CAD drafting Converting a TIN Surface into a Mesh, a Polyface Mesh and 3D Faces 6 Command line: NG_CONVERT_FROM_SURFACETIN

The command converts a TIN Surface into Mesh, Polyface Mesh, 3D Faces objects.

The command options are specified in the Properties bar.

Options:

Save result as	Selection of what type of objects to convert to. When selecting Mesh or Polyface Mesh objects, additional options appear.
Delete source object	Possibility to choose whether or not to delete the source objects.

The convertion to SubMesh is selected.

Break SubMesh for optimization	If this parameter is enabled, the resulting mesh will be split into several smaller objects for more convenient work. It is recommended to enable this option.
Break meshes by topology	Method of splitting a mesh into smaller meshes: · Yes – split the mesh into pieces taking into account both the topology (the Maximal normals difference in mesh option) and the restrictions (no more than 32767 faces and vertices). · No – split only based on the restrictions (no more than 32767 faces and vertices).
Maximal normals difference in mesh (degrees)	The maximum permissible deviation of the normal of a mesh element from its average normal (in degrees), at which the element will be considered to belong to this mesh. The normals of the elements in each part into which a single mesh is split should not differ by more than this value. The option determines the number of pieces into which the mesh will be split if the Break meshes by topology parameter is set to Yes.
Tolerance for vertexes	The precision parameter within which closely located nodes (vertices) of objects will be merged during conversion. For example, the vertices of adjacent faces may not coincide within 1e-0.4, but if the Tolerance for vertices parameter is 1e-0.2, such vertices will be merged into one.

The convertion to Polyface Mesh is selected.

Break meshes by topology

Method of splitting a mesh into smaller meshes:

· Yes – split the mesh into pieces taking into account both the topology (the Maximal normals difference in mesh option) and the restrictions (no more than 32767 faces and vertices).

· No – split only based on the restrictions (no more than 32767 faces and vertices).

Maximal normals difference in mesh (degrees)

The maximum permissible deviation of the normal of a mesh element from its average normal (in degrees), at which the element will be considered to belong to this mesh.

The normals of the elements in each part into which a single mesh is split should not differ by more than this value.

The option determines the number of pieces into which the mesh will be split if the Break meshes by topology parameter is set to Yes.

Tolerance for vertexes

The precision parameter within which closely located nodes (vertices) of objects will be merged during conversion.

For example, the vertices of adjacent faces may not coincide within 1e-0.4, but if the Tolerance for vertices parameter is 1e-0.2, such vertices will be merged into one.
