trying to work out orientation of a plane in a for loop, getbbox_size giving me a size of 5 for a completely flat ZY plane

even if I move it back to i still get the wrong size. No other primitives there, so strange!

Why do you say it's the wrong size?
No one can tell by just a screen shot since if the bottom of your grid(y-axis) is not even with world grid,
it will make it seem like a different length visually because of the perspective.

Post your hip.

That's floating point notation, 5.07832e-5 is 0.0000507832 or rather a really small number.
It's a precision issue, not much you can do about that.

kept looking at the 5 and didn't even notice the e-5 - now I feel dumb!
