|

<p>Command for modifying <b>Placement</b>.
|
||
These options relate only to the position and orientation of the object in space, they do not affect other attributes of the shape. The placement is stored internally as a position, and a rotation (rotation axis and angle transformed into a quaternion <a rel="nofollow" class="external autonumber" href="https://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation">[1]</a>). While there are several methods to specify a rotation, for instance with a rotation center, this is only used to affect the rotation computation and is not stored for later operations. Similarly, if a rotation axis of (1,1,1) is specified, it may be normalized when stored in the quaternion and appear as (0.58, 0.58, 0.58) when browsing the object later.

|
||
<p>To adjust our <b>rotation parameters</b> we have two methods available.
|
||
</p>
|
||
<ul><li> First option. Select <b> Rotation axis with angle </b><a href="https://www.freecadweb.org/wiki/index.php?title=File:Tache_Placement_fr_05.png" class="image" title="Tache_Placement Option rotation axis and angle"><img alt="Tache_Placement Option rotation axis and angle" src="256px-Tache_Placement_fr_05.png" width="256" height="16" srcset="/wiki/images/thumb/d/d2/Tache_Placement_fr_05.png/384px-Tache_Placement_fr_05.png 1.5x, /wiki/images/d/d2/Tache_Placement_fr_05.png 2x" /></a> (Default).
|
||
<ul><li> <span style="background: #eec8aa; border: 1px solid #bbbbbb; padding: 0px 5px 1px 5px;"><small>TASKS</small> <b> Axis: X</b></span>: The rotation will be on the <b>X</b> axis.</li>
|
||
<li> <span style="background: #eec8aa; border: 1px solid #bbbbbb; padding: 0px 5px 1px 5px;"><small>TASKS</small> <b> Axis: Y</b></span>: The rotation will be on the <b>Y</b> axis.</li>
|
||
<li> <span style="background: #eec8aa; border: 1px solid #bbbbbb; padding: 0px 5px 1px 5px;"><small>TASKS</small> <b> Axis: Z</b></span>: The rotation will be on the <b>Z</b> axis. (Default axis).</li>
|
||
<li> <span style="background: #eec8aa; border: 1px solid #bbbbbb; padding: 0px 5px 1px 5px;"><small>TASKS</small> <b> Angle:</b></span> Angle of rotation in degrees from <b>-360.00 °</b> to <b>360.00 °</b>. (Default: <b>0.00°</b>).</li></ul></li></ul>
|
||
<ul><li> Second option. Select <b>Euler Angles</b> <a href="https://www.freecadweb.org/wiki/index.php?title=File:Tache_Placement_fr_04.png" class="image" title="Tache_Placement Option Euler angles"><img alt="Tache_Placement Option Euler angles" src="256px-Tache_Placement_fr_04.png" width="256" height="37" srcset="/wiki/images/thumb/4/48/Tache_Placement_fr_04.png/384px-Tache_Placement_fr_04.png 1.5x, /wiki/images/4/48/Tache_Placement_fr_04.png 2x" /></a>.</li></ul>
|
||
<p>This option may be easier to work with, however, even in this mode, there are important things to remember:
|
||
Positive rotations are in the <b>clockwise</b> direction, looking <b>out</b> from the origin along a positive axis. Or to put it differently, the rotations are positive in the <b>counterclockwise</b> direction, looking <b>in</b> to the origin along a positive axis.

<p>Yaw, pitch and roll refer to the <b>attitude</b> of an object in 3D space. These terms are commonly used in aviation.

The angles are the <b>Tait-Bryan angles.</b> If you want more information, try <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Euler_angles">Euler angles</a>.
