Can a light beam pass through a ZTG area? Yes or no?

I'll answer your question with a question. Is Schrödinger's cat dead or alive?

. . . or one for us simple-minded non-engineers. Where was the man when he jumped off the bridge?

On the bridge? No, that was before he jumped.

Okay, he was in the air. No, that was after he jumped.

@matt There may be an issue with this page because most images are blank except this one which shows up as an abstract painting....!

It is actually quite pretty
File-corruption on the server???

What bothers me is that I can create two individual bodies without issues, but I can't merge them into one body:

Yeah, this was an old issue we had early on. I'm getting those cleaned up.

Which illustrates why this is more of a software coding issue than it is a theoretical impossibility issue. It's nothing more than deciding how you want to deal with the numbers, make it a gap or make it material. Making it a gap or boundary makes the most sense. Two parts put together with a boundary with zero space between would be the same as "Zero thickness" where a boundary was placed at the point of the ZTG.

Think about the term zero-thickness.

Q: What is another way of describing zero-thickness geometry?

A: Hole

In other words, zero-thickness geometry is an oxymoron, which says nothing about CAD functionality. There are good reasons why we spend so much time pleading for this functionality, but the concept is nonsense.

I feel my brain on fire.
So what about Mike's situation now.

I thought it was one of John's Pictures.

If anyone was discussing if it was offside, or a red card, etc? my mate JohnJohn would shut them down.

It obviously [WAS|WASN'T] offside because that's the decision of the referee.

The question is moot. No matter your opinion - the parasolid kernel says it doesn't exist.

Can a plugin be written for this? so a trick to disable this feature.

Yes, but not in this application.

https://en.wikipedia.org/wiki/Quantum_wire
Carbon Nanotubes are one molecule wide. Atomized silver can be absorbed into a carbon nanotube to create a 1-atom wide nanowire, as accidentally discovered two months ago by university researchers. These 1D wires are intended for use in nanoarrays.

1-dimensional objects do exist, and you can google that term for lots more than you probably care to understand. That fact is irrelevant to CAD design, as it is not intended to apply to a quantum scale.

Yes, a plugin to start Inventor and shut down SW.

ZTG created in SW 2021
I cannot share the SW file. I saved it as X_T. SW will complain if you run import diagnostic.
