this:
normal_vector = normal_vector + face.normal

will not work as expected, if you set normal_vector to reference the integer object 0, because the integer +() method will get called, and it is not likely that it would know how to handle an argument that references a Geom::Vector3d object.

Smarter to create either a unit vector object to start with, or a zero length vector:
normal_vector = Geom::Vector3d.new(0,0,0)

THEN, when you call the +() method using:
normal_vector = normal_vector + face.normal
the special vector addition API method will get called.

In other words your statement is evaluated as if it were written:
normal_vector.=( normal_vector.+( face.normal ) )

This is one of the important things about Ruby... = and + (etc,) are not really operators, they are instance method names.

Hello,

I think I found where the problem lies:

After testing many variations to my formulas, without success, I had the idea of changing the internal units of the component.
Being Belgian, I naturally use metric units, so my component was configured with "cm".

So I converted all numeric values in inches and reconfigured the component to use same unit.

Miraculously, everything works now as expected 😍 , even when using the component in a model configured in metric units.

I think there's a bug in the function CURRENT("LenX/Y/Z") which should return a value expressed in inches, whatever the choice of internal units.

Well, I hope my experience will serve the other!

Thank you for your attention,

Gerard
