[kicad-users] Three basic questions from a beginner...
Hello, Can anyone answer the following basic questions from a beginner (previously used Eagle): When going from schematic to PCB I need to choose the package for each component. The filtering option appears to have o effect - I always see all 356 packages for each component. Is there a reason for this? Also, since the package is not tied directly to the device as in Eagle, how do I map device pins to package pins? Is it just done in numerical order? Final question... keeping the PCB and the schematic in sync...if I route a board, but then go back and alter the schematic, do I have to start my routing etc from scratch or is there a way to just update what has changed? Cheers, Ben
[kicad-users] composite layers and negative plots
One more question (I have answered the above myself via experimentation). I got the following from Olimex, who I use to etch boards: Hi, Your gerbers contain composite layers and negative plots (G36 G37 commands). On such gerbers we can't do DRC check, panelization nor to ensure correct phototools plotting. Please ask your cad vendor how to generate your copper pour with stroke hatch filling instead composites and send your files again. Thanks Can anyone answer his question? Cheers, Ben
Re: [kicad-users] composite layers and negative plots
I do not understand the question. My kicad generated gerbers do not contain G36 nor G37 codes in copper layers. Neither for the tracks nor for the zones. Pedro. Your gerbers contain composite layers and negative plots (G36 G37 commands).

I think the problem occurs when I pour copper areas: find out how to generate your copper pour with stroke hatch filling instead composites and send your files again When I do not pour, there are not G36 or G37 codes, when I do they appear.

Cheers, Ben If you go to the library editor, you can specify a package for the part. Then when you place it in your schematic, the package will be tied to the part. If you change the schematic, save the netlist and re-run cvprt to update the part and package references. Then in the PCB program, read in the netlist again. That will update all of the connections. You will not have to start over routing. Any new parts you added will also have the packages added to the PCB. The only thing to watch is if you delete a part in the schematic, you will have to manually delete the part on the PCB. Dave - WB6DHW http://wb6dhw.com
