Hi all,
Is there any way to make curve route / trace lines in eagle pcb smooth?

Please see attached image, some edges are straight, while curves edges are rugged.

Thanks in advance

Photoshop. But I don't see a reason why rough edges would make a difference..

What do your Gerbers look like when the screen shows this?

I'd also be more concerned about the middle track pad entry than the edges referred to -I suspect that they would actually be smooth in Gerber land.

I think the term you might be looking for is anti-aliasing; Eagle doesn't anti-alias when exporting to bitmap formats. You'd have to either export to one of the vector formats and import that, or export at a much higher DPI, then scale it down in your graphics editor; note that this may make orthogonal lines a bit blurry as well without proper subpixel hinting in the graphics editor.

Unless it's just for display purposes, you wouldn't want things anti-aliased, though. If you were to print a bitmap with anti-aliased edges, the printer will have to use various levels of dithering.. which is not what you want when printing for e.g. home-made PCBs.

I also just noticed that the traces are not technically connected to the pads. Eagle is going to throw errors when running the DRC.

Hi, RiiC. Did you get around to making gerber files and viewing them? Sparkfun has a tutorial on now to export gerber files. Then you can use this online gerber view to look at them. Also, if you upload a .zip file of your project, me or someone else can take a look at what you have.
