As correctly indicated by someone here: the prefix "Pset_" should not be used for user-defined property sets, as indicated in the buildingSMART documentation: standards.buildingsmart.org/IFC/RELEASE/IFC4_1/FINAL/HTML/schema/ifckernel/lexical/ifcpropertyset.htm I did start my PSet created through the schedule with PSet (without "_") to have the filtering option, but probably it would be a better option to add PSet after the name or to use another keyword supported by the Revit export dialog (IFC or Common) to avoid confusion.

in the case we are are converting from Tekla or Archicad to IFC in order to open them in Revit. Revit is not classifying the elements sand categories correctly, they are passed in generic models. how can i solve this ?

@@sbr4897 When loading IFCs in Revit I always recommend to first check whether all elements are correctly classified in an IFC viewer (e.g. if a wall is really IfcWall) - in Revit, you can also double check the import mapping table which can be found under Revit > Open > IFC Options. If it still fails, definitely open a support ticket or report the issue on github.com/Autodesk/revit-ifc

i mean in case we didnt have a well classified IFC coming from ArchiCad or TEkla and we open this IFC in Revit which classify them under Generic Model in this case because the IFC isn t well done.. Is there a Method in which Revit classify automatically the elements instead of putting them in Generic Models?@@BIMmeup

IFC is a topic that is close to my heart. Thank you for insightful explanation as to how Revit supports IFC.

Perfect. Definition I/T in Pset txt file really confused me since testing showed that it's irrelevant. Now it's clear to me. Thanx

Amazing video! Extremely helpful, thanks a lot! Your explanation was just perfect for what I was searching / trying to understand for days.

This was extremely helpful! Thank you so much :) Will look out for future videos.

Hello! Very short and easy to understand video! Is there the possibility to group parameters directly in Revit? For example, a BIM_me_up category of walls? Currently the default grouping of a wall are: Constraints, Structural, Dimensions, Identity Data and phasing.

Hi thanks for this one. I'm just wondering if there is possibility to make workaround, and not use dynamo and other staff in case we want to make concatenation where we combine multiple parameters from revit in one ifc parameter :D (assume they're all the same text parameters, just to ease thingsa bit)

Hi, Thank you so much. Really very useful video. I tried to do export IFC using User Defined Property Sets for different data types like Text, Number, Integer and Boolean. I get the results what I expected but failed to get Boolean value. For boolean data type it shows as string after export. Can you please help me sort this issue?

Hi, I wonder if there is any way to export user-defined PSets under the same IFC Class with different types. For instance: IfcUnitaryEquipment (ROOFTOPUNIT) -> PSetA IfcUnitaryEquipment (SPLITSYSTEM) -> PSetB

A simple question, aber erste danke fur die videos :) I would like to add a new parameter as "Documentary_Stage" into the IFCProject properties (First sheet on IFC tree). The most appropiate, it would be to add this parameter as a File header but I dont know if it is posible so I added the parameter into the Revit Project information (Project information parameters go stright to the IFCProject properties) and I created a UserDefindePset with that parameter and dosent work, but if I add the parameter to an element, it works. Any solution? I can just use IfcTag, but Id like at the other way.

Great vid as usual! When using the "Export only schedules contatining IFC, Pset or Common..."...Is it possible to use a custom keyword instead of one of the three above? I'd like my pset folder name to be "Click here" and not "Pset Click here"...

I actually need to extract concrete properties such as the concrete cover from a concrete element, however I'm really stuck with this. I saw that "Pset_ConcreteElementGeneral" has some of the properties I need, but it is never extracted due to some reason. Can anyone help me with this?

Great video you made, congratulations......, I did some tests here and realized that "Pset_" only works with schedules/quantities, it doesn't work with material takeoff?

Hi, 1) Do you know if its possible to add 'new' parameters to the "standard tabs" in the IFC? Specifically Identification, Location and Classification? 2) Do you know the element list I would need for a user-defined property set that should include any and all installation related objects, but no structural or architectural elements? 3) Do you know if its possible to retract a specific object type from a pset? I.e. IfcElement minus IfcDoor? BR, Maria

Hi, thanks for this amazing video! I just have a specific question regarding the txt file custom property Set. It is explained how you could set the .txt file creating a list of parameters associated with some entities. PropertySet: My Property Set I IfcWall Comments Text Here is my question: what about if I want to associate some particular property, NOT to all IfcWall, but only to a certain type of wall? ( i.e. interior partition, or even a single wall type? ) for example it could make sense to declare the Thermal Resistance capacity for only External Wall and not for interior partitions ... or even it could make sense to include the the degradation status NOT for all Exterior Walls, but only for a certain type of exterior walls ( i.e. the existing one..)

Hi Diego, thanks for your kind comment, always means a lot to hear my content is helpful! Now to your question - you made the question perfectly clear, the only way I could think of how to accomplish this is to leave the values empty - the IFC exporter won’t export a property for elements with no value. Hope this helps?

Thank you for the video. I'm not a regular Revit user but I'm trying to pull data from rvt models into an ifc which I can use in another program. This video has taken me a few huge steps forward! I'm stuck on one thing however. If I edit my DefaultUserDefinedParameterSets file I can extract all kinds of data, but not Force data. For example, something that shows up as 700 kN in Revit comes out as -1 in the ifc file. Is there some trick to mapping forces? This is my file. The "Text" comes over nicely, the "Force" does not.

@@BIMmeup Using IfcElementType works for system families, but it does not work for Loadable Families. Revit 2023.1.

Why, in your opinion, this can t work: "Lunghezza Length Lunghezza Length Lunghezza istanza" Basically for the remapping of a railing we have two family that use two different parameter to define their lenght and in export we would like to export them as "lunghezza" and find it under the dimension tab in solibri. In this case the parameter lunghezza istanza is correctly remapped for as lunghezza for those family who has it. But the native parameter lunghezza of the native railing is not exported anymore.
