Creating a Surface Automatically from a Mesh

Automatic Surface creates surfaces automatically from a mesh, as standard features, and then convert them into Imagine & Shape features.

  1. Select a mono-cell mesh, without non-manifold vertices or triangles, nor nonconnex zones.
  2. Select a type of stream lines.
    • Regular stream lines for a smooth and regular output.
    • Constrained stream lines: same as with regular stream lines with user constraints. Pick the mesh and use the context toolbar to create constraints.
    • Or none of the above.

      Select the Free edge tolerance check box and specify a value.

      Set a Target ratio: Ratio of measured points with a surface deviation under the Mean surface deviation value.

  3. Key in the Mean surface deviation between the surface to create and the input mesh, computed on all mesh vertices.
  4. Key in a Surface detail value: The higher the value, the higher the respect of details.
  5. When relevant, clear the Full internal tangency check box for a smaller output in terms of memory size and control points.
  6. When relevant, select the Fill holes check box.
  7. Select the Extend surface check box and adjust the extension with the slider.
    By default, Extend surface is not selected. The output surface is trimmed on the external and internal free edges of the mesh.
  8. Click Apply and expand More to access statistics.
  9. Select to display the deviations on the surface.
  10. Select to display the deviations on the free edges (only available when free edges exist).
  11. Select the Spikes check box to display the deviations between the mesh and the surface.
