How can I create a circular power supply trace?

e14 Contributor

Hi,

I have 40 LEDs arranged radially in a circle, with the anodes all pointing towards the center of the circle. I want to connect the cathodes to Vcc with a fairly heavy power supply trace, but I can't seem to figure out how to do it. I can't rename a circle created on the top layer to "Vcc", and that was y only guess!

 

Any help would be appreciated.

 

Thanks in advance.

    There are a few ways butthe most correct way should be as follows.

     

     

    Assuming you have airwires connecting the 40 LED anodes and they are all on

    the circle (9 degrees apart).

    Check HELP for the use of the wire tool and the CTL key to specify an arc

    wire. This applies to ROUTE as well. This creates arcs, you will make 40 of

    them.

     

    Place a MARK in the center of the circular array. This becomes your easy

    reference.

    With ROUTE active, click a LED anode.

    Move the mouse to the MARK, depress the CTL key and left click. A large arc

    will form

    Move the cursor back to the next LED and click on the pad. The short arc

    painted will be of the correct curvature.
