Tool repair file dwg (autocad)?

[sempre]

Somebody already used some here tool that it repaired file of autocad (dwg)?

[beto]

HY sempre What do u need to "repair" u need to check on first the "header" of file´s , if before u got the files, u did a extraction sector and got some bad sectors, so its not possible to repair it, on that case u need the full sectors from the file
