Boolean Modeling Tool cinema 4D

First start by making a Capsule. Objects>Primitive>Capsule.

Step 2

Make the settings like I have shown below. Then click Apply.

Step 3

It should now look like this.

Step 4

Duplicate the capsule (copy and paste). Make the coordinates of the duplicated capsule (Capsule.1) look likes the settings shown here. Then click apply.

Step 5

It should now look somewhat like this.

Step 6

Now apply Boolean by doing this...

Step 7

Or another way is...

Step 8

Now put both Capsule.1 and the orginal Capsule into Boolean.(Make sure the original Capsule is ABOVE the duplicated capsule!).

Step 9

Now your image should look somewhat like this.

Step 10

If you dont like the way that looks, just move Capsule.1 forward or backward. (USE THE GREEN ARROW!) 

I changed the coordinates for Capsule.1 to... and then applied them.

Step 11

If you use the settings above, it should now look something like this:

Step 12

Now just goto Render>Render veiw to see what you got. 

I added some materials, a plane, more boolean bojects, and lighting. I then came up with the below render.

Step 13

It may be a bit sloppy, but add some hyperNURBS( Objects>Nurbs>HyperHURBS) and you can make some renders that look great.
