Andre,
Thanks alot!! I fixed the upper sash family but had not reloaded it yet. I know exactly what you are saying with the size of the family, but I do have a method to my madness (maybe I am still wrong
) I welcome your advice if I should do this differently.
My understanding is that when multiple Revit Family have the same families loaded in them that when inserted into a project each family essentially has its own copy (thereby increasing the overall project size and increaseing time for changes to family). For example, door families that are based on different frame types, each family having the same set of door panels loaded.
Based on that theory, I have setup door families (hinged single, double, sliding, pocket) that are separated into different families by frame type, each family has all 18 of our door panels loaded in as shared. And our template has all of these shared door panels loaded in as well. Pre-loading these panel families in the template greatly reduces the loading time of the door family. Each door family has a few sizes with the basic flush panel set for the panel type. I load all the shared panels in so type catalogs (with all panels, sizes, etc) will work. I set the families up this way becuase theoretically all the doors ever loaded should share the same set of panels.
My intent was to do something similar with the windows.
After we tackle this question, I have some ideas on mulled windows, too.
Thanks again
Dave
