Returns the 3D distance between two points
(distance pt1 pt2)
Arguments
A 2D or 3D point list.
A 2D or 3D point list.
Return Values
The distance.
If one or both of the supplied points is a 2D point, then distance ignores the Z coordinates of any 3D points supplied and returns the 2D distance between the points as projected into the current construction plane.
Examples
Command: (distance '(1.0 2.5 3.0) '(7.7 2.5 3.0))

Command: (distance '(1.0 2.0 0.5) '(3.0 4.0 0.5))
