Model Item
What Does This Widget Do?
The Model Item widget allows you to select an individual model item on the already loaded CAD model and apply properties directly to that item without applying the changes to any other part of the model.
When Should I Use This Widget?
Use the Model Item widget when you want to change the properties for an item on the model without change the properties on the model itself. For example, if you want to change the color of an item on the model.

Occluding
If set to true, the geometry of a widget is invisible, but at the same time hides any other augmentations behind it in the 3D scene.
Therefore, the background or camera feed appears where the occluded widget should be. This can be used to emphasize some augmentations by hiding surrounding 3D geometry.
Always on top
Overlays the widgets geometry on any other augmentations in the scene regardless of its depth in the 3D scene. If set to Yes, it is never hidden by other augmentations. Typically this can be used for labels or sensors that must always remain visible.
Opacity (1 Opaque - 0 Transparent)
A number between 0 and 1 that controls the level of transparency of the object. 0=completely transparent and 1=completely opaque. If set to semi-opaque (for example, opacity is set to <1), this will control whether the model item is drawn as a transparent shell (the default), or is entirely see-through.
Item Translucence
Makes the item translucent.
Color
Color of the model item.
