Re: [kicad-users] Re: Mils

2007-10-15 Thread Robert
 I've never seen or heard of one that used 'thou'.

For the benefit of those unfamiliar with the term, 'thou' is defined as:

an alternate name for what Americans call a mil: a unit of distance
equal to 0.001 inch (25.4 micrometers). This name originated in Britain,
but it is now common in the U.S. also. -
http://www.unc.edu/~rowlett/units/dictT.html (University of North Carolina)

So although I accept (from our discussion here) that 'mil' appears to be
more widely used than 'thou', my (British) engineering background means
that 'mil' is 'millimetres' first, 'milli-inch' second.   It's like the
word 'pants', which to me is underware first (UK meaning), and an outer
garment for the lower part of the body second (US meaning).   I could
avoid this issue altogether by using my preferred measurement system,
which is metric.   However when I switch kicad to metric I get
unfriendly grid choices, such as 0.127mm.   Since it looks like 'mil' is
more widely used to mean thousandths of an inch, is there a way of
getting kicad to give me rational metric grid options, so I can work
purely in metric without immediately hitting a brick wall?

BTW, this US vs UK vs the world business leaves a bad taste in the
mouth.   This isn't a battle, it's a matter of the same word having
different meanings in different parts of the world.

Robert.

Re: [kicad-users] Undo ruler

 Hello, I am a new user of Kicad. Is there a undo function in PCBNEW
 and 
 a ruler displayed with the dimension of the drawing with units
 choosen?
 
 Another small thing, how do I turn on snap-to-grid feature in PCBNEW?
 
 TIA
 
Yep the ruler is called Add Coatation and it is on the right menu. Do
not use it on copper layers . The display metric or imperial depends on
the mm or inch tools on the left menu.

There isn`t any Undo feature implemented yet i think , but there is
Undelete function .

Snap to grid and snap to electrical grid is default turned on.
I think that it cannot be turned off exept for magnetic pads which is
from the Preferences -- General options menu.

Cheers



[kicad-users] Which way around is the CP cap symbol?

2007-10-15 Thread jeremy
In Schematic, the Capacitor (Polarised) - known as CP is a symbol that I am 
not familiar with.

It's a dark box inside a sort of shield. Is the dark box +ve?

Thanks.

Heh.   It was unfamiliar to me too, so I just created a new capacitor
using one of the symbols I recognise.

Regards,

Robert.
