Converting to Meshes or 3D Faces

There si a set of commands for changing the type of triangulation model created by such commands as Create TIN by Points. The type of created model can be converted to SubMesh (SubDMesh), Polyface Mesh (PolyFaceMesh) or a set of 3D Faces.

CAD drawing Converting to Meshes or 3D Faces 8 Command line: PC_TO_3DFACE

The command converts an object of SubMesh or Polyface mesh type to a set of 3D Face type objects.

CAD drafting Converting to Meshes or 3D Faces 15 Command lien: PC_TO_SUBDMESH

The command converts a set of 3D Face or Polyface Meshes type objects to one or several Submesh type object.

Command prompts:

Apply changes? <Yes> or [Yes/No/Save/saveDefault] <Yes>:

Yes – the command will be performed taking into account changes in the settings made by the user in the current session of the command work.

No – the command will be performed with the settings displayed immediately after running the command.

Save – saving settings to a document.

saveDefault – saving settings to the registry.

The command options are set in the Properties bar.

Options:

Split mesh for optimization	Yes (recommended) – the SubMesh obtained from the selected objects will be exploded to several smaller meshes for further comfortable work. The explosion criteria are set by the Split meshes by topology option. No – a single mesh will be created from the selected objects without splitting to parts.
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 500000 faces). · No – split only on the basis of limitations (no more than 500000 faces).
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.

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> or [Yes/No/Save/saveDefault] <Yes>:

Yes – the command will be performed taking into account changes in the settings made by the user in the current session of the command work.

No – the command will be performed with the settings displayed immediately after running the command.

Save – saving settings to a document.

saveDefault – saving settings to the registry.

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.
