To Access IDD and Repair Geometry Failing Import Validation
1. Import a part or assembly model or open the model in Creo that belongs to one of the file formats that Creo Unite supports. Autodesk Inventor, CATIA V4 or V5, SolidWorks, NX, and Creo Elements/Direct are the supported file formats.
The model notification flag icon on the status bar highlights in red when the Notification Center detects a validation failure.
2. If the validation failure is due to incomplete or problem geometry or the bodies of the part or a part component of the assembly failing to solidify, right-click the part or the component model on the Model Tree and click > 
Repair Imported Geometry. The Import DataDoctor tab opens.
Repair Imported Geometry. The Import DataDoctor tab opens.3. To resolve problem geometry, perform geometry repair tasks in Import DataDoctor (IDD).
4. When the bodies of the part model or a part component fails to solidify, click Geometry Checks on the Analyze tab of IDD. The Troubleshooter opens.
5. Verify if the Solid node with open quilts diagnostic appears with a red dot. The number displayed in parenthesis next to the diagnostics indicates the number of bodies that failed solidification.
6. Click the Solid node with open quilts diagnostic in the Troubleshooter. The node with the bodies failing solidification zooms in. The text area of the Troubleshooter describes the defect as a node with one-sided edges. It recommends resolving the solidification failure using the editing tools in IDD.
7. Right-click the Solid node with open quilts diagnostic in the Troubleshooter tree and click Select Problem Geometry in the shortcut menu to select and highlight the node that includes the bodies failing solidification.
8. Use the > command in IDD to repair the one-sided edges of the bodies that fail to solidify.
9. Click OK to exit IDD.
10. Click OK on the Import tab.
