Classification Mesh
Ribbon: Topoplan – Modify TIN > 
Classification Mesh
Menu: Ground – Editing TIN > 
Classification Mesh
Toolbar: Editing TIN > Classification Mesh
Command line: NG_MESH_CLS
The command is used to divide the mesh into classes: for example, if you want to separate the road surface from the lawn. For classification, in the drawing it is necessary to create polylines (necessarily closed), along which the mesh will be cut. After the mesh is classified, the resulting areas can be decomposed into layers to control the display (you can adjust the visibility, color, transparency, etc.)
The command options are set on the Properties toolbar.
Options:
|
Project profile on |
Determines how the polyline cutting the mesh will be projected on it: WCS – on XY plane of the world coordinate system. UCS – on XY plane of the user coordinate system (if available in the drawing). Viewport – on the viewport plane. |

The option influences on objects to be created in the process of performing the command: a Submesh or Polyfacemesh can be created. |
