Decks, Landings, Walls
Extensions where a Deck and a Wall meet or where a Landing and a Wall meet will remain associated with the Deck or Landing and not jump to the Wall.
Overlapping Extensions
Mask Overlapping Extensions option added creating a gap in one extension where two extensions cross.
Small Items
Placing and editing Dimensions and Extensions on very small objects improved. Extensions could disassociate upon a Dimension edit in older versions.
