ProximityDetection_WallJoinControl
§Four functionalities:
§1) find columns in walls, 2) find elements blocking door ways, 3) find walls at the end of walls, and 4) check walls join/disjoin states.
§Main classes and methods:
§ElementIntersectsElementFilter, ElementIntersectsSolidFilter, GeometryCreationUtilities.CreateExtrusionGeometry(), WallUtils.IsWallJoinAllowedAtEnd(),
WallUtils.(Dis)allowWallJoinAtEnd(),
LocationCurve.ElementsAtJoin(),

This sample demonstrates how to: find columns in wall, find elements blocking egress, find walls (nearly) joined to end of walls and check walls join/disjoin states using the ElementIntersectsSolidFilter, ElementIntersectsElementFilter and WallUtils classes.
