Box/Bounding Box larger than it should?

[halodri]

Hello,

I want to bound an object with a box; however, the box is much taller than the object. Is it just me being a newbie, or is something else going on? I have tried box and bounding box, same result.

If someone has a tip or dares to take a look at my spaghetti, I would appreciate it!

Your attached .3dm file contains nothing.
… and you didn’t attach any .gh file.

Ups, I apologize.

Yep, something is wrong.
As workaround, for now you can do this:

---

@wim this seems a bug.
Rhino 7 or Rhino 8 , same result.
Grasshopper BoundingBox component OR Rhinocommon .GetBoundingBox(true) result in this:

.GetBoundingBox(false) is less wrong … but also less accurate.

Rhino command instead return a good bounding box …

In the loft options, enable Align sections and the Bounding Box of the loft is correct.

Thanks all.
I’ve added this sample to RH-69696 Grasshopper: BoundingBox is larger than expected
