570 Chapter 8: Modifiers
The Cap Holes modifier builds faces in the holes in
a mesh object. A hole is defined as a loop of edges,
each of which has only one face. For example,
one or more missing faces from a sphere would
produceoneormoreholes.Themodifierworks
best on reconstructing planar holes, but c an do a
reasonable job on non-planar holes as well.
Note: This modifier can cap holes in a sub-object
selection passed up the st ack. It caps any part of
theholethat’sadjacentto,orwithintheselected
geometry, whether vertex, edge, or face.
Tips
• If the Cap Holes modifier doesn’t appear to
work, remov e it, apply a Mesh Select modifier
(page 1–719) to select the faces surrounding the
hole, then apply Cap Holes to the sub-object
selection.
• The Cap Holes modifier creates faces with
invisible edges unless you turn on Al l New
Edges Visible before you apply it.
Procedure
Example: To cap a hole in a sphere:
1.
Create a sphere.
2. Apply an Edit Mesh modifier to the sphere.
3. In the stack display, choose the Face selection
level.
4. Select and delete a contiguous g roup of faces.
5. Turn off th e Face selec t ion leve l.
6. Apply a Cap Holes modifier.

Interfa ce
Smooth New Faces—Assigns the same smoothing
group number to all new faces. If possible, this will
be a smoothing group number not used elsewhere
in the object.
SmoothWithOldFaces—Smoothes new triangular
faces using the smoothing groups from bordering
oldfaces.Thissmoothesonlyonelevelinfromthe
perimeter of t he border of the hole, so you might
need to use both this and the Smooth New Faces
option to properly smooth a large hole.
Note: When Smooth With Old Faces is turned on,
the faces in the capped holes inherit a material face
ID from one of the surrounding faces. When this
item is turned off, the f aces in the capped holes are
assigned a new ID.
Tr iangulate Cap—Makes all of the edges vi sible in
the new faces.
