I’m using the Educational Version of Rhino 7. I save that file in my external drive - SSD.
I used “Rescue3dmfile” command and analyzed it, it says
"To find damaged parts of the file, search for the word “ERROR” in the following list.
====== FILENAME: D:\Thesis\모델링\Physical Model_2.3dm
ERROR Read3dmStartSection() failed"
Please help me out as soon as possible this is for my spring graduation exhibition project.
Thank you for your help guys
I looked into this file with tex editor and I found that there is no a kind of section saying this is a 3d geometry file - like below. The below one is from another file that runs well without any error.
My file was definitely Rhino file and I don’t know why it was changed into not Rhino ones…?

Your best option is to go to your Windows Recycle Bin, find the most recent version of the file, restore it, then rename it back into your Documents folder.
You may have to remodel the most recent changes.
I’m afraid there is no hope for the damaged file.

Hi Hari -
I’m afraid that Audit3dmFile gives me the following:
Testing 3dm Archive: C:[…]\Hari Killada - 24ft chajja.3dm
ERROR - Unable to read start section.
If this was a 3dm file, it is has been corrupted and can no longer be read.
Running Rescue3dmFile and picking the List option shows that there are no recoverable objects in that file.
As John wrote, your best option is to check the Windows Recycle Bin and find the last autosave version of that file.
