Hi,
The node that is initialized first will appear first in the program.

If you have 5 nodes and you want to add a node 2,1 between node 2nd and 3th you need to initialize node 2.1 . Then duplicate node 3th, 4th and 5th, after that delete old node 3 4 5.

In ALLPLAN 2025, users can change the order of node inside the palette designer to affect which node should run first. The node on the top of the list will run first.

In other old ALLPLAN versions, users don't have this possibility to affect the order.
