[Others] How to ground the mechanical pads of a part( in Eagle)?

Hi everyone,I'm making a device with an SD card slot. The SD card holder is just a surface mount metal shell, and it has 4 foot pads that solder down, and are not electrically connected. I'd like to ground these, for the sake of shielding the card better. Is there a way to do that? Eagle won't let me connect anything to those pads.

[Others] How can i copy the format of the first rep_sht to the two other rep_sht?

Hi,I have a design containing 3 identical circuits in a repeated sheet (let's call it rep_sht) which contains a couple of subsheets. I would like to layout the first rep_sht and be able to copy the format to the 2 other rep_sht. Unfortunately Altium is making an individual room to each subsheets and only allows me to copy those ones individuall...

[Others] Is this ok? Copy from one kicad schematic to another kicad schematic

There is a portion of one project's schematic that I would like to copy into a different schematic in a different project. Is this possible? If so, how is it accomplished? (Selecting the portion, executing a Cntl-C, closing the first project, opening the second project, and Cntl-V does not work.)
