I’m trying to make a wall cladding with varying heights, I have used RANDBETWEEN(bottom,top) to get the different height of the panels, but I am unable to get the same value to the z-coordinate so the placement is off. It works if max.height and min.height is set to the same, but f***s up if not.
I hope someone can tell me what I am doing wrong, and talk like to a five-year old; I do not have extensive experience with dynamic components. 
are you trying to make each panel a different height? and a stack of them for a given wall height? one option is to define the general space for each panel - e.g. if i have a wall 12’ high, and i want 6 panels, then i have 6 “spaces” of 2’ each. then my panel component has a “panel” and a “space” component. the random function defines the panel z within the 2’ limit, and the “space” is the remainder. then i simply stack them. if i want the random heigh panel somewhere random within the space, then the space component has 2 copies - top and bottom and the panel sits somewhere in that 2’ space.
see example:
example random wall panels.skp (169.8 KB)
in this example the “frame” and “spaces” are hidden but could be other things like depth variations between panels or backing etc. one note - the wall panels will change each time you make changes to it – so once you have the pattern you want - de-DC-ify it (see Eneroth’s plugin)
Thank you! Now I have it working the way I wanted to.
