More possible code to modify faces

BPY-API

Accessing data from the currently loaded blend file is done with the odule bpy.data
examples

========== step 1 ========
import bpy
print(list(bpy.data.objects))

bpy.data.objects[0] bpy.data.objects[“Cube”] ====================

bpy.context.object #- this gets the last object selected, not necessarily an actively selected obhect

========get the data block- see python tool tip on button==
bpy.ops.mesh.primitive_cube_add(enter_editmode=False, align=’WORLD’, location=(0, 0, 0), scale=(1, 1, 1))

bm-1100-Screencast – my video

Not very useful in my opinion, doesn’t compensate for a bad video. If you can’t follow what is being described, having the keys and mouse displayed is not going to make the video any better.

b-2010-Join-Unjoin

To join objects in object mode you just select all of the objects to be joined and then right-click and select ‘Join’.

To unjoin you must go to Edit Mode (Tab)
Select all vertices using ctrl+A
Select mesh menu->Vertices->Separate->by loose parts or just Press P and choose by Loose Parts
