    About Creating Meshes by Conversion

    Convert solids, surfaces, and legacy mesh types to mesh objects.

    You can use the MESHSMOOTH command to convert certain objects to mesh objects. Convert
    3D solids, surfaces, and legacy mesh objects to the enhanced mesh object in order
    to take advantage of capabilities such as smoothing, refinement, creasing, and splitting.

    Object Types That Can Be Converted

    You obtain the most predictable results when you convert primitive 3D solid objects
    to mesh objects.

    You can also convert other types of objects, although the conversion results may differ
    from what you expect. These objects include swept surfaces and solids, legacy polygon
    and polyface mesh objects, regions, closed polylines, and objects created with 3DFACE
    For these objects, you can often improve results by adjusting the conversion settings.

    Adjust Mesh Conversion Settings

    Settings can be changed using the Mesh Tessellation Options dialog box (MESHOPTIONS).

    For example, if the smooth mesh optimized mesh type (FACETERMESHTYPE system variable)
    results in incorrect conversions, you can set the tessellation shape to be Triangle
    or Mostly Quads.

    You also can control the adherence to the original shape by setting the maximum distance
    offset, angles, aspect ratios, and edge lengths for new faces. The following example
    shows a 3D solid helix that has been converted to a mesh using different tessellation
    settings. The optimized mesh version has been smoothed, but the other two conversions
    have no smoothness. Notice, however, that the mostly quads conversion with the lower
    tessellation values creates a mesh object that adheres most closely to the original
    version. Smoothing this object improves its appearance even more.

    Similarly, if you notice that a converted mesh object has a number of long, slivered
    faces (which can sometimes cause gaps), try decreasing the maximum edge length for
    new faces value (FACETERMAXEDGELENGTH system variable). If you are converting primitive
    solid objects, this dialog box also offers the option of using the same default settings
    used to create primitive mesh objects.

    When you select conversion candidates directly from this dialog box, you can preview
    the results before you accept them.
