Problem getting solid object


hi guys iam new to sketchup , and i need help making this object a solid object , i tried using solid inspector but seems no success it gives me error and i dont understand what should i do


I think you might have a component in a component. Go into the component, then explode the geometry.


Indeed, the extension is displaying the fact that in addition to the object’s raw geometry (edges and faces), there are three groups and/or components within the object. They are highlighted in red. You can press the TAB key to have the extension cycle the selection one-by-one among the three nested groups or components.

By the way, the object’s edges and faces do apparently form a solid shape, if you ignore the three nested groups or components. If the raw geometry did not, SolidInspector would list additional issues.
