Hi Erich,
The use of = libraries is rather confusing. First, there appears to be quite a few to se= lect from if I want to use what is not in the standard library (introduce m= y own sym/fp pairs).

After all, it is the sym item I select and I should th= en get the associated fp item automatically.

Hi Erich,
I think that I have estab= lished my Linux OS OK and I have executed "sudo apt-get install geda&q= uot;.

I have done:

I get the = one.sch - gschem screen as expected, but when I do Add-Component I get a ve= ry tiny symbol =C2=A0in spite of the symbol shown in Preview being normal s= ize.

I then proceed to click "View-Zoom Extents" and I get= a large symbol which I reduce in size (Shift-z) to make room for other sym= bols. When I add other symbols they are normal size.

Is that the way= to do it?

If I now do:

-rw-r--r-- 1 root root 719 Jul 25 21:54 one.sch-r--r--r-- 1 root root =C2=A013 Jul 25 21:43 one.sch~

Is that (on= e.sch~) OK?

Is there a way to change the size of a single symbol?
That was a lot of questions!

Good work on the fi= le system.

The mai= n thing is to ensure that the=C2=A0 screw terminals you are using are space= d 0.2 inches apart.

You are right, any three p= in symbol can map to a three pin footprint, provided that the pin labels on= the footprint are sane.

I think so. If = I may reformulate it to show that I understand:

In general, gschem is unaware of footprint file names, or the details of = any other attributes you attach to a symbol from a symbol library

The usual procedure, after adding you= r symbol to the schematic from a library, is to add an "attribute"= ; to the symbol, in this case a "footprint" attribute, equal to &= quot;DIP14"

The sch= ematic file will end up with an ectra attribute within the picaxe instance,= along the libes of

&quo= t;footprint=3DDIP18"

The PCB layout editor, when you proceed to lay out uour design, is the so= ftware that has an understanding of footprint attributes, and will search i= ts library paths for a DIP18=C2=A0

Does that=C2=A0help?
