Output Composite (Dark/Clear) gerber files using EasyGerb.



documentNote: This Learn Guide assumes that you have already loaded EasyGerb into your AutoCAD version. If you haven't successfully loaded EasyGerb yet, goto Loading EasyGerb into AutoCAD.



Command Sequence


1. Open sample AutoCAD drawing file "compos.dxf".  This file is located in the folder:  ...\EasyGerb\Examples.


2. At the command prompt type: "easygerb".  The main EasyGerb dialog will now appear.


3. Verify the Output Folder.  The location where you want EasyGerb to output Gerber files.


documentWindows Vista Users: You will need to choose an Output Folder that you have write permission to.  If not, EasyGerb will complain that it cannot write files to the output folder.  We recommend outputting to a temporary in your folder "...\Documents\easygerb"


4. Go to "Output Settings:", and select "RF-Flex PCB/Chem Milling".  This feature quickly optimizes your layer settings (such as FCB, OWP, FRD,FRS)  for the most common type of drawing you're translating - in this case a "Chem Milling Mask".


documentNote: To review the Layer Table Options (such as FCB, OWP, FRD,FRS) , see EasyGerb Dialog: Main


5. Click button "Merge Layers..." to create the merged composite layer.




6. Click button "1" to create the compsote layer merge.  The composite merge dialog will appear.


7. Enter  Merged File: "composite.gbr"


8. Assign Layers to Merge: (see below for example)

GROUND     ---------> Dark

VOID ---------------> Clear

Inner ---------------> Dark




documentNote: When creating compsite layers, the layer "sequence" and "polarity" order are very important.  Changing the layer sequence or polarity will drastically change the results of the final composite image.


9. Press button "OK" to return to the Merge Dialog.


10. Press button "OK" to return to the Main Dialog.


11. Press button "OK" to select objects.


12. Select Objects and "Right Click" to begin the translation.


That's It, EasyGerb is Finished!


13. Review the EasyGerb Finish dialog.
