IFC and Unwanted Floating Lines from Structural Framing Model Export

[bails1974]

I have an issue when exporting a structural model to IFC. When it is loaded onto BIM 360 Docs I get a whole series of addition "Floating Lines" as shown on the image attached. The preview image in BIM 360 seems to show there is no model there , with no model preview and when navigating around the model can only be found when doing a lot of searching. However when I load these IFC files into Navisworks or Revit they seem to come in as they should with no additional lines. When other members of the team download them and try to link them into TEKLA the files apparently don't seem to be visible. This probably due to some of these "floating" lines being a long way from the model. I have tried to change all sorts of mapping within the REVIT mapping file option and also various settings within the IFC export tool but with no change in the resulting IFC file. Any thoughts or suggestions on removing these line would be welcome thank you.

Hi @bails1974 

If the model is out of Revit 20miles limit, first move it in original software close to 0, 0  then export to IFC and import such IFC to Revit.

If it is not the case, please post \ send this IFC file.

Hi,

I am also having same issue. Is there any way to control the export of location lines?

This is the requirement. I have a structural framing model which i need to Bind it in another Revit Model

1. I tried linking Revit Model and bind - It didn't work
2. I tried to export to IFC and link the IFC then Bind - It Worked(some items were deleted. Its fine)
   1. Then the location lines started showing up for some of the elements.

Best Regards,

Good day,

Was there a solution for the issue mentioned above by @ashanmugam ? I have a similar challenge with an IFC file I received from an architect where all the structural elements have linked lines quite far away from the model?

Thank you

Anyone can help? I am experiencing the similar issue.

This thread has been in here for 4 years. Won't Autodesk respond to it?

I tried to open the ifc format file in Revit 2020, 2021 and 2022, but the issue is still the same.

Anything curved related will not export as you think. 

Anything with a horizontal span will populate a model line for the base constraint. Be it at the bottom, top , middle + offset values.

i have same problem. is this issue solved?

[patrick.chenN88YE]

With later version(Maybe Revit 2023), that is, with the model upgraded to later version, and then export to ifc again, and it works for me.

Hey there, looking to resolve this same problem, Exporting from Revit 2024 to IFC format.
Have also tried to upgrade the Revit project to 2025 and use the IFC Export settings - however no success so far!

Have checked all the IFC Mapping settings for the Structural Framing Sub Category "Location Lines" and have set this to "Not Exported".
However when the IFC is Linked into Revit the Location Lines remain on, and for some reason appears to be pushed to the Main Structural Framing Category, meaning there is no way to control these lines via Sub Category options within Revit.

Image attached indicates the above.

Firstly - is there a way to remove the Location Lines so that they are NOT Exported to IFC.

Alternatively is there a work around to Remove / Delete / Hide these Location Lines within the Revit Views or Structural Framing Families or can you somehow change the setting of this line to an <Invisible> Line style within the Family itself.

Some advise would be greatly appreciated.
