Fair Solid 
Access: Open this function from the following location:
-
Select Solid > Objects > Fair Solid from the menu bar.
Fair (simplify) objects, faces, wires, edges or curves and keep the result as a solid.
Some models may contain faces or edges that should appear analytic but are actually represented as splines (NURB). Fair Solid converts such faces to their corresponding analytic forms (plane, cone, torus, or sphere) wherever possible. For example, in the model below, all faces in the part are of the NURB (spline) type. After a Fair Solid operation, the yellow entities become cylindrical faces, the green become faces and the blue become planar faces.

In addition, some models may also contain "procedural" faces that are the result of a Round, Sweep, Blend, Bend or other operation. These procedural faces are very accurate (with almost no tolerant geometry on them) but are sometimes "time consuming" (heavy) faces. After a Fair Solid operation, these faces become analytic or NURB type faces, but are also more tolerant faces. |
Fair Solid can also be used on wireframe entities; a 2D/3D Spline may be converted to lines and arcs and the wireframe remains as one body.
Fair Solid results in a:
-
Reduction in data size.
-
Speed improvements of downstream operations.
-
Improved success rate of downstream operations.
-
The object becomes more tolerant.
Important: Unlike the (Face) Fair or (Curve) Fair operations, in the Fair Solid function, when fairing a Spline face (NURB) or a spline curve with a specific tolerance, the result may become analytic (if it is within the tolerance). However, if it cannot become analytic, there is no change to the entity.
