----SOLVED----
Thank you to everybody for your assistance. I managed to get to where I wanted thanks to instructions provided by @dual_sport_dork
Thank you, thank you, thank you!
Not sure if anyone can help me here. I am pretty lost and confused and wouldn't mind if someone could ELI5 something for me.
I've never used a real CAD software before yesterday night and I'm struggling a bit, I tried googling things but it's just sending me deeper into a rabbit hole of things I do not understand yet.
I'm trying to make this speaker enclosure I've seen just to do something with this shitty bluetooth speaker I have, so I decided to recreate the enclosure myself.
Long story short, I realized I kinda screwed myself after disassembling the bluetooth speaker and now I need to make a 2mm deep pocket on top of the case to snap in the buttons module. I don't really feel like starting the design again from scratch.
Anyway, as you can see in the attached image, I need to make a big round pocket on top, but both side panels are separate bodies so my pocket only goes through the main body and ignores the 2 other bodies.
I can think of other ways to achieve what I want but I'd really like to figure out a way to do it from where I am right now, if possible. I've seen the term shape binder and "union" in my searches but I can't quite figure it out.
Thank you to anyone who bothered reading this lol
EDIT: For anyone who might see this and is curious about how the enclosure is performing, I finished printing the main body and assembled it to test. Am still missing the side panels and I have to design some kind of flange cover for the driver but here's what I got so far:
I don't know about the right way to do this, but here's what I'd do:
Go into the Draft workbench. Select the sketch for your pocket circle there, and create a Draft Clone of it, which is the blue sheep icon:
This is not the same as the orange sheep "Partdesign_Clone" command found in the Part Design workbench. Don't ask me why they use the same icon.
If this is the first time you've used the Draft workbench, it will "helpfully" slap a grid on your X/Y axis. If you would like that out of your face, click the "Toggle Grid" button, which may be in your overflow toolbar and has thus fallen off of the right edge of the screen:
Anyhow, this will create a linked clone of your sketch. Anything you do to the original will be reflected on the clone(s) if you have to adjust it later. Create two clones, since you need to apply this to two bodies. Drag one each onto the bodies for your side panels (their root icons are that blue stairstep logo). You can then use these to create a pocket or pad or whatever you're going to do.
If your side panel bodies have their origin set to the same position as your baffle piece in the middle, you won't have to do anything else. Your cloned sketches will be in exactly the same location as the original. If you moved them relative to the document origin, you may have to scoot your cloned sketches around by fiddling with their coordinates in their Attachment properties.
I have no use for these instructions but wanted to say thank you for taking your time to do this. I have been in this type of situation countless times and would kill for a response like this. Thank you for being helpful and useful to someone in need.
Wow, same here. Upvote just for explaining how to turn that dang grid off!!
