Dear xenofex22,

By working in engineering tool, you can define any reinforcement you need. You can use a formwork model to define your stirrup and bars. Because the object are not combined together, there is no direct link with the architectural element and the renforcement. So if edit the columns, there will be no change on the reinforcement. But you can easily stretch your formwork and bars if you need.

In an other way, you can also use a smart part. In the case of the smart part, it's different because it's one object which combine sube object (volume + reinforcement). In this case, the handle can change all.

The smartpart and python are quite new and it can be interresting to use in some case. But in fact, we mainly use the first method.

Bye & Good Use!
