Corrupt File not Opening after Saving

[cerdman38]

I keep getting an error message of, "The file you are tying to open or operate is corrupt! The current operation will be aborted. 

My program is updated to the latest version and I have redownloaded the software.

@cerdman38 Thank you for sharing the file. I was able to reproduce the problem but will need a while to look at what is happening here. If you go to the data panel and look at the older versions of your file, which is the last version that you can open? 

[cerdman38]

This is the oldest version every time I try to open it saves as current
version.

So if I open at 6:45 pm it auto saves version at 6:45 pm

@cerdman38 This file is not opening for you right? Do in your data panel if you go to this file and expand on the version is there an older ( not the new) but older version that will open successfully and if so which is the oldest version that will open ?

[cerdman38]

Yes the file is not opening correct.

@cerdman38 Your model contains ten T-spline bodies. One of them cannot be loaded since the body contains invalid topological entities -- Two faces share all of their edges. They are called lamina faces. Fusion can successfully repair lamina faces upon loading most of times, but sometimes the body is topologically too bad to repair. One T-spline body in your model falls into the latter case.

Attached is a F3D file that contains nine valid T-Spline bodies from your F3D file. The model looks blocky with all edges creased. If this is an imported model and you want to re-import the missing body, make sure that lamina faces are removed.

Thank you thank you for you help! this works great.

Having a "lamina face" T-spline isn't supposed to happen, but it managed to make it into that file somehow. We should figure out how it made it in and patch that up to avoid future problems. Perhaps this came from an imported OBJ file or something like that? It would be helpful to know what happened, because this is something we really don't want to happen.
