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.

Example


A practical example of using this command is in the tutorial Aeroplane.

Other explanation on Placement

In Combo View


Click a shape to select it. The function Placement can be accessed in several ways:

Scripting Placement as y/p/r and Matrix

  • or, in the window Combo View → Properties → Data → Placement → ...,

Task_Placement

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

and, the Toolbox of work Placement is displayed.

Click Placement (the title, not the little arrow) Tache_Placement, and a button with three dots appears, click on this button, and the Placement Dialog is displayed.

Placement

Translation:

  • TASKS X Translation in X direction (Click to enlarge) Moves the coordinate system of the object in the X direction (front to back) in relation to the axis coordinates of origin 0, 0, 0.
    (Default: The location of the object )
  • TASKS Y Translation in the Y direction (Click to enlarge) Moves the coordinate system of the object in the Y direction (left to right), relative to the coordinates axes origin 0, 0, 0.
    (Default: The location of the object)
  • TASKS Z Translation in the Z direction (Click to enlarge) Moves the coordinate system of the object in the Z direction (top to bottom), compared to the original coordinate axes 0, 0, 0.
    (Default: The location of the object)

Center

  • TASKS X: Move the center of rotation in the direction X, from the coordinates of the selected object. (Default, 0.00).
  • TASKS Y: Move the center of rotation in the direction Y from the coordinates of the selected object. (Default, 0.00).
  • TASKS Z: Move the center of rotation in the direction Z, from the coordinates of the selected object. (Default, 0.00).
  • TASKS User Defined ... : Allows you to change the three axes ( X, Y, Z) in a single operation User Defined.

Rotate

We select * Axis of rotation and angle Tache_Placement Option rotation axis and angle (Default).

  • TASKS Axis: X: The rotation will be the X axis.
  • TASKS Axis: Y: The rotation will be on the Y axis.
  • TASKS Axis: Z: The rotation will be on the Z axis. (Default).
  • TASKS Angle: Angle of rotation in degrees from -360.00 ° to 360.00 °. (Default: 0.00°).

We have a second option to adjust our rotation parameters . Select Euler Angles 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.

Option Euler angles


Yaw

  • TASKS yaw axis 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 ° (Default, 0.00 °).


Pitch

  • TASKS pitch axis 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

  • TASKS roll axis 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 °).


  • TASKS Apply incremental changes to the placement of the object: 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 OK, the entered values ​​will be added to the values ​​on the form.
  • The Reset returns all values ​​to 0.00.
