Geometry Tools: Rebuild Faces
Description
Remaps the parametric space of selected NURBS surfaces such that the projection in world coordinates is more uniform.
Effectively smooths out the underlying representation of the surface, which may be useful for correcting faces that produce a poor quality mesh.
An example is illustrated below.
A NURBS surface imported from CAD contains irregular and overlapping control points. These can be visualised via Entity Display Settings: Geometry Display.
The surface mesh from this geometry is influenced by the nonlinear parametric space producing some distorted elements.
By rebuilding the face, the parametric space can be smoothed and made more regular.
The resulting mesh will be correspondingly more regular.

If selected, the degree and number of control points used in each direction is estimated before rebuilding the face.
This option may underestimate the number of control points, which may result in geometry that does not match the original face well. If this occurs, Custom should be used instead.
Custom
Controls the degree and number of control parameters used when rebuilding the surface representation.
Degree
The degree of the resulting surface in the u-v parametric directions.
For planar surfaces a degree of 1 is recommended. For non-planar surfaces a degree of 2 or 3 is recommended.
Control Points
The number of control points to fit in the u-v parametric directions.
Choosing insufficient number of control points may produce a face that does not match the original face well. If this occurs, try rebuilding with more control points.
