Hello, I'm running some complex Simscape Multibody simulations. The 3D output window is currently sufficient for what I'm doing, but objects keep leaving the screen.

With conventional plots, this would be no issue - I would just set

axis([-x +x -y +y -z +z]);
view([az el]);

and get the window view fixed at what I want it to be. Is something similar possible with the Simscape Multibody viewer?

The default viewpoint for the Mechanics Explorer is a fixed location and orientation in space. If your object is moving, it will move out of the field of view. You can define viewpoints that will track objects. See this video Exploring Simscape Multibody Models (2 minutes)

Try defining a new camera that tracks a frame. This page in the documentation will get you started.
