Fill Zones Create Clerance

Hello, I am heaving difficulty with Fill zones:

  1. Super New to KiCad.
  2. The board is very simple.
  3. There is no Schematic.
  4. I have selected an outline of my board(GND section) and created a fill zone. When filling a zone it seems like KiCad is trying to keep a clearance of outline as it thinks these are traces even though they are not. They are border of fill zone GND outline of the PC board.
  5. In Property of the Fill zone I set “Clearance” as 0.

Please advsie on how I can remove this spacing,

Thank you

There is your problem.

Beginners often think that creating a PCB without a schematic is easier, but it is not.
I understand some beginners think this may be so, but that is mostly ignorance.
Simply said, without a schematic, KiCad does not know what to do and it makes a mess of things.

If your PCB is so easy, then also draw the schematic.It’s just as easy.

Also, I have no idea what you are trying to draw in your screenshot.
KiCad tries to be a program fit for real work, and an important part of that is gerber file creation, and a proper PCB outline is a part of that. To make a proper PCB outline, you have to draw lines (and/or arc segments) on the Edge.Cuts layer.

Another important thing you are probably ignorant of, is that zones should never be to the edge of the PCB, because of burrs caused by the routing can be a source of short circuits.


Disclaimer:
I do not mean “ignorant” in a degrading manner, but just as a “lack of knowledge” as it’s defined in the dictionary.

Useless response TBH.

As I outlined I have no schematic. I just need to know if zone can be filled or NOT.

You went over Half paragraph with useless information that doesn’t contribute to solution.

In addition you don’t need to see my board. My question is about fill clearance not Design.

In the future if you don’t have an answer please don’t respond to topics it saves everyone time.

Well then.
(Mod Edit by hermit) Please do draw a schematic.

Edit:
In order to prevent further escalation it is unlikely I will add another post to this thread.

That was my last option from the beginning.

You only said you don’t have a schematic. Paul’s response was fair and good. You can add nets without a schematic in the PCB Editor (Inspect → Net Inspector) and then add the net to the zone, but it’s about as easy and quick to draw a schematic, if you are willing to learn KiCad and PCB design.

It’s also true that you MUST have a real board outline for KiCad to understand it correctly and the board manufacturer to accept and understand it, and even if you are not going to send the design to a manufacturer, you still must use KiCad as it is meant to be used. You just don’t have any real reason to use copper lines as board outlines, so I don’t think anybody is willing to take a look at your problem. (I assume the red lines are graphics in the copper layer, although I can’t be sure – and that’s why attaching the example project is a good thing, it’s always unambiguous and includes all needed information about the problems and for the possible solutions.)

He truly answered your question correctly.

Hello, I do have Edge Cuts layer that defines outline of the board it self. The copper Layer ground is also falls into this dimension GND besides lines. Maybe I wasn’t clear here. As per previous board is simple there are two lines surrounded by ground. Lines don’t connect to anything as they serve other purpose. Area surrounding them needs to be filled with ground, I have attached picture for reference. Doing schematic for this where lines, neither ground are connected along with 0 pads… I don’t think KiCad will understand this. As this just a simple board to form connection with something else by using the PCB lines. For example if I go to schematic and draw few lines and the ground, NET them, they don’t really show up as there is no connection between parts. For electrical design this makes no sense… because KiCad is build around a lot of preloaded components and rules, without freedom I am NOT too sure schematic is answer that can help. In first picture I showed a space between ground outline of the board(please note just ground) and fill area. And this is what I am trying to get rid off.

With this said if the only solution to use schematic and net, is it POSSIBLE just to net 2 lines and GND without any connection so when assigning the fill area GND net can be selected?

Maybe this will be better

Is your board outline on the Edge.Cuts layer? (It looks like it’s on F.Cu.)

If it’s on F.Cu then KiCad has no way of knowing that you want them to have the same net, so it tries to isolate copper.

If it’s on Edge.Cuts then check Board Setup > Constraints > Edge Clearance.

(The general way to solve things like this is to select the zone fill and the edge and select Inspect > Clearance Resolution…)

Hello, thank you for you response. Yes, board’s outline is on Edge cuts layer. I set both edge clearance and fill area to 0 but still no luck. But I think answer is close since doing an inspection it show Netcalss Default .2mm, please advsie on how to set it to 0 is possible. I assume this will fix my issue, thank you

I have hidden Edge cuts layer so not shown in this picture(white line left from previous) + Board Setup Window

I believe this is my issue, picture after inspection we’re progressing

OK I figured how to set default spacing to 0

It looks much better but still some area is missing coverage…

Board manufacturing preview

OK, so we have some kind of language barrier here. “an outline of my board(GND section)”, “border of fill zone GND outline of the PC board” etc. were confusing.

But I don’t know why you are using copper lines (it’s still unclear to me if they are tracks or graphic lines) for this. Why not just use the plain zone? You can draw it directly to a wanted shape.
