I essentially just used the draw arc tool to make them. They are around 4" x 4".

Thanks for the help everyone. I tried the making diagonals method that was suggested and some really weird stuff happened. Basically after each diagonal the area between the diagonal and the external curve filled itself in, and when I made the final of the three diagonals shown the first picture the whole shape filled itself in. I then removed each of the diagonals and for whatever weird reason the shape still stayed filled in, as seen in the second photo. Just out of curiosity, does anyone have any idea why it stayed filled in after I removed the lines? In any case, thanks for the assistance.

How do I fill in the shapes that don't have areas in the attached photo? I want to fill them in so that I can use the Push/Pull tool. I don't know why the center six are different than the other four to the left and right. I even tried remaking these six but the area still disappears and they just become outlines. When I zoom in closely, I can see that each of the curved segments are connected, but still no area or fill in appears.

Hi,
I was wondering how you would smooth out the intersection of two 2D shapes' overlap. For example, if I had intersecting shapes like those in the image above would it be possible to smooth the interface circled in red so that it wouldn't have a corner i.e. a non-differentiable intersection point?

Thanks

Hi,
So I was wondering if it is possible to overlap 2 or more 2D shapes and then delete the area of one of the shapes to create an irregular shape. For example, if I had a two circles and I overlapped them (in a venn diagram-esque way), is there a way to delete the area of one circle so that I end up with a crescent?

Thanks

Hi,
I'm new to SU so I'm just asking a general question. Say I made a circle and used push/pull to make it a certain height and then made another identical cylinder. Is there any way to overlap two cylinders and delete one of them, thereby removing the space of overlap to create some kind of crescent shape?
