5.4.1 View Modes
Click the Switch navigation mode button and select one of the four view modes:
- 3D cursor mode. Allows you to drag and rotate orthogonal cutting planes using the mouse.
The Switch navigation mode button will look as follows: .
- On click 3D cursor mode. Allows you to move orthogonal cutting planes similarly to the
3D cursor mode, but the plane lines are visible only during the dragging (while the left
mouse button is pressed). The Switch navigation mode button will look as follows:
- Planes cursor mode. The cutting planes are displayed permanently. Their moving is
described in the next section. Rotation of planes is similar to the 3D cursor mode and
described in Section 5.4.2. The Switch navigation mode button will look as follows:
- Curve mode. This mode is described in Section 5.5. The Switch navigation mode
button will look as follows: .
5.4.2 Working with Planes in 3D Cursor Mode
To move orthogonal planes, click the left mouse button at the point to move the planes to, or move
the mouse holding the left button. When the button is released, the position of the planes is fixed. To
rotate a plane maintaining orthogonality:
- Locate the cursor on the radial bidirectional arrow on the plane line (see red arrows in
Fig. 5.5). The bidirectional arrow will be highlighted.
- Move the cursor holding the left mouse button to rotate the plane by the required angle.
The images in the other planes will change.
- Release the left mouse button to fix the current position of the plane.
Figure 5.5: Rotate an orthogonal plane
To rotate a plane without maintaining orthogonality follow the steps above holding the Shift key
while performing the 2nd step.
To undo the rotation of all planes, click the Undo rotation button on the toolbar . Note
that all other view changes will be undone as well.
5.4.3 Working with Planes in the Cutting Plane Mode
The Viewer allows you to move planes one by one in the image view modes. To do this:
- Locate the cursor on the plane line to highlight it.
- Move the line holding the left mouse button.
Scroll the images in some window to see how the target plane is moving in other windows.
For convenience, zoom the image in and out by rolling the mouse wheel holding the Ctrl
