Sketch-A-Graph type of hinge deformation
I'm sure I'm going to give Emmanuel a head ache with this one...

Imagine a ladder where each step is connected to the sides with hinges. This means that if you lift one side all steps go along and if you lift far enough the steps will be almost vertical and the side almost touching.

This is a real world, existing product:



And of course I'm trying to create an object like this. I tried just about everything I could think of but I can't get it to work, not even close. I studied the MultipleAxisTest example and reviewed the flexiblehose. I tried combining the correct parts to the double hinges. Using the "_and_" between doubles. In most cases Sweethome3d can't even import the object and when it does it sometimes shows an incomplete "modify openings" dialog. I can't even get it to work with a single step between the two sides.

Am I doing something wrong or is this just not possible?
