Thank-you for that little nugget of code in (b) and in ©, why didn’t anyone ever suggest this before, that will save me some serious time in assembling these strings and pushing the data over to the html.

For the record I did via a very verbose PM critique of another plugin in DEC of 2017. (But it likely got lost within too much info at one time.)

This piece of code appears to be an efficient way of doing it but the problem I am seeing is that once I bring it into javascript I’ve got a string with all my parameters in random order

It is actually a simple example, but I’d encourage you to instead use JSON.

Going between Ruby Hash, JSON strings and SketchUp attribute dictionaries …

And the most comprehensive of my posts on going from Ruby hashes and arrays → JS Objects using JSON strings …

Calling methods in javascript through ruby

This is because your str object above is defined as an Array with 1 member, which is a Hash, which has several key/value pairs, the last of which is "projects", whose value is an Array with 1 member, which is a Hash. IT is not yet a JSON string. To use JSON functionality, you normally need to … require "json" … but I think SketchUp loads it up at startup anyway,… but you should still “require” it so as to declare a dependency. Then to produce a JSON string that you wish to send to a HtmlD…

Example of Ruby array to JS array:

So basically … from the Ruby-side …

my_ary = [[1,2,3],[4,5,6],[7,8,9]]
html_dlg.execute_script("Data = JSON.parse('#{my_ary.to_json}');")

… and afterward Data is a JS reference for a nested JS array.
(Note you may need to declare Data as a global var set to null first.)
