Check and Repair Section

The Check and Repair section of the action bar provides commands for checking your geometry and for healing and joining faces.

Geometry Checker
Checks the geometry for non-manifold edges, sharp corners, slivers, and inclusions.
See Checking 2D and 3D Geometry.
Face Checker
Checks the topology of faces and searches for self-intersections and geometrical discontinuities in the boundaries of faces.
See Checking the Topology of Faces.
Surface Connection Checker
Checks connections between surfaces and finds connectivity problems.
See Checking Connections Between Surfaces.
Wall Thickness Analysis
Analyzes the thickness of regions in your model (edges, faces, and volumes) and searches for narrow regions that generate small elements in the mesh.
See Analyzing Wall Thicknesses.
Healing
Heals surfaces by filling small gaps.
See Healing Geometry.
Join
Joins or groups adjacent curves or surfaces.
See Joining Curves or Surfaces.
Local Join
Merges a set of selected edges and heals surfaces.
See Performing a Local Join.
