# Bevel Curve Mesh modelling

I'm trying to model the image of this control knob which has a curve to it. I start off with a cylinder as shown in the example I've attached. select 4 vertices and make a face in the middle of the knob. But I also make another 2 faces left and right so I can make the bevel. When I select the edges and do make the bevel, as seen I'm getting some odd mesh result appearing. Is this the correct approach to model the reference image?

Thank you.

• Add a Subdivision Modifier. You will likely need to create a small extrusion to the top to keep it flat.

You could do it this way, you need to extrude, mirror, bevel, cut, join...

• Hi Moonboots, Thanks for your example, that control knob looks awesomely modelled. I'm just a confused how did you make the join faces, I cannot figure it out, so I can continue on. if it's not much of a hassle for you, and do find free time, could you please do a quick demo tutorial how you made this. Kind regards. Oct 24, 2019 at 5:49
• what join faces are you talking about? After the bevel you just need to join some vertices (J) and delete some edges (X > Dissolve Edges) Oct 24, 2019 at 7:54
• I thought I had uploaded the image.... Here is what's confusing me. The second step: ibb.co/NLKxbZ3 How did you get the quarter Cylinder? Oct 24, 2019 at 8:47
• I made some progress, I figured out the mirroring, and would like to know how you got the shape which is within the red rectangle. ibb.co/tBHmX6v Oct 24, 2019 at 10:55
• you need to select the edge on the corner and bevel with ctrl B ;) then you'll make some manual corrections: zupimages.net/up/19/43/bmd1.jpg Oct 24, 2019 at 11:08

Try dissolving the coplanar faces (the vertical side and the face on top of it). Worst case scenario you could do it with a boolean operation on a basic cylinder and the knob profile.
