# Auto align

<img src="/files/UtSj79cVEEcj7SZgqYzK" alt="" height="50" width="50">

Automatically align selected rooms to common axes identified across them. The command is intended to automatically perform most of the alignments that would typically be done manually. Note that having a line selected while running this command will force the generated alignment axes to be generated only in the plane of that line.

## Options

* **Distance**

  The distance with which room vertices will be aligned to common axes. No vertex in the input rooms will be moved more than this distance
* **Exclude Angle**

  A positive number in degrees for the maximum difference that a geometry segment can differ from the alignment axes for it to be ignored/excluded from alignment
* **Base Story Name**

  Optional text for the name of the level among the selected rooms to be used as a base for auto-aligning the other rooms in the selection. Rooms on this base story will not be edited during the alignment operation.
* **Axes Only**

  Select to have this command only output the common axes of the selected rooms into the scene and not perform any auto-alignment of rooms with these axes. This can give more control over which axes are or are not used by allowing manual selection and aligning with desired axes
* **Use Anchor Lines**

  Select to have the currently selected line geometry override any suggested alignment axes. This can be used to ensure that auto-aligning does not move parts of the model that are already correct.
* **Group by Base Plane**

  Select to have the command group the selected rooms by the underlying base plane that best fits the room geometry before auto-aligning them. This is useful in cases where the selected rooms contain different structural grids that are at angles to one another.
