Where appropriate, another option is to build a 3D solid model of the object.
Animated cutaways reveal internal parts and processes otherwise hidden from view.
CyberMill Studio will build solid models when a client needs, for instance, to import a 3D object into Finite Element Analysis applications. You may click on these thumbnail images to view higher-resolution images. Here's a sample of CyberMill Studio's 3D modeling expertise. Built in virtual 3D space from 2D plans, this truck model illustrates our capability to build an accurate 3D model of virtually anything you can design. In many cases, we access stock libraries of pre-made models, to keep a project budget as reasonable as possible.
