ACAD file format

I have a drawing emailed to me that has the email text somehow
concatenated to the start of the drawing file. I can see where the text is
and remove it, but I cannot see where the start of the actual drawing file
is.

Anyone know what I should look for in the code that indicates the start of
the file?

TIA.

 

The first few characters of an AutoCAD file are generally
AC1014
AC1015
AC1016
or
AC1018
depending on the version with which it was created.

Thanks for that, Paul. I'll look for those in the code.

 

Good luck. If you're fortunate, you may be able to recover the .dwg file.
But it wouldn't surprise me greatly if other corruption crept into the file
as a result of the concatenation and whatever other processes that email
went through. It may be safer to just request another copy from the source.

Already done - but replacement not yet received. It's a company known for
tardy response times! (8-((

<Later>

Had a look at the file and found AC1015. Deleted everything before that
and then discovered it was produced in an incompatible version.

Used Convert to convert it to R14 and there it was. I guess it was drawn
in R2000.

Thanks for your help.

Brian.

 

AC 1015 *is* A2k, or R15. Remember how they started avoiding odd numbered
releases?

 

That confirms it...

....and it contains exploded and disassociated dimensions! Means that I
can't stretch things without redimensioning. Pain.

 

Why? Are they making StarTrek films? <g>

Ya lost me....

 

Many Trekkies (or is it "Trekkers" these days?) feel that the Trek films
followed a similar odd/even quality cycle.

FWIW, Corel Draw is the same, but inverted...
odds-good, evens-baaaad.
