Help!

My file is not opening after updating just now, It previews fine in Windows Explorer… Another recent file opens fine.

I really need it back and I cannot open it in version 8!

Thanks

Hi Sach -

From your image, it appears to be stuck in the meshing phase of opening the file.  
Have you tried starting a new file, setting all viewports to `Wireframe` and then importing this file?

If you could provide the 3dm file, I could test some more here. Sensitive files can be uploaded from [https://www.rhino3d.com/upload/](https://www.rhino3d.com/upload/)

Thanks for your quick reply @wim

Yes, the file imports ok after setting VPs to WF mode, then it shades okay.

@wim  
It’s very odd – I Saved As as a new file name and it opens fine.

Hi Sach -

> It’s very odd –

Perhaps one of the viewports in the original file is in a technical display mode?  
If you post the file, we can double-check to make sure there isn’t a regression in the newer builds of the WIP.

Thanks Wim, As far as I’m aware, Technical mode was not activated.

Were there clipping planes in the model? We recent made a change to use a new low level intersector that our geometry team has been writing and this would affect things like computing the section information when clipping planes exist.

Hi @stevebaer

I have 2 planes, one is active, in the original V9 file.

In the re-imported V9 file, the planes are inactive upon opening the file. Enabling one of them crashes Rhino and leaves some extra files in the folder – see attached. The second plane eventually activates after a few (long) seconds!

Does this help in any way?

I had to import the file into a new session and save back to Rhino 8 so I can continue working and using the clipping planes. Doing this has lost all of the customisation to the dimensions, saved viewports etc.

Do you think I can get up and running today back in version 9? Otherwise, can I re-install the previous update so I can continue uninterupted?

Thanks
