Selectively Show and Hide Model Components
Visualization filtering is a Mechanics Explorer feature that enables you to selectively show and hide solids, bodies, and multibody subsystems. This tutorial shows you how to use this feature to control the visualization of a Simscape™ Multibody™ model, for example, to observe a model component that might otherwise remain obstructed during simulation. For more information, see Selective Model Visualization.
Radial Engine Visualization with Two Cylinders Hidden
Open Example Model
In this tutorial, you filter the visualization of the Simscape
Multibody radial engine featured example. To open this model, at the
MATLAB® command prompt, enter
The model contains two top-level subsystems—the housing subsystem, named Housing_and_Cylinders_Assembly, and the piston subsystem, named Piston_Crank_Assembly. The housing subsystem contains five half cylinders. The piston subsystem contains five pistons that travel inside the half cylinders.

Update Example Model
To open Mechanics Explorer, the Simscape Multibody visualization utility you must first update the example model. In the Modeling tab, click Update Model (Ctrl + D). Note the tree-view pane on the left side of Mechanics Explorer. You access the visualization filtering menu by right-clicking a node on this pane.
Radial Engine Model Visualization
Hide Half-Cylinder Subsystem
In the tree-view pane, expand the Housing_and_Cylinders_Assembly node.
Right-click the Half_Cylinder_A node and select
This. Mechanics Explorer hides the half-cylinder subsystem
and the solids it contains, corresponding to the nodes Fins and
Half_Annular_Cylinder. The hidden-node names are grayed out in the tree-view
pane. The figure shows the resulting model visualization.
Radial Engine with Hidden Half-Cylinder Subsystem
Show Solid in Hidden Subsystem
In the tree-view pane, expand the Half_Cylinder_A node. Then, right-click
the Half_Annular_Cylinder node and select
This. The half-cylinder solid is now visible, but the
remainder of its parent of its parent subsystem—in this case, just
the Fins solid—remains hidden. The newly visible half-cylinder node
name is no longer grayed out in the tree-view pane. The figure shows the
resulting model visualization.
Radial Engine with Visible Solid in Hidden Half-Cylinder Subsystem
Show Only Piston Subsystem
In the tree-view pane, collapse the Housing_and_Cylinders_Assembly node.
Then, right-click the Piston_Crank_Assembly node and select
Show Only This. Mechanics Explorer shows the
selected node and hides the remainder of the model. In the tree-view pane,
the name of the selected node is the only that is not grayed out. The figure
shows the resulting model visualization.
Radial Engine with Only Piston Subsystem Visible
In the tree-view pane, right-click any node and select
Everything. All hidden components become visible. The
corresponding nodes are no longer grayed out in the tree-view pane. The
figure shows the resulting model visualization.
