How does [Load Near Intersecting] of Section dialog work?

 What is the size of the bounding box of [Load Near Intersecting] in the [View/Edit Section] dialog?

Load Near Intersecting: Return all the components that intersect the plane and are within the given distance of existing visible components on this plane.

Distance is computed as follows:

Find cumulative axis-aligned bounding box of all un-suppressed components in the assembly

Find largest dimension of the box

Tolerance used for loading is = “Largest Dimension of bounding box"/ 20

Here, The Largest Dimension of bounding box is =MAX (deltaX, deltaY, deltaZ) of combined bounding box of all the components.
