:SetValue(Grid,=196,mil) Alternately, use a script to generate your footprint so you can calculate the placements programmatically. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: PCB grid setting

2009-08-24 Thread Vincent Onelli
Hello all, I am working on a pcb that needs 50 pin in the same line spaced .196 inch, I find to be very hard to place one pin at time at equal distance. Is possible to set the grid to 196 mil? Then I can use the grid for place the pin at proper distance from each other I was not able to find, I did

gEDA-user: Trying to plot a serial RLC impedance using ngspice

Hi, The title is quite explicit , I think :-) . Here is the .net file I use : * RLC serial circuit ISRC 1 0 AC 1 C0 1 2 1Om L0 2 3 0.1m R0 3 0 1 Rconv 1 0 100Meg * wcut-low = 1/(R0*C0)=100 rad/s * wcut-high = R0/L0 =10k rad/s .AC DEC 1 1u 1Meg .END plotting V(1), I thought I would
