Im pretty sure if you check your list of analysis grid, you have a null value somewhere so the Curve.Length node is outputting an error.

i’ve checked manually and also checked with “list.clean” script, and i didnt found any null data

can you provide the script and a sample revit file?

Hi @farhanardianzaf
filter out the value that cause the problem or use list.map.

Hi @paris, i am new to this thing, and i don’t know what you mean. Can you please explain to me

Try using an Object.Type node after your codeblock for the analysis grid and then a List.UniqueItems, and preview the results. If any of those object types don’t have a valid length.

Hi @farhanardianzaf can you show the error of your node “Curve.Length” and the image of your graph? check also the output of “Curve.Length” node like this:
