### Transform Coordinates

**Transform Coordinates** applies a specified
rotation and translation to a model.

There are several ways to start
**Transform Coordinates**, a tool in the **Movement** category.

The **Model** should be chosen from the list of open models.
Its transformation is specified with:

**Euler angles [φ θ ψ]** - rotations
defined by the χ-convention,
where the first rotation is by an angle φ about the Z-axis,
the second is by an angle θ (potentially ranging from 0 to π)
about the new X-axis, and the third is by an angle ψ
about the new Z-axis.

**Shift [***X Y Z*] - translations along X, Y, and Z

For a molecule model (atomic structure or
marker set):
**Move atoms instead of coordinate axes** -
whether to change the atomic coordinates of the model rather than its
transformation matrix

Clicking **Apply** performs the rotation and translation.
The cumulative change from the original transformation
is reported in the dialog.
**Reset** restores the original transformation.
**Set** is equivalent to clicking **Reset** and then **Apply**.
Cumulative change information and original coordinates
are not retained in saved
sessions.
