Advanced Block

Hi!

I've long wanted a set of blocks that had a quantity of "intelligence" - but I could never find the time to learn the programming API. Recently I was introduced to the power of dynamic blocks - and I'm quite excited!

I've got much of what I want implemented - I need some help trying to finish it up. There are actually several questions contained in this post - please bear with me.

First of all, there's a quantity of geometry that needs to be changed depending on a selection. This seems to call for a visibility parameter - and seems to work well. While I'm at it - I should ask if I've implemented this the "hard" way or not. The main geometry that gets affected is a square hatch area - depending on the visibility state, the size of the hatch with its outline square changes. There's no direct numerical relationship between the visibility state name and the size of the square. So I have a dozen states named "15, 30, 75, 110, etc." and the geometry should then be 20'x20', 30'x30', 38'x38', etc. At this time, I've implemented this by creating a number of simple blocks each containing the square hatch at a given size. I then block'ed all these together and toggle them with a visibility state.

Now, after I've selected the visibility state, I want to both have it available as an attribute and display a text on the block. I have no idea how to link this with an attribute - and the only way I now know to get the text to display is to generate a dozen texts and control them via the same visibility parameter. Is there a better way? And how can I set an attribute value from this method? I should add - the reason I want to set an attribute value is to later extract that information for counting purposes.
