Revit Model issues

Kevin.Spear — Wed, 23 Mar 2016 16:58:48 GMT

I have a revit model that looks fine in revit but shows ghosted areas in IW. When i publish the model to the web, those ghosted areas become solid. Any ideas?

In Infraworks:

In web:

link to revit model (shared via onedrive, original was in local working folder):

https://onedrive.live.com/redir?resid=5A070EC9BB50337A!85815&authkey=!AHsrCi0B_CeommE&ithint=file%2crvt

Ideas?

I see what you're saying now that I have brought the model into InfraWorks. I exported it out of Revit as an FBX file and it comes in just fine.

This is bugging me! I've deleted and purged everything out of your Revit model and I'm still getting a ghost image when I import it into Navisworks.

However, if I take that "empty" ghost model model and link & bind it into a new model then import it into Infraworks, it fails because there isn't any geometry.

Just out of curiosity, did you have any mass objects or anything else in there at any point?? I'm just wondering if there was something in the model that looked remotely like what shows up ghosted. Or any objects or DWGs that extended outside of the building like that??

But then there are what looks like columns. That one I'm REALLY confused about.

So... I've tried many things, including all of the suggestions here. Exporting to FBX is obviously a workaround at the moment. We cannot figure out how to get those ghost shapes out of the revit model.

No mass objects. Nothing else comes to mind. No links, no DWG inserted that i can remember. If i ever figure this out, i will post those results. Chalking this up to the exceptions that happen occasionally.

Hi Kevin,

These 'ghost' objects you get in AIW360 are actually Rooms which were once generated in Revit but then deleted. When a Room object is deleted in Revit it still stays in the model but you only don't see it actually. Have a look at your Room schedule, in there it still shows the Rooms which are in your project.

I had a look at your Revit model in Navisworks and there you can clearly see in the Properties that these are Rooms:
