If the OP really does not have any involvement with Visuino then his question seems perfectly reasonable.
I have never used it so I can't help.
I am always a bit wary about things like Visuino that shield you from the nuts and bolts because you will be be very badly stuck if you get deep into a project and then find that it can't do something because the developers never bothered to provide for some special case - or if the documentation fails to explain something clearly.
