不懂grip，不过看上去是沿着xyz轴求的外形尺寸，如果是这样的话，这个用open nx好像一个函数就可以了
/******************************************************************************
Returns the bounding box information of wireframe and solid type objects
aligned to a CSYS.
Wireframe objects include lines, arcs, splines, and conics. Solid type
objects include bodies, faces, and edges. Bounding box values are
returned in absolute coordinate values according to where the object
exists in the part file and aligned to the input CSYS.
If you call this function with an occurrence, the bounding box
of the underlying geometry is transformed into assembly space.
Use occurrence object tags when working in an assembly context and prototype
object tags when working in non-assembly situations. Passing in a prototype
object tag when in an assembly may produce undesired results.
The csys_tag should always be in the context of the current work part.
To derive the corner points, use the X,Y,X components of the
min_corner and then add the X,Y,Z components of the directions multiplied
by the X,Y,Z distances. For Example, to derive the 2 corner points:
corner_pts[2][3]
While a more accurate box is produced, processing time may be increased
significantly.

恩，是的
最小包围盒是个几何难题
目前较多的做法是采用三角网格模型来计算。
