Hide a part by Model Item

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:)
