Select the silkscreen layer. Select the trace drawing tool on the PCB Tool's palette. Draw your rectangle.

It's works. Thank you very much!!!

@andyfierman there is no "trace" tool in the PCB tools palette (version 6.2.38 2019/08/20)!!! Tried "rect" tool - cross hairs appear but square not drawn!!

@andyfierman This ONLY works (picking rect tool) on the top silk, but NOT the bottom silk layer.

@bobs.spamfilter please check above Andy said

@UserSupport Thanks Andy. I realised what I was doing wrong later. It was my first ever use of Easy EDA and I hadn't noticed that I had inadvertently turned OFF the view for the top layer and the bottom silk layer and was thrown by trying to find the "trace" tool and never thought about a small typo - trace to track - despite years of engineering coal face work following PCB "traces" ... DOH! Struggled through however and more or less completed the board I wanted to make. A bit more practice and I might even get competent! LOL BIG change from when I used to design boards back in the 70's using 2x and 4x scale Chartpak pads and tapes! Still have a couple of original drawings floating around somewhere and several positives and negatives of others after photography and development!

@bobs.spamfilter, Autocorrupt has a lot to answer for. Or I probably just forgot the tool name. :) Have you explored (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) ? My first PCBs were done using Chartpak and draughting film or, for the rough ones, Dalo Pen. :)
