Making 3D Bullet CaseLathing in Cinema 4D
First you'll need to know what the case looks like. There are different parts of a cartridge, but once used, they separate. Although many people call the pieces by incorrect names, the bullet is the part that comes out, the projectile. The pieces that are most commonly requested are the case and primer.
The base is usually the brass part and the primer is the bit which the hammer hits to ignite the charge, sending the bullet out of the cartridge.
Cases all look different depending on the arms that they are designed for. Jewelry designer site bulletforge.com has some nice pictures of inert jewelry bullets.
Use an image to trace if you need to. We'll only need the profile of the case.
Select the FRONT or RIGHT view to view the reference (if needed). Use the spline tool to create the outer profile of the casing, starting at the bottom of of the shell, X=0, and tracing your way toward the top.
At the top, stop. Use "v" on the keyboard to pull up the contextual HUD menu. Select "Create Outline". The Attribute window will change to reveal the active tool's parameters. At this point, you may want to choose to create a new object. Change the distance to 1.5 and click "Apply".
With the new spline selected, Option-select the LATHE NURBS object.
Optionally, you can add a primer (cylinder) that will stick out of the bottom of the lathe.
You're finished modeling. Next is texturing. Fortunately, your copy of Cinema 4D came with several materials to start with. Metal 007 is a good material to use as a base. Remove the Environment property by turning it off in the Basic Properties window.
Add a simple white texture to the primer. Add a little bit of metallic reflection to the primer texture.
