"btw: You can doubleclick on the canvas and just type to find a component by name. This won't work for if the component isn't called as you'd expect of course ;)"

"Sorry for confusing you. The component I was referring to is CullIndex. The result of the comparison is just a boolean value that says "true" if A is larger than B and "false" otherwise. Those values convert to 1 and 0 as…"

"My apologies if I'm being a pest. This is what I've got now. But I can't just delete the results of the Larger Than right? That's just a list of areas, not pointers to the objects themselves. How do I relate…"

"ListItem was the hint I needed. I can't find a DeletItem component. This is the biggest difficulty I find using GH. If I know a component exists but don't know exactly what it is called or where to find it in the palettes,…"

"Same logic applies to a list even with only two items: You'd need to compare A to B. That means extract the first item and the second (ListItem). If A is smaller than B, delete B, otherwise delete A. (here's a trick with booleans: true…"

"Hi Hannes, I only need to compare each pair of surfaces (0 and 1 indices) not the entire list to itself. Then delete the larger of each pair. Eric"

"GH and coding sometimes makes you think in different terms and stategies. Building a definition is like chess: you have to think ahead a few moves. What sounds reasonable in the first move may lead nowhere further on... Larger or smaller than needs…"

How to compare and select objects

Hi, the image represents areas of a number of split surfaces. How can I select the larger of each set for deleting? I'm confused about whether I use the List components or Tree components to access the data.It seems like I should be able to input the list to the Larger Than component, with one input shifted but that is not doing the trick.Eric…See More

"I can set it up so the outside trimmed surface is always larger, and sort by area."

"I wish it were that simple. The centroid of the keepers is not necessarily inside the BRep. Think of curved slices of a 'J'-shaped pipe that are offset from the CL of the pipe."

"That works well, thanks. Now to sort out the split surfaces that are inside the solid from the ones outside. "

"Then you should also use the shifted list as an input to the trim surface component. Or you should generate the offsets with a Series starting from Ply t. That way you will not get the original surface in the first place."
