DXF2GBR Engine

Example of Command Line and Resource Files

We have the following files in the directory C:\test. This is our "working directory"

ac2000.dxf - dxf file to convert

ac2000.apt - aperture list

conv.bat - batch file

xx.lst - layer list file

The Batch File

The Layer List xx.lst

For each AutoCAD layer that should be converted, the first column is the name of the AutoCAD layer and the second column is the path/filename of the resulting Gerber file. You should quote both the AutoCAD layer name and the path/filename. Use double quotes. The names of the AutoCAD layers were obtained by scanning the AutoCAD and reading the .lyr file.

"0"     "C:\test\0.gbr"
"DIM"   "C:\test\DIM.GBR"
"gaso1" "C:\test\gaso1.gbr"

The Command Line

The command line show below invokes the a2g501.exe engine and references a response file called ac2000.rsp that has been created prior to the execution of the command line.

C:\WCAD\ASM501\a2g501.exe @"C:\test\ac2000.rsp" 0

The Response File

This file contains both the command line arguments and a reference to the aperture file. It is all one line but is shown broken into chunks for clarity.

"C:\test\ac2000.dxf" MM 0.001 "@C:\test\xx.lst" 1.0 -nlnk -t1 -on:21,21 -c:0 "-cfg:C:\test\ac2000.apt"

where:

MM                          units of the DXF file

0.001                       input database resolution

"@C:\test\xx.lst"           the list file containing layers to convert

1.0                         scale factor

-nlnk                       no line linking (required for ASM 5010

-t1                         trace mode =1 (draw plines with width using matching aperture)

-on:21,21                   outline using D21

-c:0                        no compensation

"-cfg:C:\test\ac2000.apt"   reference to the aperture file
