Wire Frame v. Solid Model

Wire frame and solid models give visual renderings of 3D objects for computer-aided design and manufacturing programs. The main difference between wire frame and solid models concern the amount of surface detail.

Wire Frame:

    • Just the outlines of the 3D object with information about the edges, nodes, and vertexes
    • Transparent: no coloring or solid fill
    • No indication of material thickness
    • No provision for bend allowances
    • No detail on hole specifics (i.e. countersink, thread, etc.)
    • Files are light in size and regenerate easily on the screen

Solid Model:

    • More detailed and realistic representation of an object
    • Not transparent: include information about edges, nodes, and vertexes in addition to coloring, solid fill, surface features, and volume
    • Material type still needs to be added in the notes
    • Welding fillets typically not shown
    • Files are larger than wire frame files and regenerate less easily
