Select "ModelItem" Widget Icon on Widgets menu of 3D CANVAS (press and hold LMB, drag "MopdelItem" icon onto required part of the model and then release mouse button:
You can see selected part of the model in 3D CANVAS :
As you can see in the "Model Item Details" pan - you now focused on Component (here - /24) and from now you can operate with this Component of Model separately.
For hide this part (i.e. "Component") you could prepare for example 2D Toggle button
(only for example I select two different PNG-icons as shown below. I don't understand but I need select "Not Pressed" and unselect "Pressed" properties of this toggle-button, but under such conditions it works right otherwise we cannot see hide-unhide function)
and bind it with modelItem-1 on the "PROJECT - Views" pan.
For hide you can use "Pressed" property of toggle-button for Hide
(for do it select In the binding menu "ForcedHidden" or "Visible" properties, then press "BIND" ):
And now you can see in the BINDINGS-pane on the gray bottom area new binding between selected component "modelItem-1" and the toggle-button:
Now you can use ToggleButton for hide/unhide the only component of the Model.
(Toggle-Button is "Not Pressed":)
(And now it is "Pressed" - our Component is hidden:)
(Now press yet another time our Toggle-Buttoh - we can see our Component again:)
