Vision Builder - draw line from global variables

[noxus]

Hello,

I've started using the Vision Builder for Automated Inspection program to develop some really small apps.

Now I'm creating a larger application and I want to draw some lines, ... based on some values located inside my global variables.

When I select Custom Overlay and Draw Line I can only set to Start and End point to a User-defined value. (so a "constant" value)

I cannot find how I can use a global variable to specifiy the behgin en and point.

Is this because you cannot have points as global variables?

Is there another way (create a LabVIEW VI  that takes some global variables as an input and outputs points) so that I can do what I want?

Thanks in advance for all the help!

You need to define a global variable of type Point (last item in the list).

See attached example.
