Deform - Surface Push Options
Surface push deform modifies
surfaces of target bodies by pushing tool bodies into them. You select
a customizable pre-built tool body, such as a polygon or sphere, or use
your own tool bodies. Use the triad callout in the graphics area to size
the tool body. Drag the triad 
or set values in the PropertyManager
to control tool body movement.
The surface push deform approximates the surfaces of the tool bodies,
while maintaining the identities of the surfaces of the target bodies
(the number of faces, edges, and vertices remains unchanged in the final
target body).
Surface push deform provides more efficient control of the deform shape
as compared to point deform. It is also a predictable way to create specific
features based on tool body shapes.
Use surface push deform to design free-form surfaces, tooling, plastics,
soft packaging, sheet metal, and other applications where it is useful
to incorporate the characteristics of tool bodies into existing designs.
See Deform

Push Direction
Deform direction.
Sets the direction of push (deform). Select a sketch line, linear edge,
planar face, plane, or two points or vertices. If necessary, click Reverse deform direction 
.
If you do not see a surface
push preview, click Reverse deform direction
. Failed surface push deforms often result from an incorrect
Push direction.

Select the tool body and the top faces
of the target body for Additional faces
to be deformed  |
Surface push affects
only the top faces. The bottom faces are unaffected.

using Bodies to be deformed 
versus Additional faces

Tool Body
. Sets the tool body to use to deform the Bodies
to be deformed (target bodies). Select a pre-defined
tool body from the list: Ellipse,
Ellipsoid, Polygon,
Rectangle, Sphere.
Set the tool body size using the callout in the graphics area. To use
a tool body you have created, choose Select
Body from the list, then select the tool body in the graphics area.
Deform deviation
. Specifies a fillet-like radius value for where the tool
body intersects the target faces or bodies.
The following example shows how Deform
deviation affects the surface push deform.

Tool Body Position
These options allow you to reposition the tool body by entering exact
numerical values. This method is more accurate than using the triad.
, 
, 
Delta X, Y,
Z. Moves the tool body along the
X, Y, and Z axes.
, 
, 
Rotation Angle.
Rotates the tool body about the X, Y, or Z axes and the origin
of rotation.
, 
, 
Rotation Origin.
Locates the center of rotation, represented by the triad 
in the graphics area.
Shape Options
Shape
accuracy 
. Controls the surface quality. The default
quality can be inadequate in high curvature areas. When you increase the
accuracy by moving the slider to the right, you can increase the success
rate of the deform feature. Move the slider only as needed because increasing
surface accuracy decreases performance.
