[DARARepeater] 3D Modeling Class Tomorrow

Fri Sep 20 18:42:55 EDT 2024

Logan,
What you presented is a "command line" interface like we used in DOS 
command line statements back in the '70s-'early'80s....LoL?
Well, if one just wants to make cubes, on-top-of-cubes, in 3D this is 
what you want...LoL!
