Hi,

Here is an example of the loop while being used, hopefully it helps you understand it…

Basically I made a custom node for the generation part. inside are: geometry generation, BIM elements generation, export and archive, erase all BIM elements. Inside the custom node the sequence of theese actions are managed by passthrough nodes (but you can do it in other ways)

Cheers,

Mark
