About Repairing Geometry
After you import geometry, topological connections in the imported geometry are non-existent or can fail due to the varying quality of data from different systems. Wireframes in Import DataDoctor (IDD) represent the topological connections between surfaces in the import feature. Wireframes allow you to define or redefine these connections as required. You can display wireframes over the actual geometric edges of the imported quilts. You can also display and define tangency conditions on the wireframes. The color of the displayed topological connections and associated tangency conditions indicates whether the geometry satisfies these conditions. If it does not, you can use IDD to modify the imported geometry, repair the topological connections of the imported data, and satisfy the topological and tangency conditions defined by the wireframes.
The Heal tab on the Import DataDoctor tab consists of the following repair geometry commands:
• 
Repair—Repairs unsatisfied topological connections and tangency conditions of the imported data.
Repair—Repairs unsatisfied topological connections and tangency conditions of the imported data.• 
Match—Repairs problem surfaces and the unsatisfied topological connections of surfaces and fixes the associated tangency conditions in the imported models. Use the Match tool when Repair fails, especially when the problem geometry includes surfaces with more than four sides.

Close—Repairs wireframes, closes gaps, and removes sliver surfaces as a single operation.
Close—Repairs wireframes, closes gaps, and removes sliver surfaces as a single operation.You can also access these commands as shortcut-menu options after you select and right-click the relevant geometry on the GTS Tree or the graphics window.
 | The display options for wireframes, frozen states, vertices, and tangency are not available on the Graphics toolbar when you use the repair geometry commands on the Heal tab. |
If you set the Heal options in the Topology tab of the import profiles, you can repair the geometry of the part and assembly models during their import.
