In both Home Designer Pro 2016 and 2017 the Lock options (as shown in Help and KB articles) are missing from the Arc Specification Dialog. This makes it almost impossible to create site plans with accurate arcs.
I've included a screenshot from the Help and KB articles that show the missing Lock option in item #1 of the image. I am also providing the links to the Help and KB articles below.
I specifically need to use the "Lock Chord" option. Is there a workaround solution for this?
