Puzzle... how to stand a cube on its corner?

Recommended Posts

So I'm trying to figure out how to stand a cube on its corner so that the opposite corner is directly above it.

I realize I can build some custom planes, I think, based on possibly building a "jig" out of custom geometry...

But is there a "standard" way this might be done?

Fun one...

Plan view, rotate cube 45degrees, side view snap center of rotation to low left corner point, rotate upper right corner to vertical using automatically created guide.

Hi setz - 

Thanks for the note... just getting back to this.

What I've found is that the upward rotation angle after rotating the cube 45 degrees on the z axis is 54.74 degrees on the y axis.

Now, I don't know how mathematically accurate this is (e.g. if used for machining) but it's pretty close!

That should be correct.

You can test a section at half height: the resulting hexagon then has equal length segments.

(For a built example house google  "Piet Blom cube house")

Thanks - and I've seen the Piet Blom houses! (Well, pictures.) I imagine it must feel very interesting to walk through that space.

There really is so much interesting architecture around... and so many new homes still emulate the 1700s...

another way to check:

draw the (3D) diagonale through the cube, group with the cube and rotate like Setz told you.

now you can check the diagonale standing exactly vertical.
