Hi there,

I have a file that has unreadable geometry. When I open the file, I get the notification below.

Can anyone help me diagnose what the problem is with this file?

Thanks,

Hi @timcastelijn,

Seems pretty self explanatory. Just keep clicking the Yes button until the file opens.

Hi @dale,

I did understand the instruction in the dialog, thank you :wink: . My question was; “Can someone help me diagnose what is wrong with the file?”

I have this issue with many of my files and by clicking “Yes” I don’t know to what extend the file is still valid. I’d like to have more information regarding the file issue (e.g. logs, diagnostics, objecttype, layer or other attributes of the unreadable geometry object, list of objects that did load as expected), so I can solve or prevent this effect in the future.

Thanks,
Tim

Hi @timcastelijn,

Rhino does not provide much in the way of end-user tools for diagnosing file corruption issues.

There are the Audit3dmFile and Rescue3dmFile commands. The latter isn’t really an end-user tool.

In many cases, you’re better off just submitting the corrupt file so one of our developers can investigate.

With your file, I can see Rhino is trying to read the surface parameter mapping tag, or ON_MappingTag, which is part of the mesh data structure. The “chunk” of memory Rhino is trying to read is of the incorrect type, thus the error.

Thanks @dale. (It turned out the issue was related to problems with synchronisation with the cloud storage)
