Revit 2023 IFC Exporter Fails #590

Open bechtel-inge opened 1 year ago

bechtel-inge commented 1 year ago

My firm recently upgraded from Revit 2020 to Revit 2023. The built-in exporter in Revit 2023 fails to export IFC files. We've also installed the Git-hub IFC Exporter (1.0.0, 1.1.0 and 2.3.0) but none of them work in our environment. The error we get is the well-known "There has been an unrecoverable error during export. This may be because the file is too large to export....". The models we are using are very small (no more than five walls). We are also testing with production models (we don't consider them "large" at all). We are using a multi-user Revit license since we run Revit off the internal network. We have updated the Revit Client to 2023.1.10.4, but still no luck. Any pointers/help you might provide to solve this problem will be extremely appreciated.

.. forgot to mention: IFC exports from Revit 2020 work correctly. Revit 2023 exports do not.

Do you also have Enscape installed? There was a known issue where slightly older versions of Enscape blocked Revit's ability to export. Upgrading Enscape solved the issue. Do you get the same error if you export a blank model or a model with one wall? Because yes, that isn't too large.

Angel, First of all, thanks for your quick reply! .. In my search for a solution via this site, and others, I became aware of Enscape being the culprit. However, I have used the Add-in Manager tool (Autodesk) to identity all the add-ins that are installed on my machine and Enscape does not show in the list. I have manually disabled all of the add-ins on the list, both Autodesk-developed and the ones I have created for Bechtel. The only add-in I have left active is the Navisworks exporter add-in (Autodesk). I will be disabling it this coming Monday when I get back to the office.

One more source I found that talks about the problem is a github user that debugged the IFC exporter source code. Aparently there was a problem with permissions on an Isolated Storage resource. I don't know if this is affecting us too (I am unfamiliar with the Isolated Storage namespace; the only thing I gathered about it is that Isolated Storage is a fancy mechanism to store application-owned files in a protected manner.

One more thing: we do have a test environment machine that has Revit 2023 installed. I verified that only Autodesk add-ins are active. IFC exports fail on this machine as well.

Thanks again Angel for taking a look at my post. If you have any more suggestions to share, please do so.

So back to the second part of the question - is this for any export or for this file? If you send the file to us we can identify the issue. You can send to my work address (angel.velez@autodesk.com) and it will be treated confidentially.

Hello Angel, I am having the same issue: unable to export from rvt2023 the IFC I'm able to export from rvt2021. I just wanted to know if you found the source of the problem. Thanks in advance
