The Selection of Problem Geometry

You can right-click a diagnostic in the Troubleshooter tree and click Select Problem Geometry in the shortcut menu to select and highlight the defective geometry in the model.

Diagnostics	Geometry Selected in the Model
Bad surfaces	Surfaces
Bad two-sided edges	Green wireframes
Bad wireframe curves	Black wireframes
Poorly tessellated edges	Green wireframes to which the poorly tessellated edges belong
Small loops of one-sided edges	• A green or black wireframe that shares a vertex with a one-sided edge loop when the small loop is made up of edges from many surfaces. • A single edge of a one-sided edge loop or all the edges when the small loop is an internal boundary of a single surface.
Short one-sided edges	Edges
Bad vertices	The corresponding wireframes
Unsatisfied wireframes	Black wireframes
Unsatisfied tangency	Wireframes
Gaps not added to wireframes	Gaps
Almost tangent edges	Green and black wireframes without constraints to which the edges belong
Small surfaces	Surfaces
Narrow surfaces	Surfaces

When you select the defective geometry, it zooms in and is highlighted in red. The text area of the Troubleshooter displays the diagnostic type and the suggested solution for the selected diagnostics.

For the diagnostics identified as almost tangent edges, the Select Problem Geometry RMB option selects green and black wireframes at which the corresponding surfaces are almost tangent to each other. These wireframes do not have any tangency constraints. The recommended solution for this defect is that you add the tangency constraints to the relevant wireframes to which the almost-tangent edges belong. You can then use the Repair or the Match tool and, if required, the Repair Tangency option to make the corresponding surfaces tangent to each other at these edges. You can also use the Align tool.
