This question of mine may also apply to the Grasshopper itself, not only a Karamba plugin.

 

What I have been puzzled with, for some time, is how to define a vector, when I need an input of vector, like in this case with Karamba plugin?

 

Is this the solution:

?

 

Using unit vector, multiplied?

I'm not familiar with Karamba but you've certainly provided a vector input.  Other ways to define a vector are in the vector menu.

When you define the Z unit, you need to remember that -Z is the direction of force in most models. So if you want to apply a 100kN load downwards, -100 Z Vector would be required.

Thank you for helpful answers, both of you.

 

I found two more solution to define a vector:

are there more?

You can create a vector from two points and there are some other components that give vector output (ie. normal vectors and tangent vectors).

Thank you Chris.

 

One more question:

Why I can not see the vectors in the last two methods, I posted above?

I can only see the ending point. Why is there no line between the ending point and the beginning of the coordinate system (0,0,0) ?

Hi Najna, use Vector Display component (vector > vector > Vector Display)
