Select the Inverted tetras option from the Category list to highlight triangular faces that are shared by two tetrahedral elements, but where the opposite nodes of the elements are on the wrong side of the triangular face.
This type of mesh defect can arise when nodes have been manually moved or merged.

Dialog elements
When the Inverted Tetras text is selected from the Category section of the dialog, the following options appear.
- Issues
- The number of tetrahedra with Inverted tetra. These elements will be highlighted within the part.
- Inverted Tetras
- The number of inverted tetra are listed.
- Isolate in Layer
- Click the Isolate in Layer button and the defective tetra will be placed onto a diagnostic layer. This enables an easier location and repair of the mesh.
Tip: Use this option if you want to view how the mesh has been altered, as only defective elements are shown on the model pane and, once repaired, will disappear from the view.
- Repair
- The Repair button is not active for Inverted Tetra as automatic repair is not available. Faults will have to be repaired manually.

- Inverted tetra cannot be repaired automatically. This option will be disabled unless other defect categories have been checked. Repair Checked will then only apply to the other defects.
- Settings
- Opens the Settings for 3D Mesh Repair dialog. From within this dialog the scanned defect limits can be adjusted.
- Close
- Closes the dialog without making any further repairs.
