I can't see anything in it about vectors. How is it a vector drawing program?
Sometimes I wonder why I bother....
In my post above :
for the avoidance of confusion, the word vector in my case refers to "vector graphics", i.e. in contrast to "raster graphics", not special wind vector drawing software !
I specifically said a vector was a type of graphic ! And that you should use them because :
you'll then be able to size them as you need them without loosing fidelity
How you draw your wind vectors in them is up to you. But you shouldn't need to use besier curves to do so ! I've never used it...but surely the non Adobe software offers the ability to draw lines !!
Anyhow, good luck to you in your endeavours. I'm done with contributing to this thread.
