here is a model to check if you want to start trial of "REACH TARGET" loop function

3dxml below

the model is to create a rectangle of 1.5m2 by tuning its height between 100mm and 300mm... I think super basic for everyone in the community.

the purpose is that you can refer to a visual script for more complex use case.

I also added @TV ​​​​​​​video for bottle volume use case (more complex). Thanks RD!
