Which family file is pointing to these? Suppose one needs to add pieces to our/their library.
All of the families called by the VisionREZ roof/trim tools are located in the System Family Master Template File designated in the Revit/Options/ITW tab:
Keep in mind; if one re-installs VisionREZ, the default .rte file will be overwritten. Therefore, if they plan to amend the current list of families, I would suggest you copy and rename the default .rte file (in a different user folder). Then update the “System Family Master Template File Path” in the Revit/Options/ITW to reflect the new location of their .rte file.
This system file only contains all the families necessary for the Architecture/Option tools; the structure tools pull their content from another location: C:\Program Files\ITW\ITW Revit Extensions 2019\RevitContent\Revit Required\Families\Structural Framing. Same principal above applies; if a user amends the list, or changes any of the families, they will be overwritten if VisionREZ is reinstalled. We highly suggest keeping a backup, since we have no control over where the structure tools pull their families from.
