* Subject: Re: 3d sea-shell * Date: Mon, 30 May 1994 16:01:46 -0700 (PDT) [50] * From: Jeremy White <jwhite@efn.org>This is how I made a 3-d snail shell.
1.) Create a spiral path
a.) Add an axis with a point in the x direction.
z
|
y---x . <-point
b.) Extrude to a VERY small distance along the y axis, while
scaling up and rotating several multiples of 360 degrees.
This should give you a spiral path, try playing around with how
much you scale and rotate the extrusion.
3.) Create an extude template
a.) Create a disk primative
b.) Delete the center point.
(I also made an edge flat, so that I could overlap the shell rings
better.)
c.) Make sure that the y-axis is pointing up through the disk (x
and z to the sides of the disk)
4.) Extrude the disk along the path (1) (Scale it bigger through the
extrusion if you desire this effect.)

Add a primitive tube. Accept the defaults. Go into pick points mode and delete
the top row of points.Then, move the axis(only) by 50 units in X direction only. Then scale the object in x by 1.5x.
Extrude the object as following. To length 1-10 (or more, it is up to you). No. of sections - 36. Y-rotation 720 (or more), X scaling - .1.
This should give you the right shape. To make it 'bent' use Conform to Sphere option.
