Join boxes revisited

Hannes or some other genius:

I'm trying to achieve the exact same culling of duplicate surfaces and joining of boxes as in this thread: http://www.grasshopper3d.com/forum/topics/removing-duplicate-surfac..., but I can't get the join_boxes definition to work.

Loading it brings up an IO/event log warning saying "Missing object chunk in archive. An object could not be found in the document, it will be missing once the file is loaded." However, the definition looks like in the image Hannes posted, and I don't get any runtime warnings or old components strikethroughs.

It doesn't behave as expected though - the end result I get from trying to join two boxes this way is not one but two breps, and they don't have any cut outs in them. Attaching the files below. I've tried it both with boxes snapped to each other (which is what I'm after at the moment) and intersecting each other.

I'm sure I'm overlooking something glaringly obvious, and/or being silly in some other way, but any help would be much appreciated.

Thanks!

Hi.

In my opinion, this is not the case of culling duplicated surfaces because your large box doesn't have the same sized and overlaped faces with small box.

In this case "Solid Union" is more appropriate approach.

Thanks – it's just that, as with Connor Nicholas's comment in the original thread, there might well be (quite) a few thousand boxes to union, and I'm worried about computing juice. I'll give it a go though.

Cheers
