Dynamic Bloc / array

[sam.connolly]

I'm trying to improve my skills with dynamic blocks and arrays within AutoCAD LT. 

I want to create a dynamic block for the setting out of screw and dowel holes for a cabinet (just circles). The first and last holes should be set 50mm back There should be a minimum 100mm and maximum 200mm between the larger holes. 

For starters I'd really like to be able to first create a block or array that as I stretch from one end it keeps the sets of holes evenly spaced. Taking things a step further I would really the block/array to add another set of holes when the spacing exceeds 200mm and remove a set of holes when it the spacing drops below 100mm. 

I think  unsure of the best way to achieve this without parametric constraints- either dynamic block or array, and I'd apricate any help/advice. 

Thanks in advance!

Attached two example blocks.

The one: the distance between the holes will never be smaller than 100.

The other: the distance between the holes will never be larger than 200. 

(You must decide yourself which of the variants better meats your goal)

Give it a try. 

(I hope ACAD LT can do the job, I can't test it)
