IFC Export by Dynamo : User Defined Property Set

#1

Hi,

i want to Export my Revit file as an ifc file by Dynamo. I found this Code and it works. But i Need my own propertySet, but it is not part of the revit Export ifc function. Is there a possibility to solve this?

Hi,

You can try to add below the line “options.FilterViewId = v.Id” the lines :

 	options.AddOption("ExportUserDefinedPsets","true")
	options.AddOption("ExportUserDefinedPsetsFileName","your filepath")

thanks for the fast answer.

    options.WallAndColumnSplitting = wallandcolumnsplitting
	options.ExportBaseQuantities = exportbasequantities
	options.FilterViewId = v.Id
	options.AddOption("ExportUserDefinedPsets","true")
	options.AddOption("ExportUserDefinedPsetsFileName","Y:\da\2017\20170636\revit\IFC\KKI_DefaultUserDefinedParameterSets.txt")

doesn’t work. Or do i have do Input the filepath in an other way?

Solved: I had do Change the “\” to “/” in the filepath. Thanks a lot

You’re welcome.

If you use backslash, you need to double it :
“Y:\\da\\2017\\20170636\\revit\\IFC\\KKI_DefaultUserDefinedParameterSets.txt”

You can mark a post as solution.

Hi,

How can I export an IFC file by “Revit Property Sets” using Dynamo?

Hi,

I will answer your question but please start a new topic.
The original post about User Defined Property Sets was already answered.
Your query is about internal Revit Property Sets.
