Hello

Welcome to the Autodesk/AutoCAD Forums !

Q1) Please can you share with us ONE of your "permanently" corrupted drawings ?

Q2 Are you using a "special" version of ACAD like : Cicil, Architecture, MEP, etc ?

Q3) Are you using an other specific application on top of your ACAD ?

If YES, which one ?

Thanx for reply.

I cant share file here. can you share your mail id for this?

I am using AutoCAD 2015 (not special version) and not using other specific application.

Hello

Ok I sent you a private msg ...

[designtech43]

i hope you checked that corrupted .dwg file.

one thing i have to say..

After repairing and editing again corrupted file is giving that error in some machines but not in every machine. in some machine that 2 methods are working but in some machines not.

The problem is with my machine? Reinstall AutoCAD/Format machine will solve this problem?

Hello

YES your file has a strange corruption coming from Bad Geometry inside Blocks !

Many many errors like >>>

AcDbBlockReference(13055F)  scale invalid               uniform
Step 1 40300   objects controlled AcDbBlockReference (130694)  scale invalid               uniform

<<<

You can correct with RECOVER and ReSave the drawing but the errors are always here ...

I have used some special routines to purge your DWG but the result was not perfect !

So I save the drawing as R12 DXF and reloading it : no error !

... But a few things have been lost ...

Tests have been done with ACAD MAP 2012 and with ACAD 2014 ...
