Solved How can I get the edges of cube?

I made a cube of 2 extreme points and I have a question how to get these edges of this cube?

 

Differentiate with each coordinate of the other extreme, one at a time.

Code:

# A and B are two extremes
# x1 <= x2, y1 <= y2, z1 <= z2

A = Vector3(x1, y1, z1)
B = Vector3(x2, y2, z2)

# Edges:
From A to A->add(x2, 0, 0),
From A to A->add(0, y2, 0),
From A to A->add(0, 0, z2),
From B->subtract(x1, 0, 0) to B,
From B->subtract(0, y1, 0) to B,
From B->subtract(0, 0, z1) to B
