Hi Dmitry- I would consider the file lost, I’m afraid, if Rescue3dmFile does not find enough to be useful. I would check for a .3dmbak file of the same name in the same folder and see if that will at least help in recovering the info. I assume you used the Recover option on Rescue3dmFile, and ReadAll? Can you tell what entity it chokes on? If so, you might be able to use the Skip option. No doubt you’ve been through this but see Help for details on the command to help you try to recover at least parts of the model.
