i created this script because i have a blender file that’s have alot of cubes with unneeded faces the most of them have 10 faces so i maked this script to replace this cubes with another normal cubes from add mesh menu that only have 6 faces by getting the old cube locations and dimensions and rotation then saving them to text files then delete the old cube then setting a the old cube data to the new one
the script working very good when i replace normal cube with another from add mesh menu but when i test this with the cube that have 10 faces i get a bigger cube and little different rotation and location but i have the right data in the transform menu
my code
import bpy
import re
file_data = [] # create an empty list
animation_data = {} # create an empty dictionary

there are two big cubes on my blend file the blue cube are the cube with ten faces and the red cube just a normal cube i added from mesh menu and created the small cubes around them are just to make you notice the dimensions for the cube that created after running the script with the cube that have 10 faces but if you runned the script with the red cube the cube replacing will work perfect and the new cube will take the right dimensions succesfullyproblemblend.zip (155 KB)
