Y wall joins are not automatically created when you use the Auto join walls preference. (See Vectorworks Preferences: Edit Tab for information on Auto join walls.) Instead, use the T Join mode to create Y wall joins.
To create a Y wall join of three wall segments:
Click the Wall Join tool from the appropriate tool set:
● Fundamentals workspace: Walls tool set
● Design Series workspaces: Building Shell tool set
● Landmark workspace: Site Planning tool set
Alternatively, right-click on the first wall to join and select Join from the context menu.
Click T Join from the Tool bar.
Select the wall segment that must change length to abut the two previously joined wall segments.
Select one of the two wall segments to join.
The wall segments are joined.
