Hi Rhino commanders,

I ask here about a very common and very mind-perplexing bug regarding the *failed intersection of two objects*.

If you have a few seconds, please see what happens in this video:

…intersection-related commands { *intersect*, or *booleandifference* } fail to yield the correct result (all intersection curves or the boolean result) at a particular ‘location’ in the model.

Why? Why does this happen? And why would it ‘go away’ if I slightly move the geometry a micro-fraction? I don’t want to move the geometry, I want the intersection to occur where *it is occurring*.

Thanks in advance for your answers

- edit:

using Rhino WIP, if it matters…but the issue is the same on 6 - and these are all water-tight solids - one big, many thin, fully intersecting each other.
