====== Blender 2.9 ======

====== shortcuts ======

  * SHIFT z: switch wireframe and object mode
  * f: fill faces or edges between edges or vertex
  * a: select all
  * ALT+a: select nothing
  * c: circle select
  * b: box select
  * SHIFT+b: zoom to box
  * SHIFT+s: cursor move or selection move
  * w: cycle between selecion modes
  * 
====== numpad emulation ======

  * edit -> preferences -> input -> emulate numpa
  * enable 1,2,3 switch faces,edges,vertex: edit -> preferences -> keymap -> search mode
    *  select mode toggle: ALT+1
    *  select mode toggle: ALT+2
    *  select mode toggle: ALT+3
===== 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)
 

===== hide / show =====

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


===== edit mode =====

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)
