Can you not set tracks to free draw in the right hand Canvas Attributes panel? Canvas Attributes > Other > Routing Angle [https://docs.easyeda.com/en/PCB/Canvas-Settings/index.html](https://docs.easyeda.com/en/PCB/Canvas-Settings/index.html)<br> <br> And on the fly: [https://docs.easyeda.com/en/PCB/Route/index.html#Some-Tips-about-Track](https://docs.easyeda.com/en/PCB/Route/index.html#Some-Tips-about-Track)

Tracks can only be straight lines or arcs in EasyEDA, cubic or bezier curves are not supported und must be approximated using short line segments. The alternative is using the image/svg object, which actually supports cubic and bezier curves, but you will loose some features of native Tracks, like DRC rule checks etc... Either way, there is no usable interface to draw these curves in EasyEDA, so I actually suggest using my extension [https://github.com/xsrf/easyeda-svg-import](https://github.com/xsrf/easyeda-svg-import) to import the layers from an SVG file which you can draw in InkScape or any other SVG editor. It can import as SVG node with native cubic/bezier curve support or import as tracks using small line segments of a given approximation.

Oh and you can also import as solid regions which also support cubic/bezier curves. Solid regions do have the benefit that you can at least assign nets to them (which you cannot on images). But be aware that they do not support shapes with holes! So you cannot use them to model tracks that have loops.

The free draw I was thinking of is "Free Angle" which produces sharp corners. The Arc 45° and Arc 90° options may be more useful: 

Thank you all, your suggestions were very useful. I've got the best results with the Andyfierman suggestion, is very easy to use and reflects the look I need!
