-
Select the surface.
Notes:
- You can multiselect surfaces.
- To convert a multi-cell curve, select it from the tree to ensure that you select the whole curve instead of one cell only.
- You can mix the approximation of curves and surfaces.
- Use the Exact conversion mode on a NUPBS element to display
the number of control points, the curve order, and the number of curve segments. In
this case, the initial element duplicates.
-
From the
Modify section of the action bar, click Converter Wizard
 .
Depending on the type of the initial element, a text appears indicating what
approximation you can perform:
-
CV: The element is not a NUPBS and needs to be approximated using the Converter Wizard
parameters.
-
EXACT: The element can be converted in
Exact mode.
-
Seg: The element already is a NUPBS.
- Optional:
Specify the deviation Tolerance from the initial surface.
- Optional:
Specify the maximum allowed Orders along the U and V directions
for each surface patch. This value must be greater than or equal to 2, in a given
direction, when the segmentation options are grayed. Otherwise, it must be greater than or
equal to 4 when the maximum allowed number of segments along the U or V is greater than or
equal to 2.
The maximum value allowed per patch is defined in the Order
option in
> FreeStyle Shape Design, General
tab,
Geometry section, and must be
less than or equal to 16.
- Optional:
Set the Segmentation, that is the maximum allowed segments along
the U and V directions. If Single is selected, a mono-segment
surface is created.
-
Click Priority for Order or
Segmentation to define which parameter takes precedence over the
other one.
- Optional:
Click Continuity
 in the App Options panel.
If at least one conversion option is active (Tolerance,
Orders, or Segmentation, that is, you are
not in exact conversion mode), a continuity constraint can be imposed identically on the
selected surfaces.
- Optional:
Click More to display additional options.
- Optional:
Select Information to display further information on the
element.
- Max: Maximum deviation in relation to the initial
element.
- N: Number of control points in U and V.
- o: Surface order.
- s: Number of segments in the surface.
- Optional:
Select Control Points to display the surface's control
points.
- Optional:
Select Auto Apply to dynamically update the resulting
surface.
- Click OK.
