Okay,I know your meaning: There should be a fit distance to set. Thanks, kubeek.

If you think of the fill as a vector rather than bit map, the fill is with lines that touch. The thicker the line, the more jagged will the edges be. The thinner the line, the more processing it takes. Eagle used to have a warning to that effect. Line width does not affect the gross appearance of the filled areas in Eagle, unless you pick the cross-hatch option.

Just to clarify, there are multiple ways to do what you asked in your first post. Your later post on page 2 illustrates one of the problems of using isolate as the variable. Of course, you can avoid that by using multiple polygons. The restrict method avoids that too, and I find it easier to do in a controlled and precise manner. In Eagle, isolate and line width can affect other things too, like the the way thermals are made.

Finally, as to the patch of copper that is not connected to anything, that is called an "orphan" in Eagle. You can choose to have them left in place or removed.

BTW, Are you actually a PCB manufacturer or is that just an avatar you like?

Thanks for your reply. I can know in Eagle there would be some set options for it. In PCB plants like us, the "orphan" was given the name "Island".

Yes, I'm working in PCBWING.com which is a online PCB manufacturer. But this is not an AD, at least before I become to a supporter of this "electro-tech-online" forum. Also we do not send Spam. I‘m here to make new friends, and also hope to maintain contact with the circuit professional technical personnel. Thank you very much.

One thing to consider when using "isolate" to prevent the thin lines is that you may cure the problem is one area and create another somewhere else, particularly on complex PCB's. Using a restrict layer will not have that global effect.

Yeah, the tear-drop pads are useful. I saw many designs use it. If designers use the old version software, they could request the PCB house to add it. But it should be they done the copper pour before. Otherwise it would happen short circuit. Like this.

Hi PCBWING,

it really drives me crazy to see so many posts for such a simple PCB layout stretching from Christ's birth till now!

There is absolutely no reason to keep traces that closely together as done in your layout!

Many traces could be drawn in a straight line from start to end - except for one. That one has to be rerouted to go around other pads.

Keeping safe distances between traces makes soldering a lot easier - thereby avoiding possible shorts between traces and/or pads.

When there is enough spacing between traces you might perform "ratsnest" setting up 0.4064 or 0.6096mm between ground pour and traces/pads.

Thanks for your "Hi" and so a many faces. I am worried that you did not understand the drawing. I do not think everyone agrees that these posts are useless. In many designs, there is not enough space for designers to draw a straight line, like this.

In addtion, curve is useful. I believe that it would be better if electrons run in a smooth curve.
