Hello Karsten
first of all friend
I hope you had a Marry Christmas....

Some clarifications on Vectors, recently implemented ,
I think it is necessary that we should have in the output vector
a choice :
1- End point of the vector calculated in combine with the base point
2-Curve
3-Vector-visible and not

That would save a lot of redundant mathematical calculations
to define curve and they point applications

Also , it would be nice, to have a node for
Rotate Vector...
input
- Base point of rotation
- Vector reference
- Radians or Degrees _ ( ) / [ ]
Output
like above

I started testing today the Vectors
and at the moment these are the observations
the most important that I wanted to notify you
I can not send files and images,in the traditional way ,
so I refer you to the following link

have a nice day
