This feature is not supported on EasyEDA. It is however a good idea and one that has been discussed before. May I suggest that you raise this as a Feature Request? That will help push the idea a little further up the ToDo list. :)

Hello Andy Fierman, It seems to me that if you give in the schematic that this line is a power-line, for example 12Volt 2Ah. Now this line is treated like a regular line, if you update it to the PCB editor and you do an "Auto-route" then the lines run nicely and it all fits. If I then make the power-line thicker then the total does not fit anymore and I have to do it manually, which in turn means that I have to make bridges everywhere to get it working. I have to say that I only make single-sided PCB.

In my opinion, it is of no use that you indicate the line thickness in the schematic. My excuse for any grammatical errors, English is not the language that I manage well.

`In my opinion, it is of no use that you indicate the line thickness in the schematic.` That is not quite true. :) It is true that changing the wire thickness or colour has no *effect* on the PCB but it is still very *useful* as a way of reminding the person who is doing the PCB layout that there are some things in the PCB design that may need special attention.
