Dynamic Block Array of incrementally increasing size

[Anonymous]

Hello,

I'm having quite a bit of trouble with a model I'm working on. 

I'm actually not allowed to post my model for work reasons, but all I want to do is to array a rectangle vertically (y-axis) along a single linear parameter every 100mm as an increment: easy, I can do this in my sleep..

However, I also want my rectangle to increase in length (x-axis) by n+150mm, where n is the number of array blocks I've added; effectively looking like a bar graph of increasing size as I continue my array

edit: just to clarify, the Stretch action when chained to the main Array action does not help as this affects all the new array blocks equally, leaving all of them the same length as I add to my array. 

please help

All the objects in an array are the same.  That is what an array is.  If the objects are not all the same, it is not an array.

You could do the end result you are looking for in a limited way by using visibility states and a double lookup to switch the state based on a linear parameter length as each new item should be shown.  Lots of work to do and would be limited by the number of visibility states you want to make.

Thank you for the insight Libbya,

would it be possible to see a small example? something simple with basic rectangles and 2 or 3 visibility states?

regards,

I will admit a bit of reticence to create and post an example when your organization is unwilling to help me with creating that example by posting a block to play with first...  To create the block from scratch is a drag and puts all the burden of time on me.  Just something to consider.

thank you very much! I can definitely use this method for my work. sorry for not being able to prove blocks for you to use, but I greatly appreciate you effort
