    fix boolean operations

Sometimes boolean difference fails. Before try on each object:

• edit mode
• select all vertices A
• vertex (top menu) → Merge Vertices → by distance (this operation remove duplicate vertices)

• select (multiple) object and SHIFT+H to hide others
• recall others with ALT+H

TAB key

• activate Vertex select with 1, Edge select with 2 and Face select with 3

Create new object from selected vertex:

• duplicate with SHIFT+d
• ESC to exit from grab mode
• parent selected with “p”
• exit from edit mode with TAB and you will have two objects

CTRL+l: select touching vertex, edges, faces

Recalculate normals (to solve bevel problems): select all with “a” and hit “shift+n”

knife mode K:

• c for angle constrain
• z for cut all deeper edges

put vertex same X, Y or Z:

• position the 3d cursor at the Y location
• set the pivot point to the 3d cursor (. period key)
• then scale by zero on the Y axis (S Y 0)
