Hi, I'm pretty new to revit (Revit LT 2020) and have encountered a problem. I'm creating a detail that needs purlin (Z and C) detail components, I download the components from a source online but i get the following error every time I try to load the family - "Invalid column unit type" followed by "Could not parse column header". What's going on here? Is a syntax issue with the text file that came with the family? How can I trouble shoot this?
