Hello! This seems relatively easy to model in SolidWorks, but I am pretty new to this program and am not sure how to do it.

It is simply a circle with some thickness that is curved upwards at the ends but tapers a bit as pictured.

In the same vein I want to end up with these forms attached to one another as shown below but I am also not sure how to do this.

(Is there another program that would be easier to work with for this?)

Any help is much appreciated!

The diameter of each circle is 7", 6", 5", 4", 3"

And the thickness is 1/16"
