Impossible Cubes

[gwpriester]

My cube examples were very quick and crude.

I'm an artist not a mathematician. And I have made hundreds of cubes for my stereograms.

My method is more primitive but it works for me.

I use the QuickShapes Tool to make a hexagon using the Radius Creation Option.

I zoom in and snap two guidelines to the center of the cube.

I use the Shape Tool to draw the top shape.

Rotate and duplicate the top shape around the bottom point 120 degrees. Then once more.

It works for me.
