Menu: Geometry->Create->Geometry from mesh
One node-one point
Creates a geometrical point for each node selected. Layer, material and groups of nodes are preserved in points.
One element-one line
Creates a geometrical line for each line mesh element and points.
Quadratic elements are converted like there were linears, ignoring mid-edge nodes
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 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
Nodes->grid surfaces
To create a grid of surfaces from a cloud of 3D nodes. The user will be asked for the cell size
The z of the grid will be extrapolated averaging a collection neighbor nodes
Triangles->grid surfaces
To create a grid of surfaces from a cloud of 3D triangles. The user will be asked for the cell size
The z of the grid will be get from the triangle where the grid corner is projected (in 2D), or from a close node.
