I want to create a magnet out of a cube (prefer not to use any curves for this one).

I have extruded the cube to the following shape:

enter image description here

And added the subdivision surface modifier to get to this point:

enter image description here

Now I would like to make the left side rounder so it wouldn't look so boxy. Something like this reference photo: enter image description here

How could that be possible?

    $\begingroup$ well, the best is probably not to begin with this shape ^^ $\endgroup$

Even if you use the bevel operation to round the edges, it will probably fail because the faces will intersect.

If you want to create a magnet shape without beginning with a circle, you could create a cube, stretch it, duplicate, move these edges to tilt the end faces:

enter image description here

Then select the faces and CtrlE (Edge panel) > Bridge Edge Loops:

enter image description here

Tweak the factors in the Operator Box:

enter image description here

Or use the Spin tool (press Ctrl to rotate 5 by 5°), and extrude at the end, again you can tweak the parameters in the Operator Box:

  • $\begingroup$ @Robin Betts it doesn't always work if the faces are not a bit tilted, or I miss something $\endgroup$

  • $\begingroup$ How to avoid that? zupimages.net/up/23/17/b1l6.jpg (on the opposite faces it works fine) $\endgroup$

  • $\begingroup$ Wow. Infuriating! I've tried flipping normals in weird ways, moving origins, orienting everywhere.. and can not reproduce your flipped arch! ( I was originally thinking of bridging filled faces with correctly oriented normals, anyway) I guess that proves your point. If I wanted it to go the 'wrong' way, how would I tell it to? $\endgroup$

  • $\begingroup$ It doesn't happen if I select the opposite faces, I'm not sure the reason why: zupimages.net/up/23/17/nlu9.jpg $\endgroup$

This is a great example on the importance of the edge flow... I imagine moonboots will post a great modelling answer momentarily, so meanwhile here's how it can be done in geometry nodes:

You can then apply a modifier and add loop cuts with ✲ CtrlR, or without applying a modifier, you can add a bevel modifier with 2 segments and Subdivision Surface modifier with 2 levels:

Or good old modifiers, using four vertices.

Start with a cubecube

then scale it (in edit mode)scaled cube

now we can bevel some edges like so beveled cube

and I know this might be cheating, but we can merge a cylinder and a cube with the boolean modifier like this.boolean

we can then use the boolean modifier again to cut out the center of the magnet.this

and we get this:like this
