To Convert Model to Polyface Mesh
Ribbon: Topoplan – Create TIN > 
Converting to POLYFACEMESH
Menu: Ground – Creating TIN > Converting to POLYFACEMESH
Toolbar: Creating TIN > Converting to POLYFACEMESH
Command line: NG_TO_POLYFACEMESH
The command converts a set of 3D Face or SubMesh type objects to one or several Polyface mesh type objects.
Command prompts:
Apply changes? Yes – conversion will be performed with the current settings.
or [Yes/No]: No – if the settings have been changed, they will not be preserved. Conversion will be performed with the settings that displayed right after the command started.
The command options are set in the Properties bar.
Options:
| Split meshes by topology | A method of exploding a mesh into smaller meshes: · Yes – split a mesh into parts taking into account both topology (Maximum difference of normals in mesh option), and limitations (no more than 32767 faces and vertices). · No – split only on the basis of limitations (no more than 32767 faces and vertices). |
| Maximum difference of normals in mesh (degrees) | The maximum allowable 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 elements in each part, into which a single mesh will be split, should not differ by more than a given value. The option determines the number of pieces into which the mesh will be split, if the Split meshes by topology option is set to Yes. |
| Vertex tolerance | Accuracy parameter within which closely located nodes (vertices) of objects will be combined during conversion. For example, the vertices of neighboring faces may not match within 1e-0.4, but with the Vertex tolerance value equal to 1e-0.2 such vertices will be merged into one. |
