Tasks Placement/ko

Description
Command for modifying Placement. 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 ). 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.

Usage
The function Placement can be accessed in several ways:
 * via script Python in the console and its API.
 * [[Image:PlacePyConv10.png|Scripting Placement as y/p/r and Matrix]]


 * or, in the window Combo View → Properties → Data → Placement → ,
 * [[Image: Tache_Placement_fr_01.png|Task_Placement]]


 * or by the menu Edit → Placement....

Enable Placement in Combo View

 * Click a shape to select it.
 * Click Placement (the title, not the little arrow), and a button with an ellipsis appears:  [[Image: Tache_Placement_01_fr_00.png|256px|Tache_Placement]]
 * Click on the ellipsis, and the is displayed:

Options

 * Tache_Placement_Translation_X_fr.gif Moves the coordinate system of the object in the X direction in relation to the axis coordinates of origin 0, 0, 0.
 * Tache_Placement_Translation_Y_fr.gif Moves the coordinate system of the object in the Y direction in relation to the axis coordinates of origin 0, 0, 0.
 * Tache_Placement_Translation_Z_fr.gif Moves the coordinate system of the object in the Z direction in relation to the axis coordinates of origin 0, 0, 0.


 * : Move the center of rotation in the direction X, from the coordinates of the selected object. (default: 0,0,0).
 * : Move the center of rotation in the direction Y, from the coordinates of the selected object. (default: 0,0,0).
 * : Move the center of rotation in the direction Z, from the coordinates of the selected object. (default: 0,0,0).
 * : Allows you to change the three axes ( X, Y, Z) in a single operation [[Image: Part_Revolve_fr_06.png|96px|User Defined]].

To adjust our rotation parameters we have two methods available.


 * First option. Select  Rotation axis with angle [[Image: Tache_Placement_fr_05.png|256px|Tache_Placement Option rotation axis and angle]] (Default).
 * : The rotation will be on the X axis.
 * : The rotation will be on the Y axis.
 * : The rotation will be on the Z axis. (Default axis).
 * Angle of rotation in degrees from -360.00 ° to 360.00 °. (Default: 0.00°).


 * Second option. Select Euler Angles [[Image: Tache_Placement_fr_04.png|256px|Tache_Placement Option Euler angles]].

This option may be easier to work with, however, even in this mode, there are important things to remember: Positive rotations are in the clockwise direction, looking out from the origin along a positive axis. Or to put it differently, the rotations are positive in the counterclockwise direction, looking in to the origin along a positive axis.


 * Yaw : is a horizontal rotation of a body about a vertical axis. (The symbol ψ is often used for yaw.)
 * Pitch : is defined as an oscillating movement of a vessel fore and aft.
 * Roll : is a rotary movement of a body about its longitudinal axis (roll axis).

Yaw, pitch and roll refer to the attitude of an object in 3D space. These terms are commonly used in aviation. The angles are the Tait-Bryan angles. If you want more information, try Euler angles.




 * Yaw is the rotation about the Z axis, that is to say a rotation from left to right. (The yaw angle is the Psi ψ). Value -360.00 ° to 360, 00 ° (Def, 0.00 °).


 * Pitch is rotation about the Y axis, that is to say nose-up and nose-down. (The Pitch angle is the Phi φ). Value -360.00 ° to 360, 00 ° (Default, 0.00 °).


 * Roll is rotation about the X axis, that is to say wing up and down. (The Roll angle is the Thêta θ). Value -360.00 ° to 360, 00 ° (Default, 0.00 °).


 * : Once selected, this option virtually sets all parameters to zero, to allow you to enter your values ​​without having to calculate with the original parameters of the form. Once you have confirmed with, the entered values ​​will be added to the values ​​on the form.


 * The returns all values ​​to 0,0,0.
