I want to create my own .ddy file


I’m looking for materials because I want to deepen my understanding of “design day”.
Does anyone know more about “sizing” or “design day”?
I’m looking for it.

Thank you.

The 0::Import tab of the LBT Ladybug plugin has a number of components allow you to import design days from DDY files and then deconstruct or import those design days to get the conditions over the course of that day.

LBT Dragonfly also has a couple of advanced components that allow you to construct your own design days from parameters and write design days into a .ddy file.
