Hi,
Does anyone have any source code that allows batch conversion of AutoCAD dwg files to dxf?

Thank you

There is a free stand-alone utility available from:

Most of the native Delphi untis I have seen for this are commercial, closed-source software, and they are *very* expensive!

Hi there, thank you for your reply,
I am aware of that utility - but I need to develop a custom application - either in VB or Delphi that automates the batch process by calling the AutoCAD API.

Thanks for your time

You could try to find the correct interface to solve your problem, if that's possible. Perhaps AutoCAD has an interface server to perform that conversion. You can let Delphi create the necessary unit by either using "Project|Import Type Library" or "Component|Import ActiveX Control" command.
If it is not an interface, then a websearch for technical info on AutoCAD or some developer's book might give you the correct exported routines.

It has been a few years since I used AutoCAD,
but if I remember correctly, it has an extensive
and well-documented COM interface. You can create
an instance directly from Delphi using something like:

MyCad:=CreateOleObject('AutoCAD.Application');
MyCad.ActiveDocument.Load('somefile.dwg');
MyCad.ActiveDocument.Export('somefile.dxf');

- This should be regarded as "psuedo-code" ,see the AutoCAD
documentation for the exact syntax.

Hi Emma,
Have a look at this shareware tool for conversion into DXF: http://www.cadsofttools.com/en/products/cadviewx.html - it is an ActiveX technology though.
You can look here as well: http://www.cadsofttools.com/en/documents/what_to_choose.html
Good luck!

You assign the method you want to fire to the event handler that you want to trigger it. example.

Before you start using style-codes, please note that you have to close ALL tags.Please use
the preview function to make sure that your message is shown as you want it to be.

That's really a good try.
