Manipulating Views

You can constrain views, in order to set a specific viewpoint.

By default, the Standard View Manipulation is active. With this mode, the four main manipulations, used to define the 3D viewpoint, are available:

  • translation
  • zoom (in or out)
  • rotation
  • focusing on a specific point (double-click on mouse button 2).

Before you begin: open an existing 3D shape.
  1. Press and hold button 2 then 1 of the mouse, and drag to rotate freely in space.
  2. From the View section of the action bar, click Rotation About Z Screen Axis .
    • Still holding both mouse keys, you can now only rotate about the Z screen axis.
    • If you release key 1, but still hold key 2, you are able to zoom as usual.
  3. To redefine the tuning, refer to the FreeStyle Shape Design settings and the Setting the Handles Attenuation Factor chapters. The tuning defines the movement amplitude, i.e. if you decrease the value, movement will seem slower.
    • This is especially useful when working in Stretch view mode.
    • This attenuation step definition is also affected by the Tuning value defined in Me > Preferences > App Preferences > 3D Modeling > Styling > FreeStyle Shape Design, General tab, Tuning section.
  4. Similarly you can click the Rotation About X Screen Axis or Rotation About Y Screen Axis icon to rotate around the screen X or Y axis respectively.
  5. If you click the Zoom And Translate icon , no rotation is allowed.
    Important:
    • Simply click the Standard View Manipulation icon to reset the default options.
    • Still holding down mouse keys 1 and 2, use keyboard shortcuts to manipulate views according to pre-set steps, select Rotation About Z Screen Axis or Rotation About X Screen Axis or Rotation About Y Screen Axis:
      • Using the up and down arrows: 90° around the X screen axis.
      • Using the right and left arrows: 90° around the Y screen axis.
    • Still holding down mouse keys 2, using the right and left arrows, you can zoom in and out.
    • When changing viewpoints, you may wish to come back to a preceding viewpoint. To do this, simply click to move backward or to move forward in the viewpoints.
    Warning: If you define a manipulation mode in a multi-view configuration and you switch to another view, the selected mode is no longer active.
