Hi Chin,

I suggest opening example scripts and images, trying to figure out how the examples work, then replicating the methods on the sample images.  Vision Assistant is built to be a simple method for writing complex LabVIEW code, so it will be a great place for you to start.  Also, try searching the forums for example scripts, and see how other users write their code. 

Good luck!
