How to keep list structure

[vanman]

How do i keep the list with the emptys going through? Need them down the track to line up with other stuff. Need it to retain as a list of 19 after going through this node

I dono… Do i need to get the list structure and map it or somthing back in at the right places?

Not at work but ended up replacing the nulls with one of the curtain inputs to keep the structure the same through the gridline node

[vanman]

had to replace empty’s with nulls then replace nulls with curtain grids

Something is still going wrong in my list structure to get my script to dimension correctly. However found this python code that solves all that mess above.

If empty continue

It’s just kind of a dumb thing that Dynamo has trouble with. Your best bet is to use a simple Python script to do it for you. list = IN[0] replace = IN[1] out = [] for l in list: if l == []: out.append(replace) else: out.append(l) OUT = out

Not sure what this error is though and its still not quite right after going through the Element.CurtainGridline
