Please help me to fix and improve the code.
On the sketchucation forum I found the code Help please. How to get transformation for the face • sketchUcation • 1
With the help of AI, I was able to refine it a bit for my needs. I added display information about the name of the object and its dimensions. But then I encountered the problem of incorrect display of object sizes if they are rotated relative to the global axes (shown on the screen). Please help me correct the actual size calculation.
The second thing I would like to fix is the selection of the whole object (group/component) instead of just the faces.
Here is the code:
