Do you mean words like "casing", "sill", "stool", etc. in the parameters or something else? Most of these are standard architectural terms although they use "frame" where "jamb" would be more accurate and use width and thickness in a confusing way. It is true that library parts are not sufficiently documented. This is part of what I do for my clients but I haven't yet found a way to expand my efforts to the world at large (short of my occasional posts here).
