Skewed parallelepiped

[alenyoungyo]

How do you construct a parallelepiped that has all sides equal and the angles at one of the vertices are acute and equal?

@alenyoungyo I made this one with 12 equal triangles constrained together at their vertex's

Hi! On top of what experts already mentioned, you may create two spheres (one at the lower left and one at the upper right). Then trim the surfaces using the spheres. You will get the desirable edges to select for creating the frame members.

Many thanks!

Thank you, but how do I implement step 2 (drawing an angled line to a plane)?

Thank you, but the angle in the XZ plane will be equal to cos(x)/cos(x/2).
