Hi to all…
I’m trying to create an Excel complex export to use data for Facility management. I’m starting from the HVAC information.
The question is: how I can drive the flow of the script based on IF statement? I receive an error if the list of object is empty (example: in the project there isn’t an Air terminal and so on).
This is a WIP so stay tuned because I will have a lot of questions 
You can use List.IsEmpty as a condition:
I mean something like: if yes do this and if false do this, like a flow chart. Is this possible?
like an IF…THEN…ELSE statement, that would be welcome
Theoretically, you could do that in a Python node, but I have not yet tried calling any Dynamo functions other than Geometry functions, so I can’t say for sure if it would work.
Ok…
another question. I’ve tryed to query information on elements and I’ve received the ID of the family type…perfect
But, when I want to link the ID to a Name, I receive a blank list…I’ve this problem on several element or categories
Any idea…with this informations,a VLOOKUP and some pivot in Excel I can link and name to id like in this case
LoL. I haven’t seen it…thanks
Having Revit DBLink installed (as i see in the picture) gets you all the data.
An overview of all categories with all OOTB parameters, editable/not editable, that would be nice
yes I know but…I want to export and import data using dynamo to put exactly what I want where I want…
Any idea on the IF THEN ELSE node?
