VectorUnit_i
The VectorUnit_i function takes no parameters. It returns the i-unit vector, e.g., (1,0,0). The vector to which the unit vector is assigned must have previously been defined with the $Vector or $Vector2D directive.
VectorUnit_i may be followed by multiplication/division with a scalar or addition/subtraction of a vector.
Example:
$Vector X Y
X=VectorUnit_i*(3 [kN])
{Solution:
x = (3, 0, 0) [kN]
}
