Filling the Holes

We will now repair the three remaining holes, using the Fill Holes tool.

1. Click on the Fill Holes button on the TriFIX toolbar.

In the Fill Holes dialog box, there are three fill modes you can choose. As we know that the holes have only a few sides, and are not on a completely planar area nor a very curved area of the model, we will use the default Use central node option.

select how you want to fill theCopyCAD automatically displays the smallest hole's number of sides in the Fill boundaries of size box.

2. Rotate the model to view one of the holes.
   
   
3. Click and drag over the hole so that the boundary turns red.
   
   
4. Click on Apply to fill the hole using a central node.
   
   
5. Repeat the steps to fill the other two holes.
   
   
6. Click on OK on the message box, which is displayed now that the model is fully repaired.

You can now use the Mesh Status - Stats window, which is automatically displayed, to check the mesh quality, highlighting and deleting thin, intersecting, and badly connected triangles. If you delete any triangles you should stitch the model afterwards to repair the gaps, following the guidelines in this tutorial.

Note: You can also display this window using the Mesh Status tool .

When you have completed the repair of the hand grip, you can compare it with the original model. If it is of good quality, you can save it as an STL file that can be opened and used in other applications.

To complete the TriFIX session and examine the new model:

1. With the watertight model displayed in the Graphics window, click on the Close Toolbar button on the TriFIX toolbar.

   CopyCAD closes the toolbar and displays the fix_hand_grip model in the CopyCAD Explorer. This model contains all the repairs carried out by the TriFIX tools.

2. Click on the button next to both the hand_grip and fix_hand_grip models.

   This expands the details for each model, showing that you can view details about the model's Extents, Size, Points and Triangles.

3. Expand the Extents details for both models, and you will see that the TriFIX processes have not changed the extents of the model.
