Subject: [kicad-users] PCB visibility and layer questions

?

1) When I place modules on a PCB layout, the text shows both the part value (like "1.0K" or "CD4046B" for example) and the reference designator (like "R5" or "U12" for example). Additionally, the modules typically might have an outline on the silkscreen layer. I have KiCad set up so that the top silkscreen layer is dark cyan colored (default I think). However the part value and reference designators are in a light gray. What layer are they on? If I put text on the top silk layer ("I/O Port" for example) and double click on it, the Text Properties dialog has a drop down that shows it is on the top silk layer. I could change the layer with the drop down if I wanted. If I double click on the part value or reference designator text, the Footprint Text Properties dialog has no such option for setting the layer. What layer are the part value and reference designator texts on? When I print each layer out, these texts are replicated on the top silkscreen layer only, but if I go the the layer visibility tool bar on the right and uncheck the top silkscreen layer, only the dark cyan things go invisible, not the part value or reference designator texts.

2) A related issue, how would I set it so that the part value and reference designator texts show up on a mechanical or assembly techical layer while at the same time having only the reference designators on the top silkscreen layer? It seems really hokey to have to manually double click on every part's part value text and make set the text visibility to invisible.

3) If I go to the layer visibility tool bar on the right and uncheck all the layers, I would expect each layer to become invisible one by one. Eventually nothing should be visible. But all the parts remain. If they are SMT parts, they are colored like the top copper layer (sorry, Front), but all the top copper traces go invisible while the top side SMT parts remain. What layer are the parts on?

Thanks!

I believe it is because your spoke width is smaller than your minimum width, although the text in the error seems to say the opposite of what it should say.?? The Minimum actually has to be set smaller than the Spoke width to work, setting them the same will still give the error.

Subject: [kicad-users] Copper zone problem


??
I have just done a 4 layer PCB layout with KiCad and am trying to make the inner plane layers. I click on the Add Filled Zones button on the right tool bar and the cursor changes to the pen shape. Then I go to draw the zone outline and click. The Zone Properties dialog pops up. I select the net that I want connected to the copper plane (GND for example) and click OK. An Error box pops up that says "Thermal relief spoke width is large than the minimum width". This is unexpected because the previous Zone properties dialog says that the Miniumum Width is 0.0080" and the Spoke Width is 0.0060". I did a Google search on this error and it turned up a forum discussion from several years ago on this issue but it is unfortunately for me posted in German. Does anyone have a clue as to what this error message is trying to tell me?

Thanks!

Hi,
I want to make a pcb with a double aop,so i try to use in the library
the linear componant "tl072", in the schématic it's ok, after
anotation the référence of the first tl072 is "U1A " and the
second is "U1B".
But after generate the netlist and open CVPCB there is just one tl072
call "U1", and when i open it in PCBnew, the module of tl072 (dip 8-300)
is missing ??!
someone has a solution for this problem, is it a bug or may be i forget
to do something ? thank's

Christophe.

KiCad has two ways to move components. First you already know; you are

pressing M and the component will move without their connections. The
second one is the Drag (G key) command. If you press G and starting to move
the componnent, the corresponding tracks will stay connected and their last
segments will be moved too. During draging you may also use the Rotate
command (R key) and tracks still be connected.
If you only need to rotate the component with keeping tracks just press G
and without moving the cursor press R as many times as you need.

Thats a great tip Kerusey!!! Thanks :)

I was about to leave KiCad for this annoying thing!!! Not anymore. But I
seriousy think i would end up with a question mark for simple things. So,
could you point out any of the best resources available ?


Thanks and Regards,

Dear All,

I just started using KiCad. But there is one annoying feature. After i connect wires to components, if I rotate or move the components, wires break away from them. That really annoying. Is it so or am I doing it the wrong way?



Thanks and Regards,

Hello all,
is there description of modules library file format?
I found one for schmatics here

But for PCB/module the description is poor.

Thank you,
Pavel
