I’m following along and around 8:06ish when you select the faces and inset them, yours move as one item but mine don’t? It splits into three insets, one on the curved notch bit and one on either side.
Image because I’m not sure how well I’m describing this
I get a 404 error if I try to edit so I guess I’ll reply instead. You can see in the picture, also, that individual is not on so its not that. I tried turning it on and off too in case it was acting up and behaving like it was on when it wasn’t but its not that either.
I’m stuck on the same thing. Insetting the cartridge box splits faces individually. Tried merge and Ctl N, even attempted joining and filling fasces, that was a mess. I’m tempted to go rouge and cut out the faces and go with a single face.
