Orcad to eeschema converter?

Adilson Oliveira
 

Hi.

I was looking for a way to expand the Kicad libs adn I found this text
about converting Orcad to eeschema.
This seens to be a little old but it really can convert all Orcad libs
to be used on Kicad? If so, why isn't have been done yet? We would end
up with a huge library.
I don't have access to Orcad but I'll surelly will try to find one if
this is really possible.

EESchema "Page Settings" "Page Size: A4 - Portrait"

Renato Santana Bitencourt
 

Hi, Mr. Charras
?
Please, is it possible to use A4-Portrait Format?
?
Id like to set up the page to Size A4?- Portrait but I dint find it (Page Settiens Window).
?
Then, I set up the Size User?(X: 279.40mm - Y: 406.40mm) and on the screen?worked ok.? But, when I closed e opened the file again the Size User returned X:406.40mm - Y:279,40mm.
?
I tried to change the file .SCH $Descr User 10999 15999 but nothing.
?
?
Thanks!!
?
Your?Kicad project?is very good and the better one.
?

this is probably not the place to discuss it but IME I have only come across spaces in file or path names under Linux when running Windows programmes under Wine.

The group is less than two months old so there is as yet no group policy., However, as a start I recommend we adopt the standard netiquette guidelines in Section 3 of RFC 1855 which can be found here:

Are you running Kicad under Windows or Linux? I know spaces in file names are common in Windows but it is not permmitted under Linux.

Re: Fill zone angle

 

Hello,

I have come across the exact same problem. This is not an issue just
for high frequency behaviour of the circuit but also with the
etching. This staircase step in direction of the 45 degree bend can
create a bridge and with hobbyist means for etching it certainly will.

I have started looking at the code, it seems everything happens in
zones.cpp in the pcbnew subfolder. I didn't have time to dig into it
but I think the main idea is to fill the area with edge joining
tracks going left to right in one pass and top to bottom in another
pass. The thickness of the track is probably given in the fill
parameters but I think this is not the problem.

The problem is with the internal representation of the tracks I think
that do not seem to take the 45 degree bend into account thus
resulting in a gap on the outer side of the bend that gets filled
since it is thought to be outside the clearance area. The inner side
of the bend gets processed correctly since the clearance area of both
tracks overlap there.

If you try with very thin tracks (say 0.025 mm) and a much larger
clearance (say 0.635 mm) it works nicely which leads me to think this
is how the program works.

I will try to have a closer look when time permits, for now this is
food for thought if anybody wants to also have a look.

I think this problem leads to unrealizable boards when using copper
pouring zones which is a pity for an otherwise very good software.

Cheers, Edouard.

Hi,
I tried to create a zone that I filled with copper.
It work good except when there is 45 deg. angles, where the pour
appear
as stair steps.
I was able to modify it in the gerber file by adding a diagonal
line but
for a big pcb it is a big task
to modify a text file and always refere to the coordinate and I did
not
tried the concave curve which I don't know how I can do it in the
file.
Maybe there is an option in Pcbnew to fill the pattern and make
smooth
edge. I ask this
because for high frequency transmission line (PCB coplanar
waveguide)
the calculation of the impedence rely on these gaps between the
signal
trace and the ground plane and I don't know the behaviour of such
stairs
pattern and for the look also.

Is anybody aware about such feature or an easy way to do it?

Thank you

If you look at the ftp site link which is the first one under the Download section on the LHS of the site it will take you to a page with all the kicad files including the sources. The direct link is:

ftp://iut-tice.ujf-grenoble.fr/cao/

Hi again.

They are under the ftp repository IIRC. The links for them are on the
project page, no mistery at all ;)

This is a very good idea to fine-tune the copper pouring, at least the gerber output, this should be very nice.

Re: Availability of program sources

 

OK Juan, cool!

indeed, I missed the topmost links on the full FTP directories and
jumped into the "separate files" expecting them to be there.

This closes the subject.

Thank you all, Edouard.

All the following observations pertain to PCBnew

It seems module names may not contain spaces! If one does, it has
disastrous consequences like the module vanishing into thin air

As a rule I think it is bad practice to have spaces in names.
However,
I agree the documentation should make it clear what characters are
allowed.
Better, Kicad should throw an error if it finds disagreeable
