Hello,

We are processing E57 scans on a command line script. Sometimes it happens that there is failure in file transfer and E57 is corrupt.

Currently, command line processing will keep on processing those scans CC was able to read before error in the file, like this;

... and will eventually save data.

I think it would be good to be able to halt the processing completely if an error like this occurs.

Hum, that would be a big change of behavior. Not sure what other users would think about that?

I understand, it's not a good idea to change command line basic behavior and break scripts people already use.

I'll take a look at alternative methods how these broken files could be recognized before processing in CC.
