====== Orient3D 3D View ======

Orient3D's 3D View shows the surface model of the currently loaded object. It can also display the global coordinate system and [[other:dsx:orient3d:local_coordinate_system|local coordinate system]] (LCS).

===== View Camera =====

You can change the view camera using these commands:
  * **Rotation** left mouse button
  * **Zooming** right mouse button or mouse wheel
  * **Panning** Shift + left mouse button or middle mouse button
  * **Spinning** Ctrl + left button (spinning is rotating about an axis perpendicular to the screen)
  * **R** Resets the view camera such that the surface model is centered in the window.

===== Manual Local Coordinate System Manipulation =====

The LCS is the only object that can be manipulated in the view. It can be selected by clicking on it while holding the Ctrl key.

A trackball consisting of three axes and three circles is displayed when the LCS is selected.
  - Clicking near one of these axes or circles will select it and a mouse move will result in a constraint manipulation of the LCS (translation along selected axis or rotation in selected circle plane).
  - Clicking anywhere else within the trackball will enable free manipulation: free-form rotation with the left mouse button and free-form translation with the left mouse button while the Shift key depressed.
  - When the trackball is displayed, zooming the camera view with the mouse wheel.
  - Clicking anywhere outside of the trackball or pressing //Esc// will deselect the LCS and hide the trackball.\\

**Note**: Remember to use the //Save to Subject Object// command to save the manually manipulated LCS to the subject object in the subject file.
