How can I divide a rectangle, representing piano keys to be sawn from a panel? The panel has a short (Y axis) front section ,equally divided for the natural keys, then a second section the narrow portion of keys visible to the player, not an equal divison of the keys in each octave, repeated in seq…

I should have written ‘specifying equal, or a repeated varying sequence’

I should even better have written ‘specifying equal, or a repeated sequence of varying widths’

it sounds like something which you should draw by hand if its not an infinite amount of keys which you want to display. array may help you to get the numbers of octaves and the rest you adjust manually for example… if you want it more dynamically grasshopper could help you set up an algorithm for di…

The variety within each octave is fixed, repeating as necessary. What I want is to have panels printed with the lines before sawing, rather than spend a disciplined hour on each panel drawing manually. I know a colleague who does just this with rhino, but he is being coy.You used the word ’array…

Richard Z, thanks mightily! ‘Array’ is the word, and it does everything but calculate even divisions - the intervals must be specified. Fair enough - I have a handle on it, now. Good news in Bohemia

looks interesting, keep us updated if you want :slight_smile:

seems the only way to learn this program is to crash through it learning a code of strange protocol that will in 147 years become second nature. Ouch, no need to worry - everybody learns Rhino, and so say all of us.

Richard Z, here is a keyboard, showing better than my description the
different sections in the layout of the panel. Thanks for your help. P
