This is about?

Hey Yes, I'm now to this instance. I'm also new to Lemmy I'm also new to CAD. What exactly is this community instance about? I LOVE guns, but what about CAD? Is that for 3D printing or acutally like machining metal and stuff?

Also can I be active in communities extept this one and create posts on them and stuff? The rules about that has been unclear to me.

Have a swell gun!
