trying to figure out....

certain shapes. I was wondering how do you figure out how to model advance things? I have been trying vertice modeling mapping out the object but still having issues.

Such as? It’s hard to answer without more specific examples.

I’m new to 3D modelling so my advice might not be useful but for what it is worth, maybe some 2D art experience might help here. Have you ever tried drawing something with an awkward shape by first breaking it down into simple geometric shapes? A cheap sketchbook might be of value here.
