Three new primitives plugin for shell, spiral, gear

[PhilippePoupon]

Hello,

I try to add thickness to the shell but actually it's don't work ( I 'm a beginner in erlang ! )
I'll try to improve it all when I have more time

This is why I add the "Invert Normals" to create the inside of the shell !

If you want to hollow the shell you can use this trick :

you must create a second shell with same parameters except for section hight and section length who must be smallest, and invert the normal , this is the inside of the shell.
Then you must select the larger section of the two shell and use bridge .

For example:

First Shell for external :


Second shell smallest and inverted for inside :


Use bridge !

The result:
