Create a transparent 3D solid, such as glass or acrylic.

Roger D. LaBrant gives us a method of producing solid objects that will render transparently every time.

"In order to create a 3D solid that is 'see-through,' such as glass or acrylic, I came up with a method that would give me a satisfying visual result. First, I draw the shape of the part, whether it's a simple rectangle or a more complex shape. If my part is not already a polyline, I use the Pedit command on my geometry and make my part a closed polyline. Secondly, I offset my polyline 1/32" to the inside of the original polyline. Next, I extrude both polylines to their desired thickness. Finally, I subtract the inner solid from the outer solid to get my finished 'see-through' part."
Notes from Cadalyst Tip Patrol: This tip can help in several ways. Since it essentially creates an opening in the object, the area will be see-through. It also reduces rendering time because there is nothing there to render. However, you won't be able to achieve a reflective look in the rendered image, because there is no surface to reflect onto. It all depends on what your needs are.

It works, one thing though - this method alter your model. You also can consider 3DCLIP or DVIEW commands to clip 3D model. However all methods are NOT perfect and all comes to what you need to accomplish
