Use 'eq' to test if entities are the same.

Code: [Select]

(setq e1 (car (entsel)))
<Entity name: 7ef61e10>
(setq e2 (car (entsel)))
<Entity name: 7ef61e10>
(eq e1 e2)

Rude dog, I wouldn't know if you need sleep but not necessarily for having asked this question. It's a very good question which can cause quite a few errors when one doesn't bother to ask it.

Equality doesn't always equate equality when it comes to programming.

All have distinct differences

In other words, they are not equal.
