of very correct pronouncing 😄 and Play around with the <element list seperated by ','>-Element. For some parameteres i had to choose IfcElement instead of IfcElementType.

Unfortunatly it is not possible to just use the enitiy-parameter-relation ifc structure in revit. i dont get why there is no Parameter Group in revit referncing the ifc Parameters.

Kind regards

Raymond
