ShrinkWrap
New in 8

ShrinkWrap creates a watertight mesh around open or closed meshes, NURBS geometry, SubD, and point clouds.

ShrinkWrap is ideal for creating:

  • Meshes for 3D printing.
  • A solid union mesh from multiple objects.
  • A solid mesh from 3D scan data fragments.
  • Meshes without internal self-intersections.
  • Offset meshes for shelling.
  • Meshes from point clouds when reverse engineering.
  • Valid closed meshes from broken or often hard-to-repair geometry.
  1. Inflated Point Clouds
  2. Interior Shells
  3. Remove Self-Intersections
  4. Scan Data to Clean QuadMesh

ShrinkWrap in Action

Try It

  1. Download Rhino 8 Evaluation for Windows or Mac.
  2. Download and open the ShrinkWrap-Demo.3dm model. This is a 3D scan of a shoe last used in shoemaking. Notice the major gaps and broken, uneven mesh geometry. You can fix that with ShrinkWrap.
  3. Select all the objects in ShrinkWrap-Demo.3dm model (run -_SelAll).
  4. Run the ShrinkWrap command (the button can also be found in the Mesh Tools toolbar). The ShrinkWrap dialog appears:
  5. Set the Target Edge Length to `0.10'. This option effects the density of the resulting mesh.
  6. Set the Offset value to -0.05. Offset pulls the results of inflated points back to the original.
  7. Set the Smoothing iterations to 10. A larger value will smooth out lumps and pits where the large hole in the toe was.
  8. Check the Inflate Vertices and Points option. This converts all non-mesh objects to meshes and then samples each new vertex location as a point cloud to construct the new mesh.
  9. Click the OK button. In a few moments, you should have a closed, watertight mesh.
  10. Ask questions and give feedback on the Discourse Forum.
