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.
