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of the operations demonstrated in this video are no longer valid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 Parts Workbench
are,
Cube-1 = 90 x 90 x 90 mm
Cube-2 = 80 x 80 x 80 mm
Cylinders, Radius = 27.5, Height = 90 mm
Using Part Design Workbench create a Sketch and draw a triangle using polyline in XZ plane,
Set Hypotenuse = 56 mm, Set right angled corner point to 65 mm from
Z-axis and 50 mm from X-axis.
Rotate the sketch object by 45 to position at the edge of the
cube.
Pad the sketch by 60 mm symmetrical to the plane
Duplicate this body with sketch, 8 times and re-position to cut each
corners of the cube.
