Truncated Cube

Does anyone have any advice on creating an accurate ‘truncated cube’?
(Note that all edges in this model are identical length)

I’ve tried creating an 8-sided circle as a starting point, and rotating it 22.5 degrees. This gives me one face, but can’t get the edges to correctly snap to the grid so that I can accurately create the other faces.

Is there maybe a way to create this starting with a cube?

add a cube
modifiers > bevel
check “only vertices” and set the bevel width to .5
you can then apply to make it real.

happy blending!

:edit - my bad, width at .586 is giving me the best results for uniform edge length.

I would of suggested a Boolean, but that should work too. :slight_smile:

You don’t want to snap to the grid, you want rotated copies of your first face to snap to vertices of each other.

Is there maybe a way to create this starting with a cube?

There would be, but I think starting with an octagon is probably easier.

Best wishes,

This is not the most accurate method. But you can just subdivide the cube in 3, erase the corners, than reface it.


Thanks Matthew, I have now successfully created this model, (after figuring out how to snap vertices to each other…)

Thankyou too for the other replies, though I think Matthew’s is the most accurate with uniform edge lengths, The other methods are useful for variations on this shape!

My first blender mesh! Awesome.
