Add creases to sharpen
mesh edges.
You
can add creases to mesh objects that have a smoothing level of 1
or higher.
Show Me: Crease a Mesh Face
Add Creases to Different
Subobjects
The result of creasing
differs, depending on what type of subobject you select.
- Edge. The selected
edge is sharpened. The adjacent faces are deformed to accommodate
the new crease angle.
- Face. The selected
face is flattened and all edges that bound that face are sharpened.
Adjacent faces are deformed to accommodate the new shape of the
face.
- Vertex. The
point of the vertex and all intersecting edges are sharpened. Adjacent
faces are deformed to accommodate the new vertex angle.
Assign a Crease Value to
the Edge
As you apply a crease,
you set a crease value that determines how the crease is affected
by smoothing. A value of Always ensures that the crease is always retained,
even when the mesh is repeatedly smoothed. Higher crease values ensure
that the crease is retained through several smoothing processes.
(During smoothing, the assigned crease value is decreased by the
value of the original level of smoothing.)
You can add a crease
to mesh that has not been smoothed. However, the effect is not visible
unless you smooth the object.
Remove a Crease
You
can restore a crease to a smoothed state that corresponds to the
smoothing level for the object. If you remove a crease that is adjacent
to other creased subobjects, their contours are adjusted.
To add creases to a mesh
object
- (Optional) Specify the type of subobject
to crease: right-click in the drawing area and click Subobject Selection
Filter
Face, Vertex, or Edge.
- Select the mesh edges, faces, or vertices
to crease. (If you have set a subobject selection filter, only one
type of subobject can be selected.)
To remove a subobject
from the selection set, Shift+click the subobject.
- Specify the crease value:
- Always retains
the crease at all levels of smoothness.
- Values of 1 or higher sets
the level of smoothness that starts to affect the crease.
The specified subobjects
are creased. A crease is not visible on objects that have not been
smoothed (the level of smoothness = 0).
To change the crease value
of an existing mesh crease (Properties palette)
- If the Properties palette is not displayed,
select any object. Right-click the object to display the shortcut
menu. Click Properties.
- Press Ctrl+click the mesh subobject that
you want to modify.
NoteIf you cannot select
a specific subobject, verify whether subobject selection filtering
is turned on for a different subobject type. (Right-click in the drawing
area and click Subobject Selection Filter.)
- In the Properties palette, Crease area,
Type box, change the crease value:
- None removes
the crease and sets the subobject to the current level of smoothness.
- Always retains
the crease at all levels of smoothness.
- By Level sets
the level of smoothness that starts to affect the crease. When this
setting is selected, you can specify the crease level in the Level
box.
To remove an existing mesh
crease
- (Optional) Specify the type of subobject
to modify: right-click in the drawing area and click Subobject Selection
Filter Face, Vertex, or Edge.
- Press Ctrl+click the mesh subobjects
to be modified and press Enter.
You can also use window
selection to specify multiple subobjects.
