How to curve a cube mesh around a circle perimeter I have a simple cube mesh that I want to modify so it will wrap around my circle's perimeter by 90 degrees like I have drawn here acting like a curved wall piece:

I looked in modifiers and tried Curve modifier but was not sure how to use it, does any one know how to do it ?
You can use the &quot;spin tool&quot;.
Start with a plane section.
Place the 3d cursor at the center of the circle.
Use the spin tool which will be placed at the 3D cursor location (thanks for the information, Robin). By default, the tool will rotate around the Z axis.

Once the operation validated you can tune the values, such as the number of extrusions and the angle.
