Each box (cube) is defined by coordinates (xi,yi,zi) of one corner and length of 3 sides (ai,bi,ci). I would like to show them on 3D graph like on attached sketch. Any hint would be appreciated. Thank you,

create a series of line segments defining each cube in 3d, then transform them in to a 2d xy plot using geometry. Then plot the resulting xy plot.

That will give you a wireframe, not a hidden line drawing.

Cheers

IV63 - the blog post below has an open source Excel spreadsheet that will do 3D wireframe drawings from a list of coordinates:
