Analytical line exporting as part of geometry to IFC

luis_brionesalonso — Mon, 15 Feb 2021 12:53:04 GMT

Hi, I have an issue where the analytical line of my Beam is visible as geometry when I load the IFC into Navisworks, resulting in hundreds of incorrect clashes when running a test.

I'm not sure why this is the case because my IFC export settings have analytical beams set to not exported. Opening the IFC in BIMCollab Zoom also doesnt show these lines. I have added some screenshots to illustrate. Anybody know how I can fix it? Using Start and End Level Offset instead z Offset Value would solve it but this would be extremely time consuming for existing projects where this was used.

Hi @luis_brionesalonso

You can disable the analytical model before to export the NWC file

See the next article:

The first screenshot of export settings didn't seem to upload properly. µHere it is IFC export setup 1

Hi Juan,

Thanks for your reply. The analytical model is already set to not export to IFC, the link you provided also does not work for me, I do not get any options to disable the analytical model when selecting the beam.

Analytical models are also turned of in my visual overrides and my IFC export settings are set to 'esport only visible in view'. I think the terminology I used might not have been correct. It could be that what is exported is not the actual analytical line but more of a reference line? I'm not sure how I would call it.

Regardless I need to be able to export the model without that line present in naviswokrs, while still having the analytical model enabled in Revit for analysis purposes.

I still have this problem. Does anybody has a solution? I tried turning off the analytical model and unchecked the box in the properties of the elements but nothing helps.
