##### ZigZag pattern
« on: August 20, 2014, 01:10:21 AM »
I need to setup a shape representing an auger conveyor.
The length shall be infinitely adjustable and the height shall scale the zigzag pattern.
Infinitely adjustable length can be easily realised by a line pattern.
For the scaling of the auger, however I'd need a fill pattern. Unfortunately it doesn't scale in the Y direction and multiply in the X one.

I then thought about setting up the whole thing in geometry sections that would show or hide depending on the lenght of the shape and otherwise scale with its height. But that seems a little overkill for a task that simple.

Would anyone have an idea?

It seems Width of the shape must be n x Height x 2 / sqrt(3).
Here n = turns of screw, n = 1, 2, 3, ,,,

Got it! ... well one solution. And thought I'd share.
I like it because it is so simple, easy to maintain and flexible.
It is based on an image that scales with the height of the containing shapes and is otherwise croped at is width.
Enjoy.

Thank you Junichi, despite I didn't use your formula.
