I'm trying to model a database symbol like this

enter image description here

The only way I currently know how to do this is by starting with a flat cylinder and repeatedly extruding and scaling.

extrude scale Z scale .9 extrude scale Z scale 1.1

enter image description here enter image description here enter image description here

This is very tedious. How else could I accomplish this?

create a single piece out of a cylinder.

To make the edges less sharp read this question:

Weird deformation between large ngon and edge ring

Add an array modifier, and move the relative offset values for the Z axis like this.

Add a mix of glossy and anisotropic shaders.

EDIT Want an even simpler way?

Add a Curve->Circle.

enter image description here

enter image description here

Make it a 2D curve, fill in on both sides, give it some extrusion and bevel:

enter image description here

Add the array modifier, and texture.

  • $\begingroup$ That works perfectly. How did you get such uniform lighting over the object? $\endgroup$ – spuder Oct 17 '14 at 5:08
  • $\begingroup$ For the lighiting you just need a big source. Either a large plane or something like this: blender.stackexchange.com/a/15685/1853 $\endgroup$ – cegaton Oct 17 '14 at 5:11
