Wireframe Model
Also called wireframe view, wireframe
A wireframe model is a see-through view of a 3D design that shows only its edges and structural lines, with no solid surfaces. Designers use it to check proportions, spot hidden geometry, and read what is going on inside a piece.
What a wireframe shows
Turn the surfaces off and you are left with lines: the outline of the band, the edges of every prong, the seats under the stones. Because nothing is opaque, you can see the back of the piece through the front.
It is a working view rather than a presentation view. Nobody sells a ring with a wireframe, but almost every CAD artist checks one before calling a model finished.
Why we look at it before rendering
Wireframe is the fastest way to catch problems that a shaded view hides. Duplicate surfaces sitting on top of each other, stones floating just above their seats, leftover construction curves, prongs that do not quite reach the girdle.
Any of those turn into visible faults once photorealistic lighting is applied, and they are far cheaper to spot at this stage than after a full render. Checking wireframe first is part of why a first draft usually only needs one of the two included revision rounds.
Questions about Wireframe Model
Can I get a wireframe image of my design?
The standard delivery is 9 HD images and 3 videos of the finished piece on a white background, not technical views. Wireframe is something we work with internally to check a model before rendering.
Is a wireframe the same as a CAD file?
No. The CAD file is the full 3D model. A wireframe is just one way of displaying it, with the surfaces switched off.
