3D sketch mirroring - Is it ready!?

[Beyondforce]

Hey guys,

Just wondered if the 3D sketch mirroring feature is up and running?

I have tested it and the mirror works in the opposite direction 😯

@jeff.strater  - Any thoughts?

Thanks.

as far as I know, this is not expected to work at all...  I can't say I've ever seen anyone try that before - mirror in 2D and then drag geometry off the sketch plane.  I was surprised that it didn't remove the symmetry constraint.  But, that is an interesting behavior.  We'll take a look at it.  Sometime down the road, we'll implement a true 3D mirror (about a plane, not a line), but for now, I would not expect that to work, and it clearly doesn't work right...

I saw the "3D sketch mirror" in the roadmap of 2020. That's why I gave it a try. I didn't expect it to work at all.
The last time (a long time ago) I try that, nothing moved on the mirrored side. But this time, the mirrored side moved down instead of Up.
I was confused when I saw that, and that's I was asking if the "3D sketch mirror" has been implemented!

So I'm guessing, that is just a glitch in the system 😉

Thanks.
Cheers / Ben.

It is my opinion that the observed behavior is as I would expect.

After all, you mirrored around a LINE, not a plane. Points should remain opposite each other around that line. And they should do so without violating the symmetry constraint. One side goes up...its mirror should go down. Makes perfect sense.

It only SEEMS wrong if your brain is imagining how the result should be if you had mirrored across a plane.

good point, @chrisplyler - hadn't thought about it that literally.  But, you are absolutely right.

Man, my wife could learn a thing or two from you Jeff!
