I am trying to make the grid on blender round, like half a circle or similar. I'm trying to see how the magnetic fields will interact on a curve versus a flat surface. I wasn't sure how to do so, or if I was able to after already putting materials onto the existing grid. Help!

    $\begingroup$ There is no way to alter the grid on the viewport or put materias since is not an object. Create a grid object and deform it to your needs. Please edit your question and show a reference image of what you are trying to accomplish $\endgroup$ – user1853 Jul 31 '17 at 17:02
  • $\begingroup$ I don't have an image to reference, just wanted to see how the fields would be altered. How could I alternatively put the planes and forces on a half circle type object? $\endgroup$ – Kyra Toomey Jul 31 '17 at 17:04
  • $\begingroup$ Easiest way of doing what you want is to add a curve object, convert it to a mesh (ALT+C) and select snap to vertices. This way you can snap your objects to a curve. You can also use a cylinder, which is faster, but leaves a bigger object. $\endgroup$ – FreemoX Jul 31 '17 at 17:56
  • $\begingroup$ @freemox When I select ALT+C I only get Curve from Mesh/Text and Mesh From curve/meta/surf/text as options. Not sure if I added the correct curve object or not have a personal preference on that I need $\endgroup$ – Kyra Toomey Jul 31 '17 at 21:10

As mentioned in the comments, there is no way to change the grid pattern in Blender. A workaround to this would be to add a circle curve to guide you.

enter image description here

This process will convert the circle curve to a mesh, meaning it will have vertices like a normal mesh would, as seen in the screenshot below: enter image description here

From there you can enable vert snapping to align your object to the circle: enter image description here

As you notice, not all the spheres will align with the center on the vertices, to change this, you have to change the "nearest" option to "center" like so: enter image description here

Edit Asker requested this as a half-circle. This is easily achieved by simply cutting the circle in half. enter image description here

Hope this helps.
