Tool >> Fill Holes >> Volume

• Tool >> Fill Holes >> Volume command fills holes on a polygonal shell by extending boundaries of shell using diffusion method, after reconstruction by calculation of distance between node point of voxel and vertex .

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

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

Step   

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

1. Select Tool >> Fill Holes >> Volume  from the menu or click the corresponding icon from the Polygon toolbar.  

   If user wants to fill hole in some region. Select region before execution. and then, Fill holes >>Volume command fill holes only in the selected region.

2. Pick shell to fill hole.

3. Following dialogue should be appeared. 

Number of Iteration is polygon depth to extend boundary. If '0' inputted, RapidForm do not extend boundaries and just relocate vertex by voxel calculation like Volume Merge.

Resolution is ratio to average polygon edge. If number larger than ' 1' is inputted. Edge of filled region is larger than selected shell. In other case, vise versa.

If User check Except Biggest Hole option for filling, RapidForm leaves biggest hole unfilled.

If user selected Optimize Mesh option, RapidForm makes a polygon' size regular

4. Using manipulator like below figure, User can assign polygon extension limit.

   

Manipulator is located on selected shell's center position. enclosed box is territory of extension which is limit of polygon extension.

Mouse dragging on each circle rotates enclosed box and on 3 each arrow moves box. 

On RMB menu, User can select Snap Options if user wants to move or rotate enclosed box with snap, user can select Show Transformation Info If user wants to see transform informations 

After transform, select Done to finish transform.

5. Input Number of Iteration, Resolution and select OK to fill hole.

6. After execution, RapidForm makes a new shell with holes filled. 

Result

Before hole filling	After Volume hole filling

Note

• Voxel is 3D lattice having a uniform size internally.
• Make sure that Volume fill hole extends boundary regardless of hole. If boundary
• If Fill Holes >> Volume command is executed on selected region, RapidForm will adds new holes filled shell with size of selected region.
• This command is texture preserve command. So if user don't have Color workbench license, Rapidform shows a below message.

          

  If user select OK, texture will be removed after execution, If Cancel, execution will be canceled.

• Vertex color is preserved during the operation
