Exploring the Benefits and Uses of ShrinkWrap in Rhino 8

Rhino 8 Shrink Wrap Feature

The introduction of the ShrinkWrap feature in Rhino 8 brings a new level of proficiency to 3D digital design and modeling. ShrinkWrap is an innovative tool that creates a watertight mesh around open or closed meshes, NURBS geometry, SubD, and point clouds. This advanced tool offers a plethora of real-world applications for designers, engineers, and modelers across various industries.

Applications of ShrinkWrap

ShrinkWrap's versatility makes it ideal for a wide range of applications, including:

  • Creating meshes for 3D printing
  • Uniting multiple objects into a single solid mesh
  • Developing solid meshes from 3D scan data fragments
  • Creating meshes without internal self-intersections
  • Generating offset meshes for shelling
  • Creating meshes from point clouds in cases of reverse engineering
  • Creating valid, closed meshes from broken or hard-to-repair geometry

The ShrinkWrap tool can handle complex tasks with ease, such as inflating point clouds, removing self-intersections, converting scan data to clean QuadMesh, and generating interior shells.

How to Use ShrinkWrap in Rhino 8

Rhino 8 Shrink Wrap Feature

To get started with ShrinkWrap in Rhino 8, download the Rhino 8 Evaluation for Windows or Mac. Once installed, open the ShrinkWrap-Demo.3dm model—a 3D scan of a shoe last used in shoemaking. Despite the major gaps and uneven mesh geometry, the ShrinkWrap command can fix this.

Follow these steps to use ShrinkWrap:

  1. Select all objects in the ShrinkWrap-Demo.3dm model using the -_SelAll command
  2. Run the ShrinkWrap command (also found in the Mesh Tools toolbar). This will open the ShrinkWrap dialog
  3. Set the Target Edge Length to 0.10. This parameter influences the density of the resulting mesh
  4. Set the Offset value to -0.05 to adjust the mesh to the original
  5. Set the Smoothing iterations to 10. This will help smooth out areas with large holes or inconsistencies
  6. Check the Inflate Vertices and Points option. This converts all non-mesh objects to meshes and samples each new vertex location as a point cloud to construct the new mesh
  7. Click the OK button. After a few moments, you'll have a closed, watertight mesh
