Hello, I have what I hope is a basic question.

I am running Caesar 5.20, and as part of my initial input, I would like to apply properties to multiple elements in the model. (I'm not referring to the 'sticky properties', such as material or fluid weight, which propogate automatically)

Say I have 30 elements in my model, and I want to apply a +Y restraint to elements 3-15. How do I do that?
