AltView is a Blender add-on that switches between predefined views and locks or unlocks viewport rotation from a single hotkey. It covers 200 predefined views, including standard front, top and left angles alongside diagonal angles, and is aimed at users of 3DConnexion devices.
The add-on works in two presses. The first press switches the camera to the nearest predefined orthographic view, enables orthographic mode, and locks rotation to prevent accidental perspective changes. The second press unlocks rotation and restores perspective mode.
AltView is compatible with Blender 4.2.5 LTS and newer and is released under the GNU General Public License v3.0 or later. It installs by dragging and dropping into Blender or by downloading and installing from disk. Version 1.0.1 fixed a hotkey setting.
