7. Session Tree#

The Session Tree panel manages the sessions, windows, and views created during a work session. A session represents the current state of NaxToView — including all open windows, views, and loaded models. Sessions can be saved to a .n2v file and restored later.

The tree is organized into three levels, as illustrated below:

The Session Tree panel showing the top-level session node

  • Session — the top level, representing the current work session

  • Windows — one or more 3D windows within the session

  • Views — one or more viewports within each window

Session Tree expanded to show a session node containing windows, each with multiple views

7.1. Session#

Right-clicking the session node in the Session Tree reveals the following options:

  • Create Window — adds a new 3D window to the session

  • Rename Session — renames the current session

7.2. Window#

Right-clicking a window node in the Session Tree reveals the following options:

  • Create View — adds a new viewport inside the selected window

  • Copy and Paste Window — duplicates the window, including all its views, and adds the copy to the current session

  • Rename Window — renames the selected window

7.3. View#

Right-clicking a view node in the Session Tree reveals the following options:

  • Expand View — expands the view to fill the application window. Once active, right-clicking the view shows Not Expand in its place; select it to restore the original multi-view layout.

  • Synchronize — links camera movement across all views in the session, so rotating or zooming in one view affects all others. Once active, right-clicking the view shows Stop Synchronize in its place; select it to disable synchronisation.

  • Hide View / Show View — dynamically hides or shows the selected view in the viewport. When the view is visible, the context menu displays Hide View; once hidden, right-clicking the view node shows Show View to restore it. This allows you to manage which views are displayed at any time without deleting them.

  • Delete View — permanently removes the view from the window.

  • Rename View — renames the selected view.

  • Clone View — clones an existing view. In this first version, the clone replicates the loaded model and the current camera position, allowing you to quickly generate alternative visualization configurations from the same base.

7.4. Saved Plots#

When using the Plot & Save feature in the Contour Plot menu (see 9.1.7. Plot & Save), each saved result is added as a new node inside the corresponding View in the Session Tree.

Right-clicking a saved plot node provides the following actions:

  • Activate — re-plots the stored result on exactly the same elements as originally selected.

  • Delete — removes the saved plot from the Session Tree.

This allows you to store multiple result representation states and switch between them without repeating the selection or configuration.
