Select open mesh boundaries and inspect the repair before applying it.
Rendered example views: 1 shows the original model and 2 the calculated result. The images illustrate the model geometry, not the editor interface.
A simple example
A plate is missing an end surface. You want to close that specific opening.
Step by step
- Open Repair and wait for the opening analysis.
- Select a suitable opening on the model or in the list. Check the highlighted boundary.
- Inspect the calculated preview. If there are several openings, check which ones remain open.
- Apply the repair step you want to keep.
What to check
Whole-model repair offers exact and approximate options. Approximate reconstruction can alter small details and gaps. Some openings cannot be closed safely automatically.
Preview and save
A preview is not a saved change. Wait for the checked result and choose Apply. If the button is disabled, read the message and check the selection or inputs. The offered STL download is paid; you will see the current price before purchase.
