Hi, I have been using EasyEDA for about a year, and it's a great circuit design tool, with all stages of design in one place, and a bunch of other features which I seem to be blanking on right now, but there's something that's been bothering me: When you have a project which needs multiple boards, you either use multiple projects, or you do what I've been doing for the last 3 months: Keep note of which sheets belong on which boards, and for each board delete every component that isn't on those sheets. (I select everything on a given sheet, move it out of the way, then when I'm done delete the original block of components, to work faster.) Going back to the multiple projects thing, which started about 8 months ago when I tried making my own Cube-Sat, I had different projects for each board, but it was fairly cumbersome to find them short of pinning them, which causes problems when you try to work on other projects. So, my suggestion is to add folders to store multiple projects in, like {Cube-Sat} -> {Power Supply Board, Processor Board, Radio Board, ...}. This is particularly relevant now as I've started another multi-board project: A 14-bit calculator with a decimal keypad input and decimal output, signed, with addition, subtraction, multiplication (provided each number is under 128), and a memory function (store, recall, clear, add ACC to MEM, subtract ACC from MEM). I tried this in ExpressPCB, where multi-page schematics fit into a single file, but PCB routing was a bit confusing since there was no rats-nest layer. And now thinking about what I've just been talking about, I realize there's technically two ways to solve this problem: Either add the project folders, as I was talking about, or make each schematic take a single file in the project manager, and have new PCBs use only one of those files. ~ Wesley
