# Import Diagnostics
This feature supports repairing defective surfaces and stitching the repaired surfaces into a closed shape.

How to use:
Import the model and click Evaluate - Input Diagnostics.
The system will automatically analyze defective surfaces and gaps, displaying them one by one.
Click Try to Heal All Surfaces and Try to Heal All Gaps—the system will automatically repair the invalid surfaces and fill the gaps.
Note: Input diagnostics can only be initiated when importing external formats.
