I have done some work on some of this ... especially related to lines and=

'curly arrows'.

Concerns I have ...

Q: How does one specify XYZ coordinates?

Q: Are they just 3 numbers, or do we use some type of encapsulating
syntax? ... as in =5Bx,y,z=5D

Q: What is the relationship between a drawn object and models/frames? Can=

an object exist in more than one frame?
