Features
The DLL can be called from Visual Basic or C/C++.

It gives the full translation capabilities of the user interface version
of Arcv2CAD.

It has the advantage that only the DLL file plus a few configuration files
need be distributed with your application.

It uses essentially the same general syntax as Arcv2CAD run in command
line mode. However because it is a DLL you know definitely when the translation
has completed.

output of multiple shapefiles to a single DXF or DWG file.

run invisibly or display Batch Progress dialog to the user.

output of a log file of all operations (useful in development
or for tracking down problems.)

output of all DXF and DWG formats up to Release 2008.
