By default, Revit locates the boundary lines in the middle of the walls for both interior and exterior walls. You can use a combination of [Create Boundary](/user-manual/model-editor/commands.md#create-boundary), [Offset](/user-manual/model-editor/commands.md#offset), and [Align](/user-manual/model-editor/commands.md#align) commands to adjust the floor boundary to match the outside of the exterior walls. {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook.
