Hello everyone,

in this script i'm trying to pick a detail item family.

if the text_parameter name of the detail item is p.Definition.Name == comments_structural_framing i need to find the type name of the corresponding structural framing family. i then need to write this type name to the value of the text parameter in the detail item family.

apparently is not finding any p.Definition.Name == comments_structural_framing so it skip to "Parameter not found or has invalid type".

I know it's a little crazy but i hope you can help!

thanks

"i need to find the type name of the corresponding structural framing family"

if i understand well, you want to find the type in the class OST_StructuralFraming with the corresponding name of a detail family?

Yes. Where the parameters name of the detail family are equal to the comments parameters of the structural framing family.

i suggest to create a dictionary.

get your detail element names.

then create a dictionary of your OST_StructuralFraming, comments : name of type

then create loop on your detail item's name and search in the dictionary.

hope that might help.
