Model disappearing when zooming in

[m.hoper9DMVY]

Has anyone else experienced an issue with zooming in for certain models? Hopefully you can see the attached video, where I have selected a single model within the facility, but as soon as I zoom in with the mouse the model disappears, and unable to get it back into focus.

If I select other models within this facility, I can zoom and navigate around without any issues

HI @m.hoper9DMVY ,

I'm looking into this more. Can you confirm that all the models you have uploaded are revit? There are two that are cut-off in the video.

Thanks!

HI @m.hoper9DMVY ,

The instances in which I've encountered a model disappearing in the viewer are usually related to the cut-off planes. There is a limitation in the viewer concerning the distance of an object. In other words, if something is drawn too far from the main model, it can alter the cut-off plane and begin to stop displaying 3D information. Navisworks has a similar issue: Link to article 

Whenever I've faced this issue, I've opened the model in question in the authoring tool to check for any odd geometry modeled far from the main model. I would then delete it, re-upload, and this typically resolves the problem. I've encountered this issue more frequently with fab models or dwg fab models.

I'm not sure if this is the issue you're facing, but I would recommend starting there.

Hi Jessica - They are all Revit file

[m.hoper9DMVY]

Thanks Iria - I did have a look at this previously, but I will have a look again to see if I missed anything

[m.hoper9DMVY]

Hi Iria - Thanks for this, I don't believe there are any objects too far away from the main model after checking again. I am still investigating other ideas based on some online forums responses

Done some further investigation into this, and turns out it was the sub-category "Centre Lines" within category MEP Fabrication Pipework which was causing this issues. I have a support call open to initially look at why it doesn't show anything in the 3D view on ACC Docs when this sub-category is turned on

So when filtering out the Centre Lines from the viewer the zoom works as expected? 

[m.hoper9DMVY]

I'm actually having to hide these in Revit before uploading to Docs then Tandem, as it is a subcategory which is causing the error by the looks of it.

But yes once I turn off this subcategory in Revit and upload, the viewing within Tandem works as expected
