This a minor annoyance. When I'm working on the construction drawings I occasionally have to make a minor change to a window or door. Maybe add an egress check to it. Maybe add a comment that it needs to be tempered glass, etc.. Everytime I do this it erased the door/window schedule Manufacturer and Model Code number. Is there a way to prevent this? It should really only erase/reset this info if your changing the height and width of the window. The rest of these changes are options that should affect the manufacturer and model number. Maybe a lock option?
