Hello, I am an Expert in CAD and GIS, I convert formats, I adjust them, I interpret them and I also recover them when the content is lost
Send me your DWG and BAK file from the last time you saved it, and we see if it can be recovered or not, write to me and we will arrange for you to send it to me by mail, I may have it from one day to the next in the best of cases in hours.
I also need you to tell me the history of the file if you process it or someone else processes it and what happened when the messages that went out were damaged, if you have the screenshots of the messages it would be very helpful, and tell me exactly what the project is about as to give me an idea.
Your file will be treated with complete confidentiality
Greetings from Peru
