Thanks for the info. I had started with the Default style. I found the 'Today's Traditional' has the casings I am looking for. Am I right in assuming I need to cut and paste each of the door and window types I need from the Traditional plan to my plan and replace my existing doors and windows? (i.e., no way simply copy the 'default' casing to my original plan and have it applied to all existing doors and windows).
It would be great if casings were as easy to modify as moldings though '-)
Thanks for the tip on updating my sig. Done.
