Automatic faceted body cleanup

The Check Facets and the Auto Fix tools are quick ways to find and fix problems in faceted bodies.

Checking Facets tool:

Use the Check Facets tool to list problems with the faceted body that will adversely affect the 3D Printing process.

Problems detected include the following:

• Multiple pieces (i.e. facet regions or shells)
• Non-watertight facets
• Self intersections
• Over-connected (i.e. non-manifold) edges

To check facets:

1. Select a Faceted body in the Structure treeDisplay in the Structure panel that shows you each of the objects in your design. You can expand or collapse the nodes of the tree to view the objects. You can rename objects, create, modify, replace, and delete objects, as well as work with components.
2. Click the Check Facets tool
3. A dialog appears listing any issues found
4. Click Zoom to fit in the dialog to zoom in on selected problems in the list

 The Check facets tool can also be used in an Action-ObjectAnything recognizable by the tools. 3D objects include vertices, edges, faces, surfaces, solids, layouts, planes, axes, and origins. 2D objects include points and lines. workflow by entering the tool and then selecting the faceted body.

Auto Fix tool:

Use the Auto Fix tool to automatically search for, and fix any facet defects.

The Auto Fix tool performs the following sequence:

1. Fix self-intersections
2. Close holes using the methods described the find and fix example below.
   • If there is surrounding curvature, the hole is closed using the Patch method.
   • If the surrounding edges are approximately planar, the hole is closed using the Cap method.
3. Recheck for self-intersections
4. Fix self-intersections
5. Remove void shells
6. Fix inverted normals
7. Fix non-manifold edges and vertices

To Auto Fix a faceted body:

1. Click the Auto Fix tool
2. Select a Faceted body in the Graphics window
3. Problem areas are fixed
