• Tool >> Fill Holes >> Surface command automatically fills holes in a selected shell or a selected region.

• A hole means a closed path formed by boundary edges; it is automatically detected by the program.

• Tool >> Fill Holes >> Surface command can be applied to both a selected shell and a selected region.

Step   

Execute Tool >> Fill Holes >> Surface command as follows:

1. Select Tool >> Fill Holes >> Surface from the menu or click the corresponding icon from the polygon Tool1 toolbar.

2. All the boundaries of the selected shell or region appear on the model like shown below.

3. Select holes with mouse then select Done on RMB menu. If a user wants to fill all the holes, click the right mouse button and select All on the following popup menu.

       

    Bridge Hole options bridge two edges on the same boundary of the hole when the hole is too large or complex. You can select Curvature or Flat as bridge type.

    Click Next >> button  in the following dialog box to search holes.

       

4. The following dialog box appears after you pick a hole.

       

When Flat method is checked, the selected hole is filled with a flat face.

When Smooth method is checked, faces used to fill holes are generated as continuous as possible to the surrounding shape of the hole.

The Curvature option is a curvature based filling method that ensures the polygonal structure used to fill holes in curved regions is curved to match the surrounding area.

Check Smooth hole boundaries before filling option to smooth edges around holes before filling.

Check Except the Biggest Hole option in order not to fill the biggest hole on the model.

Check Small Hole Only option to fill only the hole whose boundary edge count is fewer than a given number.

5. Press OK button to complete the command.
