• Solid modeling :

Solid modeling is the easiest type of 3D modeling among wire‐frame modeling, surface modeling, and solid modeling. 3D objects can be created using basic 3D shapes, viz, boxes, cones, cylinders, wedges, spheres, donuts (tori), etc.

 2D solid modeling is a way of modeling in which a 2D object is converted into a 3D object by sweeping it along a path, or by extruding it along any axis, or by revolving it about an axis.

 It is possible to convert from a solid model to surface model; and from surface model to wireframe model, but, the reverse conversion from wireframe model or from surface model to a solid model cannot be done
