Hi Everyone,
I have a Duct Fitting family which gives me quite an interesting error when I try to load it into a project.
The error states the following:
"An error occurred in family "xx" that cannot be automatically resolved. Error information: Last type in System family "stacked wall" cannot be deleted
The family is a duct fitting (eccentric transition) which I load into an OOTB mechanical project. I am pretty sure my client downloaded the family and modified it, but I cannot understand where the error lies.
I have deleted dimension parameters, deleted formulas, deleted geometry, nested the family into a new duct fitting family, changed the category, but no luck yet. I am busy re-creating the family to save time spent on reverse-engineering the family, but I am very interested in hearing if anyone has experienced this error before and/or found a solution?
I have attached a few images (The family can be provided if requested)
