Problem: Object turned to wire frame in shaded view, invisible in render view and renderings

Rhino Rhino for Windows

hello,

invisible objet.rar (2.4 MB)

some objects in my file have turned to wire frame in shaded view, and invisible in render view and in renderings. not sure what have happened.

does anyone know how to fix this?
I’ve attached a sample in this post, compressed by winrar.

stsai, try explode and join again and rhino will generate the mesh again.
I don’t know the reason for the issue, but this is workaround.

RefreshShade will fix the render mesh here. Other options are ConvertExtrusion and BooleanUnion which result in a new render mesh being created for the new geometry. However, I’m not sure how the model got in this state of a lost render mesh yet.

Hi Steven- were these objects made in this file or imported/inserted from another file? If imported, can you post that file as well?

thanks,

Thanks everyone for the reply, the rhino support team emailed me back earlier, same as BrianJ said, refreshshade fixed the problem nicely, without having to rebuild anything.

I was working on the file back and forth between Rhino OSX and Rhino 5 SR7 so I suspect the problem might have been from Rhino OSX.

In one version of Rhino OSX, mirror copying an object causes object to go invisble
But after working on the same file in Rhino5 SR7 some objects turned invisible after I closed and open a file.

Thanks everyone for the help

Hi, I’m just tacking onto the back of this thread rather than fully opening a new one.

A user is rotating a rendered view of a small file (12MB 'ish) and is experiencing some slowness when doing it. In my experience, rotating a rendered view in any program is difficult unless you have an amazing computer. This is working off a Lenovo P50 with a NVIDIA M2000M graphics card and 64GB of RAM. When the file is rotated/spun around in wireframe, it’s perfectly fine.

Thanks

Hello - you might try turning off the Skylight in the Lights panel - does that speed things up?

RefreshShade worked for me

It’s worth noting that this problem occurred when I changed the model measurement unit and agreed to change scale the model to fit the new unit.

Is true that RefreshShade fixes the problem temporarily, but it would be nice to get a permanent fix. Is very annoying having to run RefreshShade constantly because the object keep going back to wireframe in the shade view!! It seems like this problem has been around for at least the last 6 years…

Email only the object that has this issue please to tech@mcneel.com. You can use the Export command to save only the selection as it’s own 3dm. This is not an issue that should happen and it may be due to some issue in the model.

In my case I try and , as laborda previous said, but I search for coplanar surface and delete some of them, . A little bit manual, but maybe it helps some people
