I have zero knowledge of Allplan's visual scripting, but I have some knowledge regarding programming and visual scripting in other software. The initial questions are:
- Is it easy enough to create a visual script tree which does the job of the title?
- Is it easy enough as someone doing it and post a screenshot?

The workflow I guess I need is to
1. Select all objects.
2. Filter them by type (I need all Reinforcing Bar objects).
3. Get the value of the Formula-typed attribute (of ID X).
4. Copy the value to the Entry-typed attribute (of ID Y).

I tried to see how I do with selecting objects and filter them, but I couldn't find my way around. I have not yet started to research online a lot, until I get some starters guidance (from here).
