I have been using Chief Architect's Home Designer Pro for about 5 years. I currently have the 2017 version. I am designing a deck that is 10' off of the ground. i want to put in my drawing a 45 degree angled brace about 3' long at the top of the post to help prevent any racking or sway of the deck. I can't figure how to make the angled brace with my software. Anyone know how this is done?
