1. Blend with endpoint vectors (line segments), then rotate end vectors to adjust curve.
2. Clothoid script, adjust curve with sliders.
3. ellipses, parabolas, freehand...
4. Spiral scripts.

Hi Lara, you can use the Transform > Deform > Flow command to bend a flat base shape into a circular form.
There are details on it in the help file at
http://moi3d.com/3.0/docs/moi_command_reference8.htm#flow .
For bending from flat to circular it's easiest to do a curve-to-curve flow. That's where you will set up 2 curves for making the deformation, the base curve will be a straight line and the target curve will be a circular arc. Then Flow can map your object from the straight-line "backbone" to the arc backbone.
To get it symmetrical you may want to build the arc first and then make the line from that using the "UnwrapCurve" plug-in which will make a line that is the same length as the arc curve. You can find UnwrapCurve at:
http://moi3d.com/forum/index.php?webtag=MOI&msg=5136.1 .
So for your case you would set up a line and and arc like this, have them placed on the same plane:
Then to perform the bending, select your flat plate main object, then run Transform > Deform > Flow. At the first prompt it will ask you "Select base curve or surface", select the line. At the next prompt for selecting the target curve select the arc. That will make a result like this:
Hope that was what you were trying to do!
