Description

The Mesh FromPartShape command creates a non-parametric mesh object, a Mesh Feature, from a shape object.

Usage

  1. Optionally select one or more objects.
  2. There are several ways to invoke the command:
    • Press the Mesh FromPartShape button.
    • Select the Meshes → Create mesh from shape... option from the menu.
  3. The Tessellation task panel opens.
  4. While the task panel is open you can create a (new) selection or change an existing selection.
  5. Select the tab for the mesher program you wish to use.
  6. Specify the required settings. See Mesher programs.
  7. Press the OK button to close the task panel and finish the command.

Mesher programs

These are the available mesher programs and their settings:

Standard

  • Surface deviation: the maximum linear deviation of a mesh section from the surface of the object.
  • Angular deviation: the maximum angular deviation from one mesh section to the next. Used when meshing curved surfaces.
  • Relative surface deviation: if checked, the maximum linear deviation of a mesh segment will be the specified Surface deviation multiplied by the length of the current mesh segment (edge).
  • Apply face colors to mesh: If checked, the mesh will get the face colors of the object.
  • Define segments by face colors: If checked, mesh segments will be grouped according to the colors of the object's faces. These groups will be exported for mesh output formats supporting this feature (the OBJ format for example).

Mefisto

  • Maximum edge length: The maximum edge length of the faces in the mesh. If this number is smaller the mesh becomes finer. The smallest value is 0.
  • The Estimate button...

Netgen

Gmsh

  • Press Esc or the Cancel button to abort the command.
