How to turn any mesh into its bounding box

I have a scene and I want to turn it into a blockout scene for presentational purposes. I want to turn every mesh into a box or a block model. Is there any way to achieve this? Scripts are also welcome

Bmesh script

Quick, n dirty little bmesh script to do this. For all mesh objects in the screen replace the mesh with the box created from the eight corners of the bounding box.

script

import bpy
import bmesh
context = bpy.context
scene = context.scene
bm = bmesh.new()
mesh_obs = [o for o in scene.objects if o.type == 'MESH']
for ob in mesh_obs:
me = ob.data
#me = ob.data.copy() # create a copy

verts = [bm.verts.new(b) for b in ob.bound_box]
bmesh.ops.convex_hull(bm, input=verts)
bm.to_mesh(me)
ob.data = me # needed if copy
bm.clear()
bm.free()


You can select Bounding box in Viewport Shading setting:

This option displays all objects as it's Bounding boxes
