Editable Patch Surface 951

object.
Prior to version 3 of the software, some patch
objects contained a lattice that appeared separate
fromthesurface. Thisisnolongerthecase:
The control framework conforms exactly to the
surface, making it easier to visualize the results of
patch modeling.
The output of the
Surface modifier (page 1–833) is
a patch surface. If you are modeling with splines
and are using the Surface modifier to generate a
patchsurfacefromthesplinecage,youcanuse
an
Edit Patch modifier (page 1–617) for further
modeling.

Turn on Show End Resu lt on the Mo dif y
panel if you have modifiers above the Editable
Patch modifier and want to see the result of all the
modifiers in the modifier stack. This function will
remain on until you turn it off.

To work at a sub -object level:
1.
In the modifier stack display, choose a selection
level: Element, Patch, Edge, or Vertex.
2. Select the sub-object geometr y you want to edit.
To attach an object using Edit Patch:
1.
Select an editable patch object, or an object
w ith the Edit Patch modifier applied.
2. IntheModifypanel>Geometryrollout>
Top o l o g y g r oup, c l i c k At t a c h .
3. Turn off Reorient, if necessary.
4. Select an object to attach.
The object takes on a patch st ructure and stays
in its original location.
The attached object is now part of the editable
patch object. The Tessellation settings for the
original object affect attached objects as well.
To at tach a nd r eor ient a n o bject:
• Turn on Reorient before attaching the object.
The object is both attached and moved to align
w ith the patch object. The pivot of the attached
object matches the pivot of the Edit Patch
object.
To de tach a pat ch surface:
1.
Make a selection at the Patch sub-object level.
2. Ifyouwanttoreorientthedetachedsurface,
turn on Reorient.
3. Click Detach.
A Detach dialog appears.
4. Name the detached surface.
The detached surface remains in place if you
chose not to reorient it. It is deselected and
assigned a different color.
To copy a patch sur face:
1.
Make a selection at the Patch sub-object level.
2. In the Geometry rollout > Topology group,
turn on Copy.
3. If you w ant to reorient the copied surface, turn
on Reorient.
4. Click Detach.
A Detach dialog appears.
5. Name the patch copy.
The copied object remains in place if you chose
