@swiezak, Hello and welcome to EasyEDA. >Where can i set default colors of schematic? At present there is no way to set default colours for EasyEDA. However you can set the grid and background colours for each new schematic in the right hand properties panel. ![Background and grid colour selection][1] You can also change the colour, width and style of wires, lines and the fill in shapes in the same way. >second question- When I change something on schematic how can update board without new generating PCB? Click on the **Import Changes...** icon in the top toolbar of the PCB editor. ![Import Changes...][2] :) [1]: /editor/20150820/55d4f6d4706d0.png [2]: /editor/20150820/55d4f85290476.png
