GrabCAD
Sunrise pyramid extruded abstract art shape with ample and complex negative space. Each face is actually an isosceles triangle because it's the result of a boolean intersection of an extrusion with a profile in the shape of an equilateral triangle with an identical copy of itself, rotated 90 degrees around its median vertical axis. Which makes each face of the pyramid a vertically elongated isosceles triangle due to resulting from the projection of an equilateral triangle unto a surface slanted inward 30 degrees.
