- - - - scroll up/down to zoom in/out
    - - click and hold scrollbar and drag mouse left/ right to pan
    - - press ' shift' key + click and hold scrollbar and drag mouse to orbit.
- - - - insert projected views
        
        insert projected views and isometric views. so there should be three views and a fourth 3D isometric view on drawing.
    - - save an empty version
        
        save an empty version as proof of your own work
    - - add in dimensions and view labels
        
        all dimensions should only be indicated once
    - - drawing> from design
        
        switch to drawing work, to create a drawing from an existing design.
    - - insert the base view
        
        insert the base view, which is the front view, use a suitable scale, so when more information is added into the drawing later, the drawings will take up a good amount of space without looking cluttered.
  - - - save an empty version
    - - create sketch
    - - use "line" to draw 2D profile
    - - sketch dimension and specify dimension of each line
    - - extrude the 2D profile
    - - save completed work
- - - - are constructed on 3 axes that divide the circle equally. they are 120 degree from each other.
  - - - in the image the three axes shown( in blue, red and green) are 120 degree apart.
        in isometric drawing, the vertical lines will also stay vertical.
