NURBS patches
This option converts all our mesh model (only surface mesh, triangles and quadrilateral) to a geometry model, obtaining a NURBS surfaces based definition. Creates a group of new layers called "Reconstruction", inside you will see two new layers: the first "All Lines And Points" contains lines and point and the second "Reconstructed Nurbs" the surfaces. If some surface couldn't be reconstructed it will appear a third layer called "SurfMeshes Not Reconstructed" containing the remaining parts converted in Surfmeshes, see more infomation information about Surface mesh.
One element-one surface
Creates a geometrical surface for each surface element (triangles or quadrilaterals) and its boundary curves and points.
Quadratic elements are converted like there were linears, ignoring mid-edge nodes
