Hi, I’m new to Blender, and on this forum as well, this is my first post, I hope I’m posting it to the right place.
So then the problem I have: I have a cube with a cylinder inside, both of them are closed on the bottom and open on top. I’d like to fill the face on top too but only between the top verteces of the cylinder and the top verteces of the cube. When I select the top verteces of the cylinder - which form a circle - and the top verteces of the cube - which form a square - and then hit the F key, also an additional face is created between the top verteces of the cylinder, in other words the circle also gets filled. Then if I remove that face, the whole face is removed, so there are not two faces created only one. So… that’s my problem, image attached. Oh yes and one more thing to mention: of course the cylinder and the cube are one shape, not separated ones. A circle has been put on the top of the cube, I’ve joined the two shape with Ctrl+J, then extruded the circle downwards to half of the cube.
