[kicad-users] Three basic questions from a beginner...

2007-09-20 Thread barkerben
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

2007-09-20 Thread barkerben
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

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.

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. Any thoughts?

  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.
