This author in the video has used FreeCAD Version 0.14, and hence some of
the operations demonstrated in this video are no longer valid in FreeCAD
Version 0.18. I will try to release a detailed procedure I have taken to
create this model soon....
Key dimensions for the various shapes used in Part Workbench are,
Cube 36 x 36 x 36 mm
Sphere Radius = 25
Center the cube to the origin.(Transition X, Y and Z by -18 mm)
Select both the cube and the sphere and use the boolean operation Intersect.
Draw 1 to 6-dots on each face of the dice.
Select a face and draw a square 16 x 16 mm
Draw circles of Radius = 3 mm on each face to create 1 to 6 dots.
