All of the families in the SD ToolKit are intentionally designed to represent generic version of common building products. During schematic design, I’m rarely concerned with the exact specification or model of any singular item. IE the first time I’m proposing a pocketing glass door system, I’m not concerned yet whether it’s from Western, Fleetwood, or Sky-Frame. Those are discussions for the Design Development phase.
My families are intended to quickly cover what Architects care about during the early phases of design. We need to account for widths, heights, clearances, etc. in plan views and immediatley have a good looking 3D representation for renderings.
Generally speaking, I’ve found the Revit families developed from most manufacturers are built to be more of a sales tool than be a useful tool for schematic design; They are overly constrained with parameters we don’t care about or they provide us with 30 different models with minor variations that are difficult to swap out. Neither of these approaches are useful in SD when the goal is rapid iteration.
