how to find the bounding box of a 3D object

[gbettega]

Hi,

once I've loaded in a 3D picture control my 3D CAD model (for example in .stl format), I would like to found the dimension of the bounding box.

Any idea about that?

Thanks in advance

D'you want the bounding box in x,y and z? If so, you can use a property node on the mesh refnum to grab the mesh vertex array. From this you just need to look for the maximum and minimum in each dimension.

I've attached a VI for reference (which also adds the bounding box to the scene).

Edit: There was a mistake in the VI I uploaded.

This is the solution I was searching for
