I know it says you cant but.......

I have a large house that I want to change all the window lites from standard mullion to Prairie mullion but window lites it is not a dynamic default. Any suggestions to save time? and wouldnt it be great if there was a way to make any attribute a dynamic default?

Instead of changing in defaults, group select windows, open DBX, and I think you can change all in one fell swoop this way.

I don't think dshall's suggestion will work. (I've tried.) But you can change one window, then select it and use the select similar/load for "lites type," etc. That's pretty fast.

Ah, Richard that sounds cool. Before asking this question, I just searched every icon and menu I thought exists in CA and I would very much appreciate if you could tell me what "similar/load" means and how it works? Is that a function or tool? I can't seem to find it.

Select an object then select "select similar" .

Thanks William. Ill play around with that...curious on the "load" aspect too.
