I wonder how i can make Twisted Cube in ARCHICAD?

Try OBJECTiVE, an add-on for ArchiCAD. It allows you to make profiled shapes that can be twisted along their length. Referring to the attached image:

• 1. You could use the bundled Regular Profile object. Set it to 4 edges, fill in the bounding dimensions, and enter an angle to twist the shape through.
  2. The finished shape in 3D (to the right)

Note that for a cube shape, GDL starts to break down a bit if you twist it through more than about 15 degrees. If you require more twisting, you can make a profiled shape with each edge divided into multiple segments with OBJECTiVE > Component > New Profile. A shape made this way is shown to the right (twisted through 45 degrees).
