# How would you curve the edges of a 3D shape?

I have a basic shape that at one end is wider than the other, the object gets thinner basically but the edges of the shape are straight, instead i want them to bow inwards.

Picture to demonstrate what i have and the red lines show what i am aiming for:

Is there some modifier for me to do this? Not sure i can see an easy way to do it manually.

• You can't curve edges without subdivision – Duarte Farrajota Ramos Sep 20 '17 at 19:40
• @DuarteFarrajotaRamos does that work for 3D objects too ? Seems to only show how to do it for a 2D plane and that it does it to all 4 sides. Converting to a curve does nothing for it. – Dave Sep 20 '17 at 19:47
• Add some Subdivision as Duarte Farrajota Ramos suggested and use Proportional Edting (Found just above the Timeline). – Dontwalk Sep 20 '17 at 19:51
• @Dontwalk but according to the answer that was linked above you only need to subdivide once. But the answers he linked to only works for a 2D plane it seems since it doesn't let me apply any curves to the 3D object when i apply scale to the central vertex. – Dave Sep 20 '17 at 19:57

Here's a 3D version of your Plane.

Add some subdivisions by pressing CTRL + "R" The more subdivisions you use the smoother the curve you are after will be.

Select two edges (You could also do one at a time). Turn on Proportional Editing and choose a "Falloff" type. I choose "Smooth" here.

Press "S" to scale and the Axis you want to scale on. I pressed "S" + "Z". Use the mouse wheel to affect more or less vertices.

Add a Subsurface Modifier and "Smooth Shading" if you want a smoother look. *You can use the same method with a plane.

EDIT You could also do this with a "Bezier Curve". Create your shape and change the curve to 2D to fill the shape.

• Oh i see, thank you :) I was selecting edges incorrectly. This was very helpful. Thanks again! – Dave Sep 20 '17 at 20:34
