Hi Dudi0, Welcome to EasyEDA. EasyEDA works with rectangular co-ordinates so if you want to evenly space your LEDs on the circumference of a circle you will have to do some maths to work out the XY co-ordinates of each of the LED positions. This can be done using polar (angle and radius) to rectangluar (XY) co-ordinate conversion. One place you can find out how to do this is here: https://www.mathsisfun.com/polar-cartesian-coordinates.html Then you can place the parts at these co-ordinates by hand. If you are comfortable with creating your own scripts then you can automate the process using EasyEDA's scripting features: https://easyeda.com/Doc/Open-File-Format/ and: **Super Menu > Miscellaneous > Scripts...**
